Emil Gamidov


The Founder

Emil Gamidov founded ONYX Health Club 24/7 in 2016. Prior to ONYX, Mr. Gamidov operated numerous other successful ventures. In early 2018, he decided to shift his focus to his true passion, ONYX. As a result, ONYX has grown at an exponential rate.

His fitness journey began right out of high school when he was hired at a local Bally Total Fitness facility in Cleveland Heights, Ohio. It was a summer part time job for him just to save enough money to fix his car so he could attend Cleveland State University. He would roller blade to work and prior to walking in, he would toss them in the bushes. He was too embarrassed to be seen rollerblading to work.

Despite the challenges he had to overcome, he stood out from his co-workers immediately and was promoted quickly to General Manager. He successfully turned around numerous Bally Total Fitness clubs in Northeast Ohio in the mid to late 2000’s. He attributes his innovations and the success of the ONYX franchise to the expert mentoring and upbringing that he received during his career.
