I trust my care to Cornerstone Dental and Dr. Zieba. I have been a patient of his for twelve years and I have recommended at least 6 others to him. They have all become happy patients who also recommend him and his staff to their friends. My husband used to be terrified of dentists and now, under Dr. Ziebas care, he no longer dreads going to the dentist!

Best dentist ever! I have had sensitive, cavity-prone teeth my entire life and Dr. Zieba made my entire experience so easy and painless. The entire staff is incredible, accommodating, & transparent. HIGHLY recommend!

Excellent service, no wait, exam and cleaning nicely done with no discomfort!!!

First time patient at the office. Check-in process was really quick. Britney was my tech and she was great, didn’t feel a thing and the appointment flew by. Dr. Zieba was ver kind and personable. No reason to worry about going to the dentist!

Dr. Zieba and Dr. Cinqui are the best! Ive been going to Dr. Zieba for 10+ years, and have been doing Invisalign with Dr. Cinqui for over a year. Both are the best dentists Ive ever had, and my teeth are in the best condition theyve ever been. They are fabulous at explaining whats going to happen and then moving quickly and efficiently to get it done. Their team, specifically Jessica and Cindy, are also very friendly and professional. Their office is new, clean and inviting. I highly recommend Cornerstone Dental of Lincoln Square!

Dr.Zieba and everyone there was incredibly helpful. Such an easy experience with compassion. Would highly recommend Cornerstone Dental.

Everything was as you would hope. No long delays in the waiting room, staff was pleasant and the service was excellent.

I hadnt been to the dentist for years and chose Cornerstone. They were very friendly and helpful. Explained everything well.

Best dental practice in Chicago. Great space, easy parking, friendly staff, clear communication. They take Covid precautions seriously and I felt very safe throughout the visit. I cant speak highly enough about Dr. Zieba and his team.

Who can say they LOVE their dentist... I can! Dr. Mark Zieba and his team at Cornerstone Dental in Lincoln Square set the standard of excellence in patient care, artistry, and talent.Dr. Zieba is an incredibly talented, skilled and personable dentist, coupled with compassion and understanding of patients concerns and needs. His excellent skillset, coupled with his never ending cutting edge thirst for knowledge and procedure, is what makes him, and the practice, the go-in dentistry—HIGHLY recommended.

I have been seeing Dr. Zieba for 15 years and have recommended him to many friends over the years. Everyone has had praise for him and his office.

Thank you for always making it an easy experience from scheduling to checkout. I’m always a nervous dental person but Dr Zieba makes it very comfortable and less worrisome. His sick playlist is an added bonus.

Wonderful doctors and staff!!! They make you feel comfortable with their mannerisms and their knowledge of dentistry. I highly recommend.

Very attentive staff! Always a great experience.

Couldn’t be happier. Shouldn’t have waited a year to transfer from old dentist! Dr Z and his staff are fantastic and I’m thrilled to have such a great dentist in the neighborhood.

Outstanding experience. I would recommend this place without hesitation.

Dr. Zieba, Jessica and Cindy are very professional, knowledgeable, friendly and courteous. Each were thorough and patient in their explanations to my questions and with exam and office procedures. The reception area, exam room and equipment are extremely clean and up-to-date.

BEST DENTAL EXPERIENCE OF MY ENTIRE LIFE!!!!! The entire staff is absolutely incredible, compassionate, humorous, kind, understanding, and pure loveliness. I had not been to a dentist in a few years, and was intimidated to try a new one, but desperately needed to take care of a filling that came out before the pandemic happened. I was terrified to visit a dentist during this time, as well as riddled with anxiety to face the facts of my mouth status. First of all, you deal with Cindy at the front desk, and she is a DIAMOND! I love her and if anything ever happens to her I will rage. She is an angel on this earth. Omg dont you dare disrespect my Cindy. Second, Mark Zwieb the dentist, is a total class act. He took the time to get to know me and understand my goals/fears/neurotic inner monologue. He reassured me the entire visit that things were not as bad as I had made them out to be, and he assuaged all my anxiety about letting someone into my mouth (and lets face it, now my heart). He ensured that by the end of my visit, that I understood what diabolical mayhem was happening in my face hole, and what the plan of attack was. Also, big time honorable mention is Maggie the hygienist - she is the freaking bomb and I was blown away by her efficiency and kindness all wrapped up into one glorious package. And I cant forget to praise Shannon, also a bada** hygienist, who is so down to earth and makes you feel as good as one can while theyre digging around your mouth. Overall I felt very safe by all of the measures they are taking to ensure guests of a sanitary environment, and every action they have taken is thoughtful and reassuring. Cant believe I am saying this but I am actually excited for my next visit! Their office feels like a big hug to me now.

I wont go into detail.But I had a dental emergency and called Dr. Zieda and within 30 minutes he got me in.This man is a complete GENTLEMEN.He helped me immediately and on a follow up visit I explained my situation and HE WORKED with me to resolve an embarrassing situation I found myself in.He is a GREAT DOCTOR and WONDERFUL HUMAN BEINGTHANKS DOCTOR ❤🙏

I’ve been using Dr Zeiba as my dentist for the last 15+ years. He’s the best of the best.

