Electrical engineering firm will augment Coffman's multidiscipline services in Los Angeles

Jack Arslanian, President/Principal, N.A. Cohen Group

Multidiscipline engineering consulting firm Coffman Engineers, Inc. (Coffman) announced today they reached a definitive agreement with N.A. Cohen Group, Inc. (N.A. Cohen), an electrical engineering firm, to join Coffman. The merger is planning to close in December 2021.

Coffman and N.A. Cohen have many of the same clients and an established working relationship since 2010. N.A. Cohen's capabilities and portfolio complement Coffman's existing work and partnerships in LA, particularly in healthcare, hospitality, higher education, and housing. Through discussions beginning in 2019, both firms agreed that joining forces would benefit clients and provide opportunities for employees.

"Our growth in the LA area calls for outstanding electrical engineering talent to expand our multidiscipline services," said Jonathan Wirthlin, Coffman's Vice President, Managing Principal, LA-OC Region. "N.A. Cohen is that partner. They have built a respected firm in LA, and we are fortunate to have them bring that legacy to Coffman to establish our electrical department."

This merger is a strategic fulfillment of Coffman's plan to establish an electrical engineering department in Los Angeles. Coffman's LA offices currently do not offer in-house electrical engineering services. The addition of N.A. Cohen will become the LA electrical engineering group.

"N.A. Cohen has been motivated by a continued drive for innovation, insistence on excellent work, and detailed attention to providing clients outstanding services, and we found a partner in Coffman that has the same level of care," said Jack Arslanian, N.A. Cohen President/Principal. "We look forward to joining them."

Jack Arslanian, PE, N.A. Cohen President/Principal, will join Coffman as a Principal Advisor, and Youssef Matta, PE, RCDD, CTS, N.A. Cohen Executive Vice President, will join Coffman as a Principal. In addition, six N.A. Cohen employees will become Coffman employees. They will all move a short distance to Coffman's Encino office.

"We are selective in the leaders and firms we partner with and are committed to finding opportunities that benefit our clients and team members," said Dave Ruff, Coffman's CEO/COB. "As I got to know Jack, Youssef, and the N.A. Cohen team, I was excited at how complementary our work, values, and culture are. I am confident that we will be successful together."
