Dear Randy,
I want to thank you for doing such a wonderful job on my denture. You will not believe this - but the denture feels better than any partial I have ever had. In fact I can't remember the last time my teeth have felt so good. you are a true professional and a very special person. You saved an old lady from a nervous breakdown!
Your whole staff was like family - they were courteous and friendly. Please give them my regards.
Thanks again with god's love.

I have been a patient of Dr. Lonsbrough's for several years. When I came to him I had some of the earliest implants. I explained that I had limited funds and he worked with me to try to keep as many of the older ones while adding ones that would keep my dentures in good order. His knowledge of the latest technology and ability to be flexible were much appreciated. Both he and his staff are competent and professional. I highly recommend his work.

Thank you so much for the high level of care you provided me. All of you were always cheerful. sincere and caring. Dr. Lonsbrough's office is a wonderful place to visit and receive TMJ treatment. Also thank you for all your generosity in providing me a new mouth piece. It is very comfortable and helps me a ton!

Thank you, McKenzie Garcia
