Dr Ahn is AWESOME! A few months ago I was in so much pain I could barely walk. She correctly diagnosed me with PMR and I am pain-free, sleeping well, and loving life again. Thank you Dr Ahn!!

Dr. Ahn was prepared and had obviously reviewed my chart of 40+ yrs. as she was aware of the many meds, numerous surgeries and current treatments. This put me at ease and allowed us to move to address current needs and evaluations.
From the front desk, her PA, and xray tech, everything was professionally executed. Thank you ARA.

Great Experience. First time visiting the office and Dr. Potter. Staff were friendly, courteous, and professional. Dr. Potter listened and took notes as I explained the medical issue to him. Dr. Potter is kind, very compassionate, attentive, professional, and provided me with information. Dr. Potter was very thorough. Can't say enough about how GREAT he is. I HIGHLY RECOMMEND Dr. Potter.

I am devastated the Dr. Matsumoto will retire this month. I am fortunate to be the daughter and wife of two brilliant and dedicated physicians. I know a lot of good doctors and some who shouldn’t own a stethoscope. Dr. Matsumoto is among the very best of the best.

Dr. Potter is always so helpful. He’s an excellent listener and his demeanor makes his patient feel comfortabl. I drive nearly 3 hours to see Dr. Potter every 6 months, and occasionally, more often. He has helped me manage my RA. At 76 years old, I’m still playing senior softball, pickleball, riding my bike and walking, partly thanks to his efforts.
Oct 7, 2025
Dr Ahn has a pleasant, quiet, and calm demeanor. She is not an alarmist. Listens to her patients and recommends sound treatment plans to target the patient’s condition. I do recommend Dr Grace Ahn to anyone looking for a good RA Specialist.

Very good. Doctor Potter is personable and attentive. He listens to my issues even when sometimes the current problem might be peripheral to my arthritis. I think these conversation are useful to understand the whole person and to avoid any meds that might aggravate another condition.
