Marc Werner has been amazing and has given us attention, service and care beyond what anyone could expect! He has been sensitive to my daughters' concerns about their spinal braces and has armed them with everything they need physically and mentally to be as successful as possible with their braces. Marc helped me with my knee brace several years ago when I tore my ACL and I will continue to go to him and recommend him to anyone who might need a prosthetic or brace!


I came to Long Island O & P after having problems with a previous O & P office that failed to meet my needs. I was very pleased and overjoyed at the level of attention Marc and his staff met me with. I had a very antiquated partial foot prosthesis that wasn’t meeting my day to day needs. After consulting with Marc and his staff they showed me the future in partial foot prosthetic devices and I was beyond thrilled to be in receipt of this new technology. I had a great experience with the office and am happy to say I am now functioning better and walking comfortably with my new modern partial foot prosthesis.


Out of six braces (fabricated at other Orthotic facilities) this is the first time that I put it on and had it feel comfortable right from the start. The only adjustment was me having to learn how to put it on right, which is phenomenal.

8 months ago, I became a paraplegic. Today, with your skills, I was able to stand once again.So many emotions and thoughts were going on in my head. During the drive home, Pat and I talked about all the possibilities and doors that will open for me. The quality of life for me will now change for the better! I can't thank you enough!

I was introduced to Long Island Orthotics and Prosthetics by a mutual friend. There was an immediate difference in my experience from the minute I walked in the front door of their office. At first, I was nervous but felt right at home and comfortable with the personalities and professionalism of the entire staff. The care I’ve received has been top notch. My temporary socket fit me like a glove immediately. They cared more than any Prosthetic office I ever dealt with and the finished product and componentry I received from them has enabled me to be more active and have a better quality of life. I highly recommend LIO&P to anyone needing any of their services.

I have been using orthotics devices for over 9 years. Marc Werner at Long Island Orthotics and Prosthetics is the best. I enjoy using LIOP for their service. The Staff is amazing and professional. The office is fun and inviting. I highly recommend coming in for all your bracing needs.

You do not know me and I don't know you, what you did for me yesterday is a good reason why I still believe there is some body up there. I don't know how to thank you. You are a good person, you did not do that for money, you did that because you are a good person. That coming from my whole family. God Bless you!


The services provided at Long Island Orthotics and Prosthetics are unsurpassed. The techniques and componentry LIO&P uses are state of the art and of excellent quality. Their light-hearted attitude lends itself to the bad situation made good. It's not much fun being an amputee, but their upbeat, positive attitude and jovial manner make it much easier.

On June 5, 2017 while training for a bicycle race, I was struck by a vehicle and rendered unconscious. From the accident I was airlifted to Stony Brook Hospital where I spent 8 days in the Surgical ICU with a host of serious injuries, including three broken vertebrae and displaced discs.
When I was transferred to the Westhampton Care Center for rehabilitation to begin physical therapy, I was fitted for a back brace by Marc Werner of Long Island Orthotics and Prosthetics. Just a day later Mr. Werner came to my room with the constructed brace, and invested more than an hour explaining its fit and dynamics.
After I expressed my gratitude for the time Mr. Werner took on a Friday evening, to not only explain the detail of the brace, but to learn about me as a patient and as a person, I asked for Mr. Werner's supervisor's information so that I could express my appreciation. Mr. Werner then elaborated humbly that he was the owner of the company, and spent even more time speaking with me. When Mr. Werner left my room that Friday, it was nearly 6 p.m.
As a result of the fit and support of the brace, I am able to do the physical therapy more effectively. I am truly grateful for the caring and professionalism from Mr. Werner, and will always remember the kindness and time he afforded me.

Our physical therapist referred our daughter to Marc and her initial visit was at her office in Ronkonkoma. Our first image of Marc was that he was professional, courteous, knowledgeable, and has a lot of patience. Overall it was a very good first impression. Our experience at Marc’s office was a positive one. His staff is kind and professional and his office is neat and clean. I’m impressed that my daughter was able to pick out a pattern for the brace. She was made to feel involved and special during the order process. Marc even went out of his way to put gloves on her while he was casting her. When we were first told that she needed braces, we thought they would be large, cumbersome and unattractive and that wasn’t the case. The braces have a wonderful custom fit that exceedsour expectations. When we needed adjustments to the braces, we were accommodated in a timely fashion, without any problems We also want to add that we're appreciative of the great referral we received to her current Pediatric Physiatric group through Marc and we're very grateful. We recommend LIO&P to anyone who has a child in need of bracing.

Initially I came for my consultation at Long Island Orthotics and Prosthetics because I was stumbling and unstable with my older orthotics. I have been wearing orthotics since the age of 2, I am now 33. I left feeling stable and secure. They are the most stylish orthotics I have had in my life. They help me to stand straighter and not make me feel as tired when I walk. They have a special lining that helps me keep them clean and fresh smelling. The people provide great customer service and are extremely friendly. Marc and his staff are like family and I consider us united for life. I highly recommend Long Island Orthotics and Prosthetics to meet all of your Orthotic needs.
