Ingenuity Engineers

was formed over thirteen years ago by David F. Green and Brian S. Hessinger to service a growing and changing Orlando market. Mr. Green and Hessinger’s 60+ years of combined experience in the design and management of building engineering systems allowed them to build a firm competent in all aspects of facility mechanical, electrical, plumbing, low voltage and fire protection design.

Mr. Green and Mr. Hessinger recently decided a change was needed to better service Ingenuity’s clients. They partnered with Mr. Jody McKenzie P.E. to bring an owner/developer’s perspective into the mix. The new partnership brings additional experience and allows Ingenuity to make project/company decisions without the influence of any outside ownership.

Ingenuity Engineers is licensed in 35+ states and the Caribbean. We have experience working in Asia, Europe and the Middle East. The experienced and diverse Ingenuity team is committed to providing a quality proactive engineering solution that is tailored to our clients’ needs and budget.
