Great place to go, fair prices and great awesome service.. They do have the best hygienist their without hurting your gums..

Dr. Mahon is an excellent dentist! He has a calming personality and is very professional. His staff is also skilled and professional. The office is clean, comfortable and organized. I’ve been seeing doctor Mahon for several years, I’ve never been disappointed. I get 4 teeth cleanings a year by the hygienist Libby. She is the best hygienist !!!!! I absolutely recommend Dr Mahon and the entire staff at Sienna! If I could give them 10 stars for satisfaction I would. ⭐️

Great experience at Siena Dental. Called and got an appointment within 2 days. Fantastic availability and service. Once I arrived my wait time was less than 10 minutes. Dr. Mahon and his staff were attentive and professional. I am impressed by their office, exam rooms and thoroughness.

Wonderful dental office, efficient and friendly staff. Dr Mahon is very good dentist identifying issues but no pressure, work plan discussed and pricing shared in advance of scheduling, no surprises at time of work. Nice to be in office with up to date sophisticated equipment. Krisdie was my hygienist, very friendly and feel I recd very good cleaning, not just quick skim over. Office is easily accessible on Eastern Ave with ample parking in front. Happy to be patient here.😊

My family and I have been going here for years and Dr. Mahon and his staff never disappoint. Libby has been an amazing dental hygienist. Thank you guys for taking care of us for all these years!

Excellant service. Very nice staff

What makes a great Doctor, in any kind of practice, isn’t their knowledge. It’s their ability to listen to their patients and be open and understanding to what they’re saying. Dr Mahon is a great Doctor. His staff is top tier as well.

I went to Dr. Mahon for his second opinion on a crown. Dr. Mahon is very knowledgeable and relaxed, never gave me any pressure to receive treatment from him. Everyone in the office is nice and kind.

Dr. Mahon and staff are nice, caring, informative and always does good work, Libby is the best when it comes to my scheduled cleaning, Dr. Mahon is a talented dentist, my family and I have been going to their clinic for many years now and we have no plans on going elsewhere, Sherry at front desk is super helpful, I highly recommend them!

Dr. Dave and the entire staff of Siena Dental are most assuredly top shelf and # 1 Rated - Excellence in Dentistry and Customer Service in Las Vegas. In each visit, I have been able to reduce my periodontal issues and feel better with every visit. I thank you and my smile thanks you too. Craig Brown

The best service ever, from front desk check in to the check out!! Tech and Doctor are the best!!

Dr. Mahon and his staff are consistently outstanding.Special recognition to Shari the office manager/receptionist who is always so pleasant in greeting you when you enter the office. If there is such a thing as looking forward to seeing your dentist then Dr. Mahon is the guy.

Great Staff. Krisdie is exactly what you want in a Hygienist, careful and meticulous, and Dr. Mahon has a great patient interaction and is very knowledgeable. Dentist appointments can be uncomfortable, but I am never nervous visiting Siena Dental.

I have found a great Dentist! and dental office. My experience at Dr Mahons office was exceptional! I was scheduled immediately after expressing my dental emergency, was seated on time, and was treated with professionalism. Dr Mahon and his assistant Lourdes were very gentle, and compassionate. I was very pleased that I experienced no discomfort whatsoever after my procedure. His injections were painless! I would highly recommend him and his team for all your dental needs!

I have going there for years. Libby is the best my she still does the best cleanings. Dr Mahon does wonderful work and all the staff is helpful and friendly.

Fabulous experience, great work, very professional, and reasonably priced!

I have to say I am very pleased with the customer service and level of expertise from these professionals. I am also thankful for the work theyve done for me and have been very happy with the results. Theyve made sure I am comfortable through each process and are excellent at keeping you informed on whats being done. Dental hygienist Kristy (I hope I am spelling her name correctly) is excellent- super friendly and knowledgeable. Definitely recommend this place.

I have been coming here for years! I always get taken care of for all of my dental needs. I feel they are reasonable in their dental fees. If your looking for a new dentist, give Dr Mahon at Siena Dental, on Eastern Ave, Henderson a shot! I think you’ll be happy with their services.

I’ve been a patient at Siena Dental for years. Truly the friendliness and most professional group of people anywhere.

Sienna Dental is great. The staff is friendly, efficient, and very nice. I have had the same dental hygienist for 17 years and she is extremely detail oriented. My experience has shown Dr. Mahon to be honest, gentle, and up front with what work he deems necessary without any pressure. His honesty and understanding must be why his office is so easy and drama free.

I have been going to SIENA Dental for nearly 20. Libby has been my dental Hygienists all these years. She is amazing technician and caring friend. Always provides helpful information ref dental care. She is very positive and loves her clients. I will not consider going anywhere else. Dr Mahon is amazing and makes me feel so comfortable when I see him. Very friendly and caring. My husband and I love this clinic and it is part of our lives. Thank you Dr Mahon and the entire staff for caring and for providing amazing service to your clients.

