Our Physicians

Dr. Sandra HellmannSandra A. Hellmann, MD, FAAP 

“I often refer to my patients as my kids. I enjoy seeing them becoming their own person and, later on, starting to make their own decisions.”

Dr. Hellmann joined the Wayne Medical Group in July 1995. She began practicing in the Sodus office and moved to the Williamson office five years later. She earned her medical degree at the State University of New York at Buffalo School of Medicine, and subsequently completed the pediatric residency program at Columbus Children’s Hospital in Columbus, Ohio before returning to her western New York roots.

Outside the office, she enjoys spending with her children, reading, knitting, swimming, and working in her gardens.


Dr. Jan WalkerJan Walker, MD, FAAP

“I love playing with the children and watching them discover the world.”

In high school, Dr. Walker discovered she liked people as much as science, and decided that using science to care for people would bring her more joy than advancing the field.

Dr. Walker joined the Wayne Medical Group for the first time in 1992, where she practiced at the Wolcott office for eight years before beginning subspecialty training in Development Pediatrics at the Kirch Developmental Services Center at the University of Rochester. She was a member of the Unity Pediatric Development Unit, involved in subspecialty developmental behavioral practice, until returning to the Wayne Medical Group in 2006. Her special interests include learning and behavior problems.

Dr. Walker attended medical school at the University of Michigan. She completed a flexible internship at Henry Ford Hospital in Detroit and her pediatric residency at Children’s Hospital of Michigan in Detroit. She swims to stay fit, and enjoys spending time with her husband, adult sons and extended family.
