I love the doctors and the nurses here.

I love the doctors and the nurses here but their service is very slow. I've had to wait in the patient rooms for over 30 minutes with no one to check up on me and it feels like I'm trapped in these rooms feeling forgotten... it's also very contradicting and time wasting especially since they tell you to come in 15 minutes early.

came up with a treatment plan that I’m comfortable with.

Patient of Dr Bennett but seeing Dr Pepek for the first time. The wait was short which is always great. Dr Pepek took her time listening to all our concerns and came up with a treatment plan that I’m comfortable with.

Dr Grace Kasamatsu who has been seeing my son Ian is always a pleasure to see once a year.

Raquel the medical assistant was very nice and helpful. She is new to the practice and did a great job. Dr Grace Kasamatsu who has been seeing my son Ian is always a pleasure to see once a year. She genuinely cares for the well being of my son. We are so lucky that we are able to continue to see her. Love that they upgraded their systems to something modern and hopefully i can someday book appointments through the Healow app too.

I had forgotten to bring my children’s sports forms which I had to get signed. The front desk printed them out for me and filled them out! Dr. Pepek of course is amazing, and so is her staff.