Dr. Zieba is just the best dentist. I have been going to see him for probably 10 years and he has always taken the best care of me and my teeth! I wouldnt go anywhere else. Jessica is the best hygienist and I highly recommend her to anyone that asks. They are a professional team and I love getting to see them both in the new office space. I dont mind traveling a little further to get to see them! You wont be disappointed with selecting Cornerstone Dental of Lincoln Square.

I followed Dr. Zieba from his old workplace Webster Dental as he was the best thing about that place. Excellent care and expert dentistry! Caring environment and great new office with free parking. Highly recommended.

I have been going to Dr. Zieba for years! His entire staff is very capable and professional. I highly recommend this practice.

Mark was great. Very friendly when I walked in the door, super knowledgeable and would explain things to me over when I didnt understand the first time. Very receptive to my needs and took the time to make sure I was comfortable and not in too much pain during my crown.

I’m not really a fan of going to the dentist but this office and staff was amazing! The people who work here really care about your experience. They truly do what they can to make you comfortable and at ease. Will definitely be back.

Cornerstone Dental LS is the best. The staff is kind, accommodating, and understanding. Dr Zieba is fantastic - Ive been going to him for years and appreciate how thorough he is during each appointment. Jessica is my favorite hygienist (although they are all great), and the office is new & easy to get to (theres also parking right next to the front door for customers). Cannot recommend CDLS enough.

Dr. Zieba and his staff are exceptional. They treat you with care and respect, and you can trust that they will be fair in their treatment plan. Ive had several dentists through the years as Ive floated around the country, and Dr. Zieba is the most competent dentist Ive come across.

This place is the best! Great staff and Mark Zieba has your best interest in mind for your dental work. I started seeing him after a bad accident and he was very cautious and thoughtful when having to replace a tooth of mine that got knocked out. I actually dont dread having to go to the dentist now that Ive been going to Cornerstone.

I have been a patient of Dr Zeibas for several years. He is very professional and thorough and has the latest dental technology. He talks through any current or potential issues and gives you options without pressure. Jessica is a seasoned, detailed hygienist and Cindy the receptionist is very responsive to calls and emails. His new office is very clean, has free parking, and tasteful decor. I highly recommend Dr Zeiba and his team!

So happy the new office is open and so easy to get to with parking to boot! Dr Zieba is so personable and takes such care of his patients! I have recommended him to may of my friends and they have all shared the same feelings! Love the clean and very professional office!

Dr. Zieba and his staff are fantastic! Ive been going to him for many years and followed him to Cornerstone from his previous practice. His staff is very nice and friendly. Ive had root canals and crowns done and Dr. Zieba always takes the time to tell you exactly what hes doing next as he goes through each step. His new office is easy to get to, has a free parking lot and is super clean inside. Highly recommend this office!

Dr. Zieba is the ABSOLUTE BEST! I have been going to him for 6+ years and he is a great guy who genuinely cares about all of this patients and takes the time to ensure you leave his office with solutions, great service and efficiency. His team is also wonderful and helpful! Go see him!

Dr. Zieba and crew are super professional and do a great job. The new space is very well done and he leans on the newest technology to serve patients. Highly recommended.

I’ve been seeing Dr. Zieba for the last 10+ years and have had nothing but excellent experiences. Unfortunately, I’ve needed quite a bit of dental work over the years, but his service has always been outstanding and he’s made the experiences as comfortable and painless as possible. He also always seems to have the newest gadgets and technology which make the visits faster and more efficient. His new office is great and the staff is very friendly and accommodating. If you’re looking for a new dentist, I highly recommend Dr. Zieba and Cornerstone!

Are you a roadie if you follow your dentist to his new gig? If so, I am Dr Zieba’s devoted roadie! I have been seeing Dr Zieba for some years and when he opened his new dental practice there was no question I would be right there with him. He genuinely cares about your visit and your care. The staff at Cornerstone is so professional and attentive to any and all of your needs. Best care and best people. Beautiful offices too!

I have been going to Dr. Zieba for about 12 years now. I went to his old office and followed him to his new office and couldnt be happier. Jessica, his hygienist that came with him from his old office, is the best. Its always a great experience with Jessica and Dr. Zieba. New office is beautiful and the best part is they have parking!

Great staff! Beautiful new office! I’ve been seeing Dr. Zieba for over 10 years. Happy he found a great new spot in Lincoln Square.

Dr. Zebia is awesome! The office is super clean, the staff is extremely friendly, and dentist visits are a breeze. My husband and I would both highly recommend!

Nice

I met several dentists in Chicago before I found Dr. Zieba. As a veterinarian who does comprehensive dental assessments and treatments every day as part of my practice, I admit I hold my dentists to pretty high standards. I wish I had found Dr. Zieba sooner. His commitment to patient care and progressive practice was immediately apparent. I recommend him to all my friends, staff members, and clients.

