Dr. Hagamen's demeanor was very calming which I appreciated since I was quite stressed about my condition. Dr. Hagamen and his team were very helpful and took the time to explain what they were doing and why. I was able to leave with a better treatment plan and understanding of my condition. I would highly recommend him and his team. it was the best doctor visit I've had.

He has never made me feel rushed - but takes time with me. Which is perhaps why he arrived 30 minutes past my appointment time. Why no give him longer appointment times. His care is superior.
