Robert Grimes knew at an early age that he enjoyed helping around the house – working with his hands. At age 17, Robert’s mother wanted him to install crown molding in the living room. He jumped at the opportunity, and once he finished, he knew then what he wanted to do with his life.
After graduating from Catonsville Community College, with a degree in Construction Management and Design, Rob accepted a position with a Ryan Homes. He began designing and building homes and later began to manage multiple projects – interacting directly with customers.
