Rockville Soccer, the retail home base for MSI and a long list of local soccer clubs, has moved into larger quarters on the second floor of Wintergreen Plaza. Owner Hrant Tatarian, who runs a small chain of soccer stores in the D.C. area, says his 23-year-old business had outgrown its cramped space at the Sunshine Square Shopping Center further south on Rockville Pike. The new store, near Gold’s Gym and Adventure Theater MTC, offers 4,000 square of footwear, uniforms and soccer equipment. “We wanted to have concept shops for Nike and Adidas like you’d expect to see in a Dick’s or a Nordstrom,” Tatarian says. “We really needed the extra room.”
