Working with Dr. Katalin Frisch was one of the best doctor experiences I’ve had. She was detailed and caring, I felt heard and that everything I was feeling mattered. She took time to explain tests that I’ll need to take and possible outcomes. She throughly went through my symptoms my past results and anything else in my life that could be impacting my current symptoms. I’m so happy I got the experience to work with Dr. Katalin Frisch and grateful I get to keep working with her in the future.

Dr. Frisch is the BEST Doctor. I can't say enough good things about her. She is brilliant, thorough, attentive and kind. Dr. Frisch is incredibly responsive to any medical or prescription questions via calls or emails. Her office is beautiful. The staff is friendly and helpful with appointments, follow-ups and insurance questions. In a world where medical staff always feels rushed, it is such a pleasant surprise to have a FIVE-star experience. After one visit Dr. Frisch was able to adjust my medications to control menopause symptoms. I have successfully lost over 40 pounds under her care. She has been a life changer for me. I've referred several of my friends and they all love her!
