Our personal experience underscores every relationship we build with a patient. We understand the mental and physical hurdles in an amputee’s journey to their new life with their new prosthesis. From pre-op to complete fit, Shamrock Prosthetics builds a relationship based on trust, compassion, belief and encouragement with each patient on their unique path to recovery. We provide innovative technological solutions for the customer in this antiquated industry and underscore our relationship with the highest caliber of customer.


We are changing the standard in patient care, clinician relations and custom prosthetics for amputees.

Traditionally, the prosthetics industry is reactive industry where a patient starts the prosthetic conversation post surgery.

Shamrock Prosthetics does it differently: we establish a relationship pre-surgical with the patient and the surgeon to maximize the possibility of long-term functionality. Our custom fabricated prosthetics takes into consideration each patient’s limb size, shape and structure as part of our pre-op phase.

Following surgery, we remain at a patient’s side every step of the way throughout the healing process and fitting phase to restore or increase pre-injury functionality. Likewise, if a patient is not able to travel to our office, our clinical manager will travel to the patient’s home or rehabilitation facility to accurately fit for a custom prosthetic.

Just as important, because we have personal amputee experience, we understand the frustration and other mental challenges associated with recovery and work closely with each patient to restore and encourage a positive attitude throughout.

A 2001 accident and 13 surgeries left Steve Ehretsman, a Division 1 athlete and founder of Shamrock Prosthetics, with a below-knee amputation. His experience with the pre- and post-op patient care, prosthetic options available and general mental wellness challenges associated with recovering from the accident ultimately drove his decision to approach prosthetic management differently.

On May 8th 2015, Ehretsman launched Shamrock with the guiding conviction to approach an amputee and surgeon relationship differently than he experienced and to develop technology-advanced prosthetics that offered patients full functionality.

Today Ehretsman and his team meet with patients prior to surgery and weekly throughout the recovery process. Likewise, Shamrock fabricates all of its custom prosthetics on site in its 3,400 facility in Athens, Georgia.


We continue to grow and build our family of Shamrock Prosthetics patients and referral sources. In 2019, we will be renovating our Athens office to add another 2,000 square feet.  This will bring the total of 5,500 square feet.  The growing demand for Shamrock Prosthetics unique patient care will have us launching offices around the State of Georgia in the near future.
