I cant say enough about the type of service that weve received from HDH. Weve been looking for an inspection partner like this for awhile. HDHs turn around times are second to none in this industry. The pricing is transparent and Jack and the quality team at the lab are thorough and efficient to the point where we feel like the only customers. Thanks, HDH.

Most capable lab for dimensional measurement and contract inspection in Southern California. Impressive reporting, quick lead times and very competitive pricing.

I got the pleasure to work very close with Jack and his team of inspectors. I must say that the skills and advance equipment they have here at this lab is beyond words.
