Don Penn has been involved in the engineering community since 1978.

During his early career, Don developed relationships with both national retail and education clientele across the United States, which is still maintained today. In September of 1991, Don formed Don Penn Consulting Engineer (DPCE) to better serve these clients.

In 1992, Birdville ISD turned to DPCE for engineering support and energy conservation techniques. DPCE became a leading pioneer in Geothermal Heat Pump HVAC Systems and gained interest from many other education clients across the country.

In 2003, Image Engineering Group, Ltd. was established as a sister company to DPCE. Together, both companies are comprised of over 30 dedicated engineers and designers. IEG & DPCE require all of their engineers and designers to be well versed and knowledgeable in all aspects of MEP design. This level of performance maximizes coordination, efficiency and innovation in each project.
