About the Firm
Led by a registered engineer with three decades in the field.
Dave Madary, a registered professional engineer in Pennsylvania and Maryland, owns and leads Madary Engineering & Design, LLC. The firm was established in 2023, leveraging 30 years of industry experience to provide land planning and approvals for select clients primarily in the South Central Pennsylvania region. Madary Engineering & Design is committed to excellent client service, quality, and practical and attractive design.
As a seasoned civil engineer and project manager, Dave has led numerous site master planning and land development projects across sectors, managing work through every phase — due diligence, concept, land development, project approvals, and construction drawings. Project success relies heavily on the municipal approval process, so a priority is establishing and maintaining strong working relationships with municipal staff to keep projects moving efficiently.
Certain projects call for subconsultant support — site survey, traffic impact studies, geotechnical infiltration testing and characterization. Madary coordinates that team as needed, routinely collaborating with owners, contractors, attorneys, architects, surveyors, and other engineering disciplines to keep design and construction seamless.
- Provide a high level of technical expertise on every engagement.
- Lead all phases of site planning essential to the client.
- Collaborate closely with reviewing agencies and all project stakeholders.
- Establish a project schedule that works for the client — and keep the process moving.
