 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.
