About
16 Years experience. Award winning top producer. I have called Berks County my home all my life and I enjoy the diverse landscape that it has to offer. I have had the pleasure of residing in various locations around Berks, which gives me a firsthand perspective on what makes each area unique. My experience professionally has been in management, which to succeed, comes down to actively listening and being able to deliver results. I am a full-service agent with experience in land, commercial, new construction, multi-family, condominium, and residential sales. I enjoy the process of meeting with new clients and developing a plan that will get you the results you deserve. Feel free to contact me if you have any real estate related questions, if you are looking for guidance on the next step, or you are ready to buy or sell.