The place is spotless clean, the staff is wonderful and Dr. M is the best!!

I have been a patient at Sienna Dental for over 10 years. Dr. Mahon is professional and the office is always in tip top shape. Libby my dental hygienist is one of the kindest people that I have ever met. She makes you feel comfortable and safe while cleaning your teeth. I wish I lived a little closer to their office, but the extra commute is worth the great service.

Great place to have your teeth worked on.

My original dentist retired. I spent a year with his replacement then decided it was time to move on. Im very very happy with Dr. Mahon. I can tell the difference. His staff is friendly and Sharon is welcoming. Also let me add, I did my research.

If you have to go to the Dentist, I highly recommend Siena Dental. I have lived here for over 50 years and hands down THE best, check it out for yourself, I think youll love it.

Going with the family 5kids and wife for the last 15 years .Kudos to Dr Mahon and the Best Best staff ever .

We are moving from Vegas and will no longer be using Siena Dental. I just wanted to thank you so much for the excellent care we received over the years from Siena Denta. Libby is the BEST!!! hygienist I have ever had. Take Care & Happy Holidays to ALL at Siena Dental.

I come here every six months for my regular check ups. Everyone in the office is so friendly and welcoming. Libby always takes such great care of me during my teeth cleanings. The dentist is such a nice guy and only recommends doing work on your teeth if you absolutely need it. I always recommend Sienna dental to coworkers friends and family members.

Dr. Mahon and his staff are extremely professional and are always sensitive and kind. I have had some bad experiences with other dental groups. I have never had a bad experience with Dr. Mahon and his dental group. I leave feeling nothing but love for their team.

Very very good; they always do an excellent job

Gentle workers and effective treatments . Highly recommend .

Doctor Mahon & his staff are Top shelf & Highly Professional. The good doctor fixed my teeth with little discomfort or pain. Strongly recommend anyone having issues with their teeth (or would just like to have an excellent Doctor and Dental Staff) make an appointment to see him.

I’ve always been scared to get a filling because of past experiences, but this dentist is beyond amazing I was able to relax he also stopped to make sure I was okay. I was a few minutes early and they took me back right away. Its very hard to find a great dentist, I would definitely recommend this dentist. The lady who cleaned my teeth my first visit was awesome as well!

I’ve been going to Siena Dental for about 15 years. The staff is great.Never had to wait!Libby is my favorite! She’s the Dental hygienist!Very sweet, great personality & great with her skill to clean teeth with little discomfort.I highly recommend Siena Dental!Dr. Mahon is an awesome doctor.

They squeezed me in on short notice. It was my first appointment and they got me in on the date I needed.(less than a week) front desk, Hygenist, and Dentist were all very friendly and did an amazing job.

Always a great experience I highly recommend this office. Dr Mahan is an excellent dentist and the staff are always very courteous. Thank you all

I am terrified of going to the dentist! When I walked in the door all that fear went away. From the time I checked in until I checked out I have never felt so comfortable, safe, and so welcomed. Very friendly staff and each one shows they care about every patient individually. I so recommend you go!

Courteous staff and Im always seen on time. My hygienist, Krisdie, is awesome. Dr. Mahon explains findings with care and detail. Their location is on the opposite side of town from where I live but I dont mind because I always come out feeling I got the best care. I never thought Id find a dental provider that doesnt push for unnecessary, expensive procedures, until Siena Dental. Im very impressed by the level of professionalism and integrity shown by all the staff. Thank you.

Best dental experience I have ever had! Top noch place! Very professional, experienced and caring people, the whole office: front desk, nurses and the dentis himself. I am thankful for them. Extra special thanks for nurse Laudres. Her 20+ yrs of experience (and the fact that they all care) really made a difference keeping me 100% confortable during my root canal treatment. From the bottom of my heart THANK YOU Siena Dental.

Started going to Siena Dental back when I lived in Henderson now living way out in north west its quite a journey but well worth it. Dr Dave is great and his staff is awsome and l luv my Cleaning hygienist Libby.

I truly wish Id found Dr. Mahon when I was younger, I would have never had a fear of the dentist. Time is important to everyone, and the staff truly respects your time. Im in the chair getting my work within 10 minutes of arriving. Dr Mahon is the absolute BEST he takes his time to make sure your work is done properly and hes super quick. I would recommend him to anyone looking for a dentist.

I love Siena Dental. The Dr. is professional and nice. I always say the backbone of any Dentist is the Hygienist and let me tell you that Libby is amazing. The office staff is so friendly as well. I recommend Siena Dental.
