Keri O'Sullivan Welcome!

Personalized service begins with understanding each client's goals. But achieving those goals also requires market knowledge, financial insight, professional experience, and the ability to negotiate effectively.

My clients benefit from the knowledge I gained earning degrees in Finance and Economics, my previous experience as a Financial Analyst, and my years as a REALTOR® and Associate Broker with more than $150 million in sales. This combination of financial and real estate experience allows me to help buyers make informed decisions and sellers accurately assess market conditions, position their properties effectively, and maximize their home sale price.

I specialize in Washington, DC and Northern Virginia, including Arlington County, Falls Church, Alexandria, Fairfax County—including McLean, Vienna, Reston, Herndon, Springfield and Burke—and Loudoun County, including Sterling, Ashburn and Leesburg.

I pride myself on providing a memorable real estate experience to each of my clients. Repeat clients have described me as "genuine", "knowledgeable and experienced", "reliable", "professional", and a "shrewd negotiator." Buying or selling a home is a substantial financial decision, and choosing the right REALTOR® to represent your interests matters.

Every relationship begins with a thorough analysis of my client's individual situation, priorities, and goals. That understanding, coupled with my genuine desire to help, allows me to provide thoughtful guidance and deliver exceptional results. I work diligently to give every client the respect, attention, and personal service they deserve. I want every client to feel like they are my only client!

Over the years, I have earned a reputation for being an experienced real estate professional and conscientious advisor to my clients. Call or email me, and discover what differentiates the real estate experience with me. I look forward to the opportunity of working with you!
