"For the last year, Keith Summers of Colliers International (Tysons Corner, VA) has been representing Silverstone Healthcare Company in its quest for in-fill, high-quality sites for development of private-pay assisted living and memory care facilities in the greater Washington, DC market. Our quest has taken us from the northern reaches of Montgomery County in Maryland on down through Fairfax, Loudoun and Prince William Counties in Virginia. Using his extensive knowledge of the markets and a well-connected network of property owners and other real estate professionals, Keith has identified roughly two dozen parcels which we have collectively culled down to six viable development sites. Throughout the process, Keith has been proactive, diligent, responsive and has consistently shown considerable ingenuity in sourcing attractive development sites."
