Whether you are buying, refinancing or embarking on a construction project, it is important to have an experienced mortgage professional to help you analyze your financing options and ensure a smooth and stress-free process.

As a tenured employee with nearly three decades of experience all at Wintrust Mortgage, I have the expertise to get you the right mortgage and handle your transaction professionally. With my vast experience, especially with self-employed borrowers and Wintrust Mortgages' rates and various programs, you are sure to get the product that's right for you.

If you are considering buying a home, please remember to get me involved early on in your home buying process. Early involvement not only gives you a better idea of what you can qualify for, it also gives you a stronger negotiation position with our Premier Buyer Pre-Approval letter when you find the home of your dreams.

I am a lifelong Chicagoan, a diehard Cubs fan and an alumnus of the University of Dayton and Loyola Academy in Wilmette. I've lived and raised my family in the same community for 22 years. I truly enjoy what I do and am thankful for the support, longevity and successful career Wintrust Mortgage and my team have provided me.
