Over 25 years of experience assisting clients, friends and family in the sale and purchase of their home.

I love this business and can't imagine doing anything else! I bring best knowledge of this industry to my clients and have assisted hundreds of home buyers and sellers by understanding the local market and negotiating successfully to attain their dreams. People have different opinions on how a real estate salesperson should represent their client, but honesty and integrity should go without saying. I am a firm believer in exceeding expectations and enhancing your quality of life. To me, being a REALTOR means more than selling homes. It's about you, your hopes and your dreams. It's about a relationship based on trust, knowledge and expertise. You can be sure I will go the extra mile to give you the best possible experience when buying or selling real estate. I love my job and my performance reflects that. 

Please feel free to use this website as a resource for all of your real estate needs, and if you have any additional questions, don't hesitate to contact me today!

Community Involvement

I am very involved in my community, specifically in my office.  I enjoy helping new agents learn the business and believe that being part of a team is a key factor in success.
