Joseph Gray, P.E.



Marlene Myers, R.A. NCARB


Educated as a civil engineer with a concentration in Structural Engineering, Joe Gray has a solid foundation in building design. His detailed design knowledge, coupled with his extensive construction experience, provides Ashlar Architecture & Engineering with an immeasurable wealth of practical, real-world experience.


From 1980 to 1991, Gray worked in construction and construction management. Notable projects include: Ross Park Mall, Mine Safety Appliance Headquarters and Pittsburgh International Airport Mid-Field Terminal.


In March 1997, Gray founded Gray Engineering Corp., an engineering consulting firm which quickly grew into a formidable engineering firm, providing full engineering services and specializing in land development planning and design. Warnick Company, which had been in business since 1945, was purchased by Gray Engineering Corp. in 1999, forming Gray Warnick Engineering. Another transition occurred in 2005 when Gray Warnick was purchased by The Gateway Engineers, Inc., which Gray was a partner in until 2009 and for which he continues to act as a consultant for.


In a parallel path to the consulting work, Gray pursued his love for building design and renovation. As a young man in high school he designed and helped build three of the family homes. Since marrying Jacquelyn Young in 1990, he designed and they built three of their own homes.


As the need for space to house his consulting firm grew, Gray found himself involved in more with real estate projects. He and Jackie bought their first commercial property in Mount Chestnut and made it the office for the engineering company. To expand the company, they purchased their first downtown Butler property, the Independent Order of Odd Fellows building on Main Street. This building was too large for the engineering company; so began the road to renovating and leasing commercial space. Since then, Gray has purchased and renovated several downtown properties, including the building directly behind the I.O.O.F. building where Ashlar Architecture & Engineering resides.

Marlene Myers has considerable experience in commercial and residential design. For the first thirteen years of her career she worked in Virginia for the Lessard Group, a firm that specialized in residential design, ranging from single family homes to high-rise, mixed-use developments. Myers gained experience in the residential market as a project manager, leading her team to complete many successful projects in the eastern United States.


In 2005, Myers and her young family moved back to Western Pennsylvania. Two years later, in 2007 she joined 4-Most Group, Inc. Architects as a project manager, and later became a registered architect. There, she expanded her knowledge of commercial architecture by working on a variety of projects, including: offices, religious projects, restaurants, and institutional facilities. During this time, she and her husband dismantled an old barn and relocated it to a new home site, creating their unique family home.


In 2018, she became a partner at Ashlar Architecture & Engineering where she continues to provide comprehensive design and architectural services to a variety of clients.


She is involved in several local organizations, including: Butler County 4-H, where she serves as a leader; Butler Gymnastics Parents Organization where is a Board Member; and Mars Centennial Lions Club where she is a Charter Member.
