I have been a patient of Dr. Karen Thampoe for a few years now. I have never had a physician I felt truly comfortable until being in Dr. Thampoe’s. Her staff is always friendly and highly trustworthy. I will not be changing doctors and once you see her, you’ll know. No nonsense and listens to your needs.

Great office and staff. Dr. Thampoe has been my Dr. for three plus years. She is friendly and very detailed. My yearly physicals are very extensive. This is a great place for general medicine.

I just had a follow up visit with Dr. Thampoe, she is very professional. I love coming to this office, people are very accommodating and makes my day, the staffs makes me smile all the time.
