Patient Reviews

Excellent experience! Addressed Issues that I’ve dealt with for many years and resolved them efficiently. A great staff and vibe….

-O.B. (8/2025)
We had an excellent experience at Dr. Ishii .The office was welcoming and beautifully organized, creating a comfortable atmosphere. Dr.Ishii and Carly, were incredibly kind and thorough during my daughter‘s visit taking the time to address all our questions and concerns. Highly recommend this practice.

-J. (6/2025)
Dr. Ishii is thorough, knowledgeable and caring. She and Stephanie outline a treatment plan tailored to the individual needs of each patient. Dr. Ishii's team schedules both routine and surgical appointments to ensure the most proper and efficient care. I could not recommend Bryn Mawr Periodontics enough.

-L.D. (2/2025)
I had a great experience with Dr. Ishii and her staff. Dr. Ishii performed a gum transfer surgery to replace lost gum after an implant. The hardest part was convincing myself to go because I had too many bad experiences with dentists. The surgery was fast, painless, and without any complications. Dr. Ishii was compassionate and caring. I wish all doctors were like her.

-H.S. (11/2024)
If you're looking for a place to care for your gum issues, you need an implant, or have a complex dental situation, look no further! Dr. Ishii sometimes has a wait-list because she's just that good. Trust me, she's worth it.
