A New Path Forward
Established in 2004, RA Consultants is a private, independent firm of engineers, designers, surveyors, and professional construction inspectors working across every aspect of the infrastructure environment. Together we help our clients solve their most complex water and land challenges – turning ideas into tangible reality as we strive to find a better way and shape a new path forward.
"We offer the skills and experience of a larger organization but with the flexibility and efficiency of a smaller independent firm," states Founder, John Allen.
With the foundations built upon partnership and an ethos of hard work and integrity, RA Consultants has become a leading provider of infrastructure management and technical consulting services in Cincinnati, Dayton, Columbus, and Louisville.
