John Kalamaras
Founder and President

John Kalamaras is Founder and President of RealSource Group. John launched RealSource Group in 1991, a commercial real estate firm specializing in international tenant representation for niche operators in the retail and healthcare industry. As a pioneer of tenant representation, he led the initial integration of health and fitness tenants into retail properties. As the business started to plateau, John decided to make a paradigm shift in data and workflow management, transitioning a conventional business model to a new technology-based platform.

After a year of development, he leveraged this proprietary tech-forward platform to scale production throughout North America and manage a pipeline 10x its prior production level with less overhead. To validate this business model, RealSource is most notably recognized for its outsourced expansion efforts of the most successful health club chain in North America, helping that tenant grow from 35 regionalized locations in the western United States to over +700 units throughout North America, which included greenfield development and acquisitions of various fitness chains. Career transaction volume of +800 deals in 54 different metropolitan areas.
