Dr. Hatrak

Dr. Hatrak is affectionately known in the circles of professional athletes as a “Miracle Man”, “a Genius” for the results he has been able to deliver in the area of sports injury treatment and prevention.

A man passionate about eliminating chronic bio-mechanical injuries, Dr Michael Hatrak has been in practice for over 31 years specializing in sports medicine and performance. He received his Doctor of Chiropractic in 1976 from New York Chiropractic College (Columbia Division). In 1979, he was a professor at Pennsylvania Chiropractic College while maintaining a private practice in Cherry Hill, New Jersey.

After years of research Dr. Hatrak came to the realization that Chiropractic care alone wasn’t enough to deliver the corrective care needed for professional athletes and the large increase of the “weekend warrior” crowd. Realizing there was a missing piece to the methods of treatments Dr. Hatrak discovered the solution with a man by the name of John Patterson. An extraordinary individual with an uncanny ability to see interrelationships within the bodies bio-mechanical structure, Mr. Patterson shared Dr. Hatrak’s passion for finding the missing link. Subsequently, along with Brian Glotzbach, Dr. Hatrak developed the foundation of SRT (Synergy Release Therapy).

Dr. Hatrak owes his success to his friend and mentor John Patterson who is the founding developer of this unique, one of a kind therapy that allows athletes to perform at their optimal level.

In the last 20 years the SRT team of doctors and practitioners have worked with over 400 NFL players from over 27 teams as well and pro athletes from all sports, keeping them at the top of their game.

Dr. Hatrak

Dr. William Cohl brings to Synergy Release Sports a personal and passionate interest in Applied Kinesiology.  Dr. Cohl’s interest in this specialty stems from a long, personal journey of finding health in his own life.  He struggled with Chronic Fatigue Syndrome which after no relief led to depression and dropping out of chiropractic school.

Hearing about a chiropractor who practiced something called Applied Kinesiology, he decided to try it out of desperation.  After the doctor listened to his symptoms, he explained that Applied Kinesiology deals with the body as a whole by dealing with the energy flow in the body.  Illness comes about when the “energy” is blocked by physical, chemical, or mental stress.  He also pointed out that Chinese have practiced a similar form of therapy for centuries and it continues to this day.

After multiple treatments where results were up and down on the grid, he experienced a major breakthrough with a major physical reaction to the treatment.  Initially this brought a very strong sensation in his body and then extreme fatigue which is often a normal reaction to releasing a blockage in energy.  By the afternoon, he felt much better and his energy soared.  This result turned out to be permanent and has lasted for about 10 years.  This experience determined his path in life.  He returned to school, got his degree as a doctor of chiropractic and began concentrating on the area of Applied Kinesiology.

Helping people regain their health has been incredibly rewarding but helping people regain their energy to live their lives fully will always be most satisfying.

Dr. Cohl received a B.A. in Biology from Mansfield University in 1993; received his Doctor of Chiropractic degree from Life University in Marietta, GA in 2001 and attended International College of Applied Kinesiology in Atlanta, GA in 2004.
