Senior Personnel

With a services portfolio of well over 100 properties throughout the greater-Washington area and over 600 personnel to supervise, our Executive Team depends upon a diverse group of senior-level individuals to keep Zalco's operations running smoothly.

Property Management (Commercial & Residential)

Dennis Freeman, has over 26 years of mixed-use residential/commercial management experience, over which time he has enjoyed a positive working relationship with numerous developers and all types of new and existing common-interest realty associations. Dennis joined Zalco in 1985 after being Homes Corporation Manager for Kettler Brothers, Inc. and in that capacity functioned as the chief liaison between that company and The Montgomery Village Foundation, Inc. Prior to these positions, Dennis assisted a busy and varied three-attorney land-use legal practice while still in graduate school in San Francisco. As Zalco's longest-tenured property manager, he now manages what is likely our highest-profile residential portfolio, with seven properties requiring a total of 145 service personnel, utilizing an aggregate annual budget of over $15 Million. One of his strongest attributes is his ability to coordinate long-term capital improvement project planning and implementation. He holds Bachelor degrees in both Psychology and Social Statistics from Carson Newman College, and also earned his MPA from Golden Gate University with a concentration in Urban, State, Federal Governance and Finance.

Donald J. Perper, one of Zalco's four Vice Presidents in property management, supervises an experienced team of property managers while also carrying his own portfolio of high-end residential condominiums and commercial office clients. When he joined Zalco in 1998, Don had over 15 years prior management experience with hotels and large luxury high-rise condominiums. During these tenures he supervised the start-up, renovation and conversion of several hotels, and developed and programmed a variety of property-management databases. Don has also been an active member of the Washington Metropolitan Chapter of the Community Associations Institute (CAI) and in 1997 received that group's prestigious 'Rising Star' Award and its 'Community Association of the Year' Award for one of the properties that he managed. He has chaired or served on several CAI committees and is an occasional author for certain real-estate periodicals on matters of current market interest. Don also holds the highest professional designation that can be earned by a community manager - the PCAM (Professional Community Association Manager) designation, as well as the CMCA (Certified Manager of Community Associations) designation.

Mark S. Petrusic, is Vice President of Zalco's busy and expanding Commercial Division and has over 20 years of property-management experience.

His responsibilities include meeting regularly with property owners and tenants, approving monthly financial statements, coordinating transition of space with tenants and brokers, monitoring expenses, preparing and administering budgets, inspecting properties, administering all aspects of lease performance, and monitoring third-party contractor performance (on-going maintenance, tenant build-out and capital improvements).
