Pennoni Associates Acquires Patton Harris Rust & Associates

Philadelphia, PA; Chantilly, VA — January 3, 2011 — Pennoni Associates, an ENR Top 115 engineering, design and consulting firm headquartered in Philadelphia, has acquired Patton Harris Rust & Associates (PHR+A) headquartered in Chantilly, Virginia. Pennoni is pleased to announce the addition of the 175 staff members and seven offices of PHR+A to its family of professional, technical and administrative personnel. Pennoni has been providing multi-disciplined consulting engineering services from offices in the Northeastern United States since 1966, and is now proud to incorporate the PHR+A offices in Maryland and Virginia into its base of operations.

PHR+A was established in 1952 as a professional engineering and land surveying firm in Northern Virginia. They have a long tradition of providing engineering services to a variety of clients throughout the Mid-Atlantic Region. PHR+A’s professional staff include telecommunications and utility engineers, surveyors, planners, landscape architects, and environmental specialists. Their staff and services will complement and enhance those offered by Pennoni Associates nationally and internationally.

"Pennoni Associates is both pleased and honored to welcome PHR+A into our firm," stated Pennoni Founder and Chairman C.R. "Chuck" Pennoni, PE. "PHR+A has an excellent professional reputation of providing quality engineering services with honesty and integrity for over 60 years while providing a very welcoming place to work. We are confident that this marriage will enhance opportunities for both our clients and our staff, and enable Pennoni Associates to provide a broader range of engineering services both nationally and internationally."

The addition of PHR+A and their seven offices in Maryland and Virginia enhances Pennoni’s size and geographic reach. Prior to the acquisition, Pennoni had 775 employees in eight states providing engineering, design and consulting services. Much of Pennoni’s long-term success can be attributed to the excellent client service they provide by having offices strategically located to serve both national and international clients, a business model shared by PHR+A.

"We are excited about the increased opportunities for both our clients and our staff," said PHR+A Chairman Thomas D. Rust, PE, AICP. "By leveraging the additional services and resources Pennoni offers, we will be able to increase our ability to serve the clients we have valued over the past 60 years. Our staff will have opportunities to further develop and contribute their expertise to an even wider variety of challenging projects. Our two firms share the same core values of ethics, professionalism, and client service."
