Since the launch of the BioPark Initiative in 2003, the BioPark has grown to include nearly three dozen companies with more than 1,000 employees. Looking out a fifth-floor window of BioPark Building One, BioPark Senior Vice President Jane Shaab pointed out other BioPark facilities, such as the Maryland Proton Treatment Center, the Maryland Forensic Medical Center, the newly added Lion Brothers Building, and the construction site where work has begun on BioPark Building Three, a facility that will double the number of BioPark employees.
