1st time that I have been under care of an ENT. Dr Forewith very professional and approachable.
Dr. Forwith and his assistants made me feel very comfortable during my RFA procedure.
Dr. Forwith is the best and he took very good care of me! I am so thankful we found him. It gave me peace of mind knowing that he would do the ultrasound himself. He explained my options well. I was afraid of the pain of having a biopsy but he is so experienced and skilled that it was not painful like I was afraid of. I would highly recommend him. We drove two and a half hours from home to see him, and would do it again, completely worth it. Thank you, Dr Forwith!
Very easy to talk to. Discussed all options. Everyone was great.
He was great, first time experience with him. Happy to have him along the ride with my son
As usual Dr Forewith was professional and proficient
Dr Forwith has taken excellent care of my thyroid problem. Very nice to work with. Would recommend him to all
Dr. Forwith was my third doctor I went to. I wasn’t getting any answers. He and his staff has been wonderful to work with. He performed my hemithyroidectomy and you can barely tell. He really cares about his patients and their quality of life.
Very pleasant Dr. would highly recommend.
Medical service is excellent as usual Kind respectful doctor & staff However, sat in the examination room for about an hour before I was seen.
