Gregory D. Kimmelman | Director of Preconstruction

Director of Preconstruction for Seminole/Stiles

As Director of Preconstruction, Greg holds executive-level responsibility as the head of the preconstruction department. Reporting to the Senior Vice President, he manages and mentors a team of project executives and oversees all preconstruction workload efforts to ensure quality, accuracy, and timeliness. Greg also makes sure that peripheral considerations are addressed in all construction budgets, such as adjacent properties, site constraints, and other technical means and methods not directly associated with the projects themselves.


Greg has been involved in many commercial assignments with roles in both preconstruction and construction, and has worked on commercial, office, retail, healthcare, automotive, emergency operations, residential and call center projects. He began in the field as an Assistant Superintendent, then became an Estimator / Field Assistant before joining a major construction company as an Estimator and Project Manager. Prior to joining Stiles, Greg established the South Florida office of a premier tilt-up concrete specialty contractor. He believes in listening closely to clients’ needs and then translating what he hears into action, finding workable solutions that will satisfy customers.
