Mackin Engineering Company (Mackin) has been a provider of engineering and consulting services since 1960. Our firm serves a broad array of public and private sector clients, providing innovative solutions for all phases of a project, from conception to attainment.  Italo V. (Ody) Mackin, PE (act. – ret.) (the company’s founder and Chairman of the Board) is joined by his son, Dean I. Mackin, CEO and Thomas E. Riester, PE, President in overseeing our 80+ multi-disciplinary staff, which includes dedicated professionals in the fields of civil engineering, construction inspection/construction management, traffic engineering, landscape architecture, planning, surveying and more.

Shortly after graduating from high school, Ody Mackin joined the U.S. Army during World War II, where he served for 33 months, 27 of which were in the Pacific Theatre of War. 

His overseas tour of duty began in Australia and ended in Osaka, Japan before returning home. He then matriculated to Carnegie Institute of Technology (now CMU) where he received his Bachelor of Science degree in Civil Engineering.

Following a decade of employment with the consulting engineering firm of Richardson Gordon and Associates, he opted to utilize his experience in bridge and highway engineering and joined a fellow colleague (George Davic) in forming an engineering and surveying firm in 1960. The partnership of Mackin and Davic was dissolved in 1963 at which time Mackin Engineering Company became a corporate entity in Pennsylvania.

The three year span of Mackin and Davic began the development of bridge and highway design with then Pennsylvania Department of Highways, together with engineering and surveying services for other clients, some of which are still being served today by Mackin. This fact illustrates further evidence of our quality services and commitment to client satisfaction.

In 1978, Mackin expanded our offerings by providing Construction Inspection/Construction Management services. In 1985, Mackin pursued and secured one of the first state Bridge Inspection contracts in Pennsylvania. These services have become important and significant aspects of the business. Throughout the early and mid 90’s, Mackin expanded its list of services to include Community Planning, Landscape Architecture, Environmental Services, and Traffic Engineering.  Mackin created this team of multi-disciplinary professionals to better serve our clients and offer greater diversity. During this time, we added a second office location in the Harrisburg Area of Pennsylvania, allowing us to successfully provide services throughout Pennsylvania and beyond.

Mackin’s commitment to clients is only surpassed by its commitment to our employees.  A good measurement of that dedication is the number of employees who have been with the company throughout the years – a few have even been with the company for over forty-five (45) years; while more than twenty-five (25) employees have dedicated their careers spanning over twenty (20) to thirty-five (35) plus years.  Throughout the highs and lows of the company, Ody Mackin has prided himself on never having missed a payroll; providing his employees with excellent health insurance benefits; and having a successful 401(k) plan.  This dedication to his employees has made Ody the respected leader he is and has made our company the successful business it is today, which has allowed us to extend that commitment and respect to the clients we serve and the many projects that we’ve completed.

Today, Mackin Engineering Company looks forward to growing by meeting the increasing need to maintain, upgrade, and expand our aging infrastructure system in Pennsylvania and beyond. We stand at an important crossroad in our state and nation. Mackin has been truly blessed to provide services for our clients for over 50 years. We are truly excited and optimistic about the opportunities for the next 50!
