The Professional Dynamix Engineering Team

Innovators respond to visionary leadership, and Dynamix is proud to have that kind of leadership at every level of our organization. Meet some of the experts at the helm of each division:

Eugene Griffin, PE, LEED® AP BD+C

CEO and Principal-In-Charge of Marketing and Business Development and Healthcare

The CEO of Dynamix, Gene also serves as the Principal-in-Charge for the company. With an A.A.S., a B.S. in Mechanical Engineering Technology and more than three decades of experience in the industry, Gene monitors the progress of each Dynamix project, provides guidance to engineers, leads the implementation of sustainable green building design, collaborates with other principals to provide appropriate solutions for projects, oversees development and the production of deliverables, and, most important to him, develops lasting relationships with clients that extend long after a project is complete. Under his leadership, Dynamix has designed a Pebble Project, engineered the first OFSC LEED® silver certified school for Cincinnati Public Schools and is now in the process of designing many more LEED® certified projects. Gene’s project experience includes work with the Ohio Department of Transportation, the City of Columbus, as well as nearly a dozen hospitals and medical facilities, public schools, recreation facilities and municipal facilities.

It’s hard to imagine a guy who loves Dynamix as much as Gene does stepping away from the office once in a while, but when he does, he can be found on the golf course or training with weights.

Lee Anne Dye

Healthcare Division

Lee Anne attended Ohio University and has been in the engineering industry since 1979 and with Dynamix since 2005, where she serves as a Senior Associate, Project Executive and Healthcare Design Group Leader. Lee Anne’s decades of experience in engineering consulting, construction administration and project design have given her a broad design skillset, which includes lighting, general power, normal and emergency power distribution, utility coordination, fire alarm systems, nurse call and other low-voltage systems. Her project management work includes contracts, owner programming, and communication processing between owner, architect and construction team. At Dynamix, Lee Anne gets to put her skills to use on high-caliber projects such as the Lexington Medical Center, the Dublin Methodist Hospital, Nationwide Children’s Hospital, Cincinnati Children’s Hospital, the University of Illinois at Chicago and other medical centers, educational facilities, retail spaces, medium/maximum state detention campuses and high-rise living facilities.

When she’s not busy overseeing projects from pre-planning to ribbon-cutting or designing sophisticated systems for clients, Lee Anne can be found cruising through the Hocking Hills area on the back of a Harley with friends or helping out family members on any home project that involves paint and power tools (sadly, her family has yet to request a system evaluation or utility coordination, otherwise she would gladly help out with that as well).
