Mary Cook

Mary Beth Cook is a former Calvert County Government planning and zoning executive. Public records and county announcements identify her as Director of Planning & Zoning for Calvert County, Maryland, not as an angel investor. The available sources do not verify any angel investing activity, startup portfolio, investment check size, or seed-stage investment role.

Cook began working for Calvert County Government on April 19, 1993, as an engineer in the Department of Public Works and was promoted to project engineer. In 2008, she moved into the Department of Planning & Zoning as deputy director and zoning officer. On January 6, 2020, the Calvert County Board of County Commissioners appointed her Director of Planning & Zoning, succeeding Mark Willis, who became county administrator.

Her work included master planning, the Calvert 2040 Comprehensive Plan, zoning ordinance text amendments, zoning code enforcement oversight, and supervision of inspections and permits functions. County and local press sources also describe her role in guiding sustainable development and broader planning initiatives in Calvert County.

Cook holds a bachelor’s degree in civil engineering technology from the University of Pittsburgh. She graduated from Leadership Southern Maryland in 2017 and Leadership Maryland in 2019. Calvert County recognized her more than three decades of service before her retirement, which was set for January 10, 2025; Jason Brinkley became Planning & Zoning Director effective January 11, 2025.

• No verified investment thesis, angel-investor profile, portfolio, check size, or startup-stage focus was found in the sources reviewed.
• The stub label “Angel Investors” is not supported by the public sources found; the verified record identifies Cook as a Calvert County Government planning and zoning official.

• For companies interacting with her office during her tenure, relevant issues were zoning compliance, permitting, inspections, land-use approvals, comprehensive planning, and development review, not venture financing.