Been seeing Dr. Zieba for 10 years now. Best dentist in Chicago, hands down. Beautiful new office at the north end of Lincoln Square on Foster Ave., great staff, and special shout out to his hygienist Jessica, she’s awesome! Highly recommend this office, you won’t be disappointed.

Great new office and I know the dentist is great since I used to see him at my old place as well. Highly recommended!

Ive been going to Dr. Zieba for my dental care 5+ years now. He is the man and his team is incredible. Cornerstone Dental has made teeth cleaning visits enjoyable!

Dr. Zieba and his staff are fantastic! Dr. Zieba has been my dentist for many years and my oldest children now see him, too. I have always appreciated his care and concern for his patients. He’s really down-to-earth, is a great dentist, and I can’t recommended him highly enough.

Cornerstone Dental and Dr Zieba are fantastic. Not only is it easy to get to from the city, but there is a parking lot attached. Dr Zieba and staff are professional and truly cares about the patient. I highly recommend Cornerstone Dental. My teeth were pretty crooked and they were able to fix my smile with some amazing technology.

Dr. Zieba is absolutely the best dentist! He is knowledgeable, personable, compassionate, and an all around joy. He surrounds himself with staff of an equal caliber so its always a pleasure to be seen by him and his staff. His new practice is clean, well-equipped, and easily accessible. I highly recommend Dr. Zieba!!

I’ve been a patient of Dr. Zieba’s since 2014. I was so happy to hear he opened a new practice. The office is beautiful and his staff is great! They have parking on the side of the building which is a plus in the city.

Dr. Zieba and his staff and professional, warm and trustworthy. I have been a client of his for many years, and wouldnt dream of going anywhere else.The new office is modern and comfortable, with easy parking on the west side of the building.

Dr. Zieba and his staff are the best! They go out of their way to make you feel comfortable and the brand new office looks amazing.

Dr Zieba is the best. He is so patient, gentle and honest. Beautiful office and friendly staff!

A good team of people who make going to the dentist less stressful! Dr. Zieba and his team has been taking good care of my teeth for years now (both at Cornerstone and his previous office). I cant say enough good things about Dr. Zieba and his hygienist Jessica.

Just terrific in every respect - care, courtesy, scheduling, cleanliness.

Doctor Zieba was great and the staff was wonderful. They got me in last minute to fix a cavity before my vacation. Thanks y’all.

Great office + easy parking! Dr. Zieba and his team are the best! Shannon was very professional, informative and easy to talk with. So happy Dr. Zieba opened this new location!

If you’re lookong for a new dental office - this is the place! I love my hygienist! Jessica is great! Fortunately, I have pretty good teeth and no major dental issues, so my visits to the dentist are just for cleanings and Jess is the best! Dr. Zeiba is great, too! Always super personable and talks to me about my teeth. Last visit, he found a tiny cavity and filled it on the spot. Super convenient, so I didn’t have to make another appointment and come back. That was only my third filling (and I’m over 40!). I get nervous about that kind of thing and Dr. Zeiba was patient and kind. Easy peasy lemon squeezy.

I have been a patient of Dr. Ziebas for over 10 years and I am so happy he opened his brand new (and beautiful) office in Lincoln Square! Dr. Zieba is incredibly kind, knowledgable, and truly cares for his patients. The rest of the staff is wonderful as well. I highly recommend Dr. Zieba and Cornerstone Dental of Lincoln Square.

Ive been treating with Dr. Zieba for over 10 years including well after I moved out of the city as have many of my friends, family and co-workers. My experience only got better recently with Conerstone Dentals improved treatment technology, parking, and decor.As for the actual care, Dr. Zieba, his hygienist Jessica, and his staff continue to take every possible step to make patients feel welcome, comfortable and taken care of. Fortunately my insurance is accepted at Cornerstone but I still had questions and they were happy to answer all of them.

Dr. Mark Zieba is a great dentist. I’ve gone to him for twice yearly exams for over 20 years. He really knows my teeth and my history. He’s very knowledgeable about teeth (and gums, and bite, etc.) and their interplay with general health and quality of life. And he shares his knowledge of dental health, from childhood through old-age (I’m closing in on that) with his patients. On the rare occasions I require a procedure, I aware the implications down the road. I always know what going on and what I’m in for.Dr. Zieba has a relaxed manner that puts me at ease. He’s a good listener and is respectful of my time and financial limitations. I feel very comfortable visiting him. His office is spic and span.I repeat, Dr. Zieba is a great dentist and runs a great shop. I had no hesitation in following him when he switched practices. I have a full mouth of teeth and excellent dental health – he made a major contribution to this positive outcome.07/28/2020 - Just had another appointment. COVID-19 response and revisions to standard procedures all very clean, clear and organized. Same first rate service. JRH

Great new dental practice, was very happy with the service and highly recommend.

Beautiful office with excellent dentist and staff!
