Marko Kosta

Marko grew up skating the streets of NYC in the late 1980’s and through the 1990’s. He picked up skating at age 14 and quickly fell in love with the exhilarating feeling of riding a skateboard and learning new tricks. He competed between the ages of 18-22. He earned his Bachelor’s degree in Business Administration from Pace University in 1999 and worked as a marketing executive for many years, prior to founding SK8 GYM, Corp.  
He has lived in the San Francisco Bay Area for 20 years, where he raised his two sons and volunteered with various youth community programs for 15+ years. During that time, he has instructed students age 5+ how to safely ride a skateboard among other activities. He now splits his time teaching between SF Bay Area and Los Angeles area.
