About Omar Kassem, General Manager
Metropolitan Design/Build

Omar Kassem – General Manager

Hi, I’m Omar Kassem, general manager at Metropolitan Design/Build. I’ve been in the construction industry for 33 years. From the smallest general repairs to building the finest custom homes, we hold licenses in the states of Maryland, Virginia, and the District of Colombia(DC). I currently reside in southern Maryland but enjoy completing home improvement projects inside and around the beltway. We’re members of the Better Business Bureau (BBB), National Association of Remodel Industries (NARI). We’re annual supporters and participants of the Charles County Regional Medical Center Benefit Auction.  Additionally, we’re involved in Christmas in April Toys for Tots and our favorite, Southern Maryland Food Bank.

My experience in the construction industry began when I was very young working for a local home improvement remodeling company. I’m very aware of all facets of the remodeling industry. I am an expert in all forms of interior and exterior renovations. I’ve worked on framing crews and have spent several years as a project manager for a custom home builder before landing at Metropolitan in 1999.

When not putting forth 100% effort into the business, like a lot of you, I run a bus shuttle to my 4 children to and from school and sports events. That takes up all of my extra time.
