About Casey

Casey Oā€™Neal ā€“ Associate Broker, Compass | Arlington, VA Real Estate Expert

With nearly 40 years as a licensed RealtorĀ® in Virginia and over 1,800 homes sold, Iā€™ve built my business on one principle: put the clientā€™s interests first, always. As a longtime resident of Arlington Forest, I know the Northern Virginia market inside and outā€”from historic Arlington neighborhoods to sought-after Falls Church, Alexandria, and Fairfax communities.

As a Senior Transition Specialist, I provide personalized guidance for homeowners and families navigating downsizing, relocation, and estate sales. My team and I support every step of the process, connecting clients with trusted contractors, movers, and estate resources to make life transitions seamless.

Our philosophy is simple: consultative, no-pressure service. Weā€™ll tell a buyer not to purchase a home if it isnā€™t a smart investment, and weā€™ll help sellers unlock hidden equity through pre-sale project management, staging, and remodeling strategies that maximize return.

What sets us apart?

  • Proven Results: 1,826+ successful transactions through 2024.
  • Deep Local Roots: 64 combined years living and working in Northern Virginia.
  • Specialized Support: Senior Transition Specialist services for downsizers and families.
  • Client-First Advocacy: Education, transparency, and guidance that empower you to make confident decisions.
  • Full-Service Support: From pricing strategies to renovation oversight, we manage the details so you can focus on your move.

When Iā€™m not serving clients, my wife Colleen and I share our passion for music, performing across the Washington, D.C. area for more than 40 yearsā€”a reminder that real estate, like music, is about creating harmony and connection.

Whether youā€™re buying your first condo, moving up to a larger home, or preparing for a downsizing transition, weā€™ll provide the clarity and strategy you need for a successful outcome.

šŸ“ž Letā€™s start with a conversationā€”your goals, your timeline, your next chapter.
