A seasoned real estate veteran, I have been successfully helping my clients buy and sell their properties since 1981. MY desire to make the real estate transaction run as smoothly and effortlessly as possible is what drives me to do the utmost best for my clients every day. I know that the buying and selling process can be much like riding a roller coaster – there are many ups and downs, sometimes even dark tunnels – but I am here to make sure that you stay on the rails. My greatest talent is having my clients feel safe and secure knowing that both their needs and their wishes are being met.

With over 30 years of negotiation skills, the final stages of firming up a contract are second nature to me. While remaining optimistic and positive in all stages of the real estate transaction, I will be sure to remain persistent and fight for clients to ensure that they get more than what they want.
