In a community where medical care is faultering, caring and compassionate doctors lacking, Doctor Gallen stands out and I feel so grateful and appreciative to have him. He's one of the few doctors out of many I've been to that doesn't quit listening after 10 seconds, always takes the time to answer my questions and his care is above reproach.

March 02, 2024
Dr Gallen is a good doctor. He always works with me in regard some other medical problems. I'm quite comfortable with him, and respect him. Based on past experiences with other medical types, I have little respect for doctors. I respect Dr Gallen. He is a healthcare professional, not a hack who could kill me with indifference or complacence, unlike 2 other Asante doctors.. I appreciate him. I'm terrible with names, so I can only identify her through my appointment, and that is the NA who took me in, checked vitals and went through my extensive med list. I wish I could remember her name, because she did a great job. She was both friendly and professional, and did all the things she needed to do thoroughly and competently. She is a credit to your office. Check my chart and tell her I said "Good Job!"

February 21, 2024
Every contact that I’ve had with Asante personnel in the past year has been positive. This includes Dr Gallen, who I saw most recently. He’s a good communicator and I got the sense that genuinely cares about me as an individual. The only complaint I have is that his office location doesn’t exactly match the address listed on the website. That needs to be updated, because it was a bit confusing to find his office. Fortunately I still made it on time.

I wish every doctor was like Dr. Gallen. He always remembers my history. He is aware of new technologies in managing my type 1 diabetes and has been proactive in encouraging me to make changes that have resulted in positive, tangible outcomes. He is friendly, patient and takes me seriously, which is something I especially value as an older woman, who has to spend a lot of effort on "proving myself" whenever I encounter a health provider nowadays.
