Design Professionals

What Design Professionals does

Design Professionals, Inc. (DPI) is a Connecticut-based professional services firm founded in 1986 that delivers integrated civil engineering, land surveying, landscape architecture, planning and development, and traffic engineering services across Connecticut, Massachusetts, and Rhode Island. From its South Windsor headquarters, the firm supports private-sector developers, commercial and industrial clients, educational institutions, and public-sector/municipal customers through both project-based engagements and on-call contracts (including work for the Town of South Windsor, Town of Hamden, the State of CT/University of Connecticut, and the United States Fish and Wildlife Service). Core service capabilities span the full site development lifecycle — feasibility studies, site master plans, site/civil design, stormwater and utility design, ALTA/NSPS and boundary surveying, construction stakeout, landscape and wetland mitigation design, and traffic impact and roadway design — executed by a multi-licensed team of civil engineers, land surveyors, landscape architects, and planners.

The firm's technical stack centers on industry-standard civil and surveying tooling rather than proprietary software: AutoCAD Civil 3D, HydroCAD, GPS Virtual Reference Network (VRN) equipment, robotic total stations, digital surface modeling with TIN surfaces, and photogrammetric mapping for aerial projects. Pricing is project-specific, quoted per engagement or through municipal on-call arrangements rather than standardized tiers. The go-to-market is direct and relationship-driven — staff present site plans to local regulatory boards, work on referral and repeat business from a base of 5,000+ completed projects in 225+ New England communities, and add more than 125 new projects annually.

Design Professionals is privately held and family-controlled, with founder/Founding Principal Peter DeMallie serving as President & CEO following a 2022 succession from Anne DeMallie (CFO 1986-2008, CEO 2008-2022). The leadership team is tenured, with the VP of Land Surveying, Director of Surveying, and Deputy Director of Surveying each carrying 35-40+ years of experience. DPI holds Connecticut Small Business Enterprise (SBE) certification, employs LEED-accredited professionals, and maintains affiliations with regional economic development organizations (New England's Knowledge Corridor, Connecticut Airport Authority, MetroHartford Alliance). No institutional investment, private equity, or venture backing is indicated; the firm operates as an independent, self-sustaining professional services practice.
