Dr Forwith has gotten me further than any doctor has ever. I was born with conditions and have tried many times to get relief through treatment but since my first visit I could see a difference. There was total honesty about what was possible. This surgery was emotional for me because it was the first time I could feel air going through my nasal passages. Every little thing matters and he gets that.
He was very personable, and he explained everything in great detail. The staff was also quite helpful.
He barely took any time with me, I had to ask about next steps
Very knowledgeable in thyroid health and shows great compassion for his patients. He takes his time to explain medical details in a way the average patient can understand and ensures they are comfortable with that understanding to make informed decisions regarding their own care.
I'm definitely going to give you a five because I feel like your office staff is fantastic, love doctor Forwith and the way that he explains complex situations, and the only negative feedback I have is the communication between the office and the hospital. I'm not sure what side that is on, so I don't want to take away stars because it could be something on the hospital end.
Very professional and friendly! Made sure all of my questions were answered. Top notch doctor! Would highly recommend for anyone in need.
Patient with me with all my questions. Explains things where I understand. He is very knowledgeable.
