Our Backgrounds

Scott & Laura St. John

LeisaGibson_JMac_0045With a background in business and entrepreneurial ventures, Scott and Laura have experience taking a proven business model and successfully replicating the concept for expansion at a local and national level. After rolling out a technology education company nationally and partnering with Discovery Communications (Discovery Channel/Discovery Kids), Scott and Laura decided it was time to follow their passion for fitness and healthy living.

They turned to the expert in the field that they met through their own personal training experiences as a client of Johnny Mac in Breckenridge, CO. They approached Johnny early in 2012 with a proposal to partner in a business venture to launch a fitness business in the Denver area.

By spring 2012, they launched their first location and chose to name the business after the person who designed a unique formula for group personal training well before others started this concept in the fitness field – Johnny Mac Fitness.
