I had an extensive cleaning by Ingrid for my first appointment of the day. For my second appointment Dr. Evans adjusted my bite, after a thorough explanation and dental molds had previously been taken. The condition and appearance of my smile has been greatly improved over time. There's a lot that goes into proper dental care, and it's definitely worth the effort. They explain things well before the work is begun, and ask about how I'm doing throughout the process. And they use top of the line technology. Dr. Ruprecht has a great practice in place and I'd highly recommend them for periodontal care.

Dr. Ruprecht,was excellent, as always. I like to mention in particular, Ingrid, the hygienist. As in the past, she was very thorough, informative, and efficient. She took care of the issues in my mouth and she provided very satisfying solutions. As a whole, a very rewarding experience.

I came to Dr. Ruprecht feeling embarrassed about what was going on with my mouth and carrying a lot of anxiety. She was incredibly gentle and made me feel cared for and at ease. After years of not knowing what was wrong, I finally got a diagnosis. She also uncovered a significant amount of restorative work that needs attention following treatment I had with Dr. Sands in Beverly Hills. She took the time to explain everything to me, and I finally feel like I’m on the path to getting this resolved and having my life back. She even prayed for me, my health, and my family. Dr. Ruprecht is truly one of a kind, and I feel like God brought me to her.
