James Guarino


James V. Guarino is the Chairman of ERG Commercial Real Estate and the former co-founder of Extreme Realty. He started his career in 1989 as a salesperson at John Anthony & Associates during a crashing market and saw the number of agents in his office decline. Despite the difficult period, James became the biggest producer in the office at age 23 and an expert in distressed sales, selling non-performing mortgages and REO portfolios for numerous banks, the RTC and the FDIC.

In 1993, he founded JG Capital, JVG Management and Extreme Realty. This was his first step toward fulfilling his desire to create a full-service investment firm. During this time, he made personal investments in real estate and mortgage portfolios while specializing in quiet, off-market deals. In 2009, James utilized the downturn in the market to streamline the companies. James then formed the ERG Finance Division, a mortgage brokerage and direct capital services provider, thus completing his goal of creating a full-service investment firm.

When he is not closing deals, James loves to spend time with his wife, children and animals. He also enjoys boating, snowboarding and outdoor activities. He is a member of NAR, REBNY and the Progressive Era Club. Mr. Guarino is also as an avid member of the Sands Point Golf Club and the Havana Club in Long Island, New York.
