John D. Tyo John D. Tyo,

John Tyo has spent his entire life around prostheses and prosthetic users. In fact, John took over the business from his father, Howard, himself an above knee amputee since the age of nineteen. As John was growing up his father taught him how to hunt, fish, ice skate, drive a boat and water ski, all activities Howard enjoyed with his friends, many of whom were also amputees. John became involved with helping out in his father's "shop" at an early age. His involvement in the field is both intimate and lifelong. He has a very firm grasp and personal knowledge of the unique challenges of living life with an amputation. John studied prosthetics at Northwestern and has been involved in continuing education in the field, both teaching and learning, ever since. He has a reputation in the field for being at the cutting edge of new developments, and is frequently involved in beta testing new innovations. A past disabled instructor and guide, John has been involved with National Handicapped Sports for many years first on a local and then a national basis.

Certified by The American Board for Certification in Prosthetics, John has a clinical affiliation at VA Medical Center, Syracuse. He is a member of the American Academy of Orthotists and Prosthetists, American Orthotic and Prosthetic Association, Amputee Coalition of America, and past director of the International Association of Orthotists and Prosthetists.

Sheila Harrington

Sheila Harrington,

Administrative Manager

Sheila embodies the heart and soul of SPOC. There is a mountain of "behind the scenes" work required to provide the services needed to return our patients to an independent life. The insurance reimbursement system has become almost insanely complicated and difficult to negotiate. Sheila's skills gained by working with insurance companies and/or a third party payer's ensures our patients receive the funding they deserve. Sheila takes an active interest in every person who walks through our doors and makes sure the patient's interests are best served by their insurance carriers. Sheila is a native of Syracuse and resides in the eastern suburbs. Sheila enjoys golf, gardening, cooking, and bird watching. She is an avid fan of Syracuse University sports.

"I have been to many prosthetists since losing my leg. I am now in the most comfortable socket I have ever worn. I am able to wear my prosthesis for 16 hours a day without discomfort. When I am not working, I enjoy biking, hiking and canoeing." – Ron Hepler, Williamson

"I have an above knee amputation. I'm 89 years old and I use my prosthesis all day, every day. If I'm not a walking advertisement, there's no such thing! I highly recommend these folks to anybody." – Sidney Greenberg, Cazenovia, NY
