“Leadership and learning are indispensable to each other.”
-John Fitzgerald Kennedy

Like President Kennedy, we at Rhea believe: “One person can make a difference and every person should try.”  While the leaders at Rhea draw from a deep knowledge base gained through years of experience, we also recognize that the best leaders are avid learners.  We teach by example.  We choose employees wisely, train them well, and trust them to face challenges head on.

Our leaders guide our team to approach projects from a big picture point of view.  This method often brings resolution to our clients’ problems in a more timely and cost effective manner.

With decades of experience, the professionals at Rhea stand at the intersection of tradition and innovation. We are committed to excellence in technical and organizational management and combine real world experience with the latest software and hardware to deliver unparalleled, sustainable solutions.  Our team leaders include:

Marcella G. Johnson, PE: President
