Acela stands for speed and efficiency.

Founded Nov, 4, 2014 by Daniel Witzak, P.E., Acela has grown to include a trusted staff of 18 full-time and seven part-time employees who provide coordinated in-house services in a way that translates to speed and efficiency for the client.

Witzak founded Acela with the intent of creating an engineering firm that is both client-focused and employee-focused. We believe in listening to the client’s needs, being responsive and communicating with clients to keep them informed.

Acela believes in treating its employees well and this translates to an enthusiastic and productive staff. With our technology infrastructure, most of our staff is able to enjoy working from home two or three times a week.

Acela has some of the most experienced architectural and engineering professionals in the Lehigh Valley. Our project managers have more than 20 years experience in the engineering profession.

Dan is a project management professional (PMP) and a registered engineer in Pennsylvania, Massachusetts, New Jersey and New York.

In August, 2016, Chris Geary joined the firm. He is a certified professional in Erosion and Sediment Control (CPESC), Storm Water Quality (CPSWQ) and Municipal Stormwater Management (CPMSM), and a registered engineer in Pennsylvania, New York, New Jersey, Ohio, North Carolina, Texas, Florida and Wyoming.

In January of 2019, Acela included architectural services, making it one of the few firms to offer both engineering and architectural services.  In January of 2020, Joseph Herman, R.A. joined Acela.  Joseph has over five years of experience working with various medical centers across the country and over 25 years of experience in various architectural services.

By combining all these services under one roof, Acela’s speed and efficiency translate to lower overall costs for clients.  Acela is headquarters in Allentown, PA with satellite offices in Marlton, New Jersey, Lagrangeville, New York, and Cleveland, Ohio.
