I love DR CALDERON, I FOLLOWED HER TO THIS CLINIC FROM THE LAST CLINIC SHE WAS AT. She spoke with me about my concerns, she checked my physical status and we spoke about my medication choices and behavioral choices.


Everyone in the office is always very helpful and courteous. Dr Kosmatka is an outstanding doctor. Thank you for taking care of my health.


Dr. Yu has an excellent approach with her patients. It is my belief that it stems from her years as a nurse, that helps her relate with her patients. I have been a patient of Dr. Yu for almost 20 years and I am always pleased with the care I receive.


Exceptional care always. very pleased with Dr Clark and staff.


Dr. Calderon is very helpful in providing me the information I need in my weight loss journey. She has given me guidance and I look forward to my follow ups with her.

Always treated with respect and kindness, from the moment I walk in to the time I leave. Thanks Dr. Clark
