My Story
I have over 20 years of Real Estate ownership experience and understand the needs of homeowners, residential & commercial investors, and tenants. I pride myself in providing the best possible experience in any real estate need that you may have, including a new custom home in collaboration with Winfield Homes.
I also have 15 years of experience as an electrician, as well as 5 years of experience as the electrical/building inspector for the City of Fond du Lac and some surrounding municipalities. I am very well connected and this experience provides me with the ability to provide you with the full spectrum of Real Estate Services that many others can't offer.
Whether you're a first-time buyer or seller, a seasoned investor, or developer, I know what you need and expect from an agent and place your needs as the top priority. I can help you with your tenant needs if you're just getting into rental properties and I am able to market your property to the right investors if you're looking to sell. I really enjoy working with first-time homebuyers and seeing that same excitement and joy that I felt that comes with buying your first home. I can help you find what you need and want in a home that will fulfill your needs for many years to come. It really is a great experience!
Whether you're buying or selling, I will work diligently to get you results as soon as possible. I am a very ambitious person and find great importance in being completely honest and being true to my word. I don't know all the answers, but I know where to find them and won't stop until I do! When you hire me to be your REALTOR®, I will be available to you at all times. We will work together to get the results you need and expect.
I look forward to working with you!
