Our full-service organization invests in a range of commercial property types – with a focus on value-added potential – and we are known for our expertise in Brownfields redevelopment and condemnation proceedings. Our vision and leadership working in conjunction with municipalities, state agencies, contractors, engineers, architects and brokers have led to the successful transformation of dozens of underutilized properties into valuable real estate assets.
