His decades of experience include ground-up construction and all phases of renovation. With his extensive project management experience, Mark delivers technical and cost-effective completion on all client projects. His knowledge of established building codes, laws, rules, regulations, and policies have saved his clients millions of dollars.

He develops and maintains a professional working relationship with construction contractors, subcontractors, engineers, and architects. Or, as he puts it, “I am lucky enough to have never worked a day in my life because I have a passion for what I do.“

Mark works tirelessly with various philanthropic endeavors throughout the Tri-state area.  From organizing charity golf outings to honor our Military heroes, and helping soup kitchens feed the hungry, Mark has made it his life’s passion to help others.
