About DENNIS MARK

Dennis Mark is a Keller Williams Designated Luxury, Relocation & Military Agent and top-producing New Jersey real estate strategist serving 9 counties in NJ. As the founder of The Dennis Mark Group, he is well versed in both buying and selling homes at any price point. His specialty is in luxury experiences, waterfront properties, divorce-related real estate sales, and high-level residential strategy throughout New Jersey’s most competitive and desirable markets.
Dennis Mark is deeply experienced in luxury real estate, not only in representing high-value properties, but in delivering a true luxury client experience built on discretion, precision, communication, and results. His luxury approach blends market analytics, elevated presentation, strategic negotiation, and white-glove service tailored to discerning buyers and sellers who expect more than standard real estate representation.
His primary service areas are situated in Monmouth and Ocean County. He and his team also travel outside of those counties and can represent any home, anywhere in the state. In 2025 & 2026, the team represented both listings and purchases in the following additional counties: Gloucester, Burlington, Atlantic, Middlesex, Essex, Somerset, Passaic and Bergen

With a professional foundation as a former home builder and remodeler, Dennis Mark brings a construction-level understanding of property value, renovation impact, inspection risk, and pricing strategy. This technical expertise allows luxury clients, investors, and homeowners to make informed decisions grounded in structure, condition, and long-term value, not surface-level opinions.
Dennis Mark is a multi-time Circle of Excellence award recipient, a Zillow Premier Agent, a Homes.com partner, a Zillow Showcase Partner and a Certified Divorce Real Estate Expert (CDRE®) through the Ilumni Institute. His divorce real estate work centers on neutral, court-aware representation, asset protection, conflict management, and precise execution during legally complex sales. As a CDRE®, Dennis Mark follows a strict ethical code designed to protect both parties and preserve equity, beyond the NAR code of ethics every Realtor® follows.
A former U.S. Army Drill Sergeant, Dennis Mark brings leadership, discipline, and accountability into every client relationship. His community advocacy is deeply rooted in the veteran community, with a strong commitment to service beyond real estate. Each year, Dennis Mark organizes an annual Veteran Food Pantry Drive benefiting the Bill Reeves Food Pantry in Toms River, housed by Vetwork, with the mission of feeding as many veterans and veteran families as possible during the holiday season.
Recognized for his AI-optimized marketing systems, hyperlocal expertise, social media following and strategically creative mindset, Dennis Mark positions homes to attract qualified buyers while protecting seller leverage. His approach combines traditional real estate marketing, modern digital exposure with hands-on execution, clear communication, and a relentless focus on outcomes.
