About
With 24 years of real estate experience, I have built my career around one simple goal: helping my clients feel confident, informed, and genuinely cared for throughout every step of their real estate journey.

I began my career in 2002 and have had the privilege of working with several highly respected real estate companies. During my time with RE/MAX Specialists, I served as a Buyer Specialist with a highly successful team and was repeatedly recognized for my production and sales accomplishments. I continued earning top-producer recognition with ERA Davis & Linn, including ERA Leaders’ Circle and Circle of Achievement honors. Since joining Coldwell Banker Vanguard Realty in 2024, I have continued to receive recognition for my sales, listings, and overall production.

Today, I proudly serve buyers, sellers, military families, veterans, first-time homebuyers, retirees, and clients relocating to or from Northeast Florida. I have extensive knowledge of Jacksonville, St. Johns County, St. Augustine, Mandarin, Fleming Island, Orange Park, Green Cove Springs, and the surrounding communities.

Whether you are purchasing your first home, moving into a larger home, downsizing, relocating, investing, or preparing to sell a longtime family property, I understand that every situation is personal and unique. I take the time to listen carefully, explain the process clearly, and develop a strategy based on your specific needs and goals.

My clients benefit from strong negotiation skills, extensive market knowledge, honest guidance, personalized attention, and dependable communication. I am responsive and accessible because I believe you should never feel uncertain or uninformed during such an important transaction. From our first conversation through closing—and long after the sale—I will be there to provide guidance, answer questions, solve problems, and protect your best interests.

When representing sellers, I provide thoughtful pricing guidance, professional marketing, careful preparation, and a customized plan designed to attract qualified buyers and achieve the strongest possible outcome. When working with buyers, I help identify the right opportunities, evaluate properties, prepare competitive offers, and confidently navigate inspections, financing, and closing.

Qualified clients may also be eligible for my cash-back incentive program. Eligibility and incentive amounts may vary depending on the transaction and program requirements, so I invite you to contact me for complete details.

My success has been built on integrity, experience, hard work, repeat clients, and referrals from people who trust me. I would be honored to put my 24 years of experience to work for you and help make your next move as smooth, successful, and rewarding as possible.
