I am a new patient of Dr.Nitasha Kuma.
My visit was for osteoporosis and what treatment would be best for me.
Dr.Kumar explained in easily understood terms my options, medications and injections.that might affect the warfarin that I take.
I found Dr Kuma.to be very knowledgeable,
very pleasant and easy to talk to.
I will accept her treatment suggestion.

Dr Matsumoto is outstanding. He takes time to explain causes and treatment plans going forward. I’ve only had the pleasure of knowing him for a short time but I was very comfortable with his decisions and treatment. I know he is retiring very soon and I wish him all the best. I look forward to meeting with Dr Potter in several months.

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.

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.
