John Stemlar, JD, MS - Principal and Managing Broker
John Stemlar has over 35 years of professional real estate experience. He began his career as an attorney with a major law firm, representing commercial real estate investor, developer, and lender clients in a wide range of transactions. This fueled John’s interest in real estate investment, which led him to pursue a master’s degree in Real Estate Finance and Investment. After earning his master’s degree, John spent 10 years in commercial real estate investment, buying, selling, and financing multi-million-dollar office, retail and apartment projects. While assisting friends with the purchase of a home, John recognized an opportunity to offer homebuyers and sellers a higher level of skill, sophistication and representation integrity than is typically encountered in residential real estate. The satisfaction of helping clients succeed in their most important personal and financial undertakings motivated him to make the move from commercial to residential real estate. John started a residential brokerage business in 2003 and co-founded Sage in 2007. As a real estate broker, John has been involved in hundreds of residential transactions across north-metro Atlanta. He is also an active real estate investor. John specializes in single-family homes, townhomes, and condominium properties.
