Dr. Schueler's grandmother was a big influence in his decision to become a doctor. She “lured” him into the profession by telling him interesting stories about her job as a nurse and bringing home stethoscopes and syringes for him to play with.

Dr. Schueler finds the medical profession...

challenging and rarely boring. I enjoy being my own boss…there are always new things to learn and new people to meet.

Dr. Schueler tries to keep an open mind to alternative medicine.

As a medical doctor, I’m an advocate for the patient and tend to apply science to alternative medicine. There are things people can do to take care of themselves, simple things…I’m please to find that people in Buffalo are interested in doing things proactively.”
