Senior Mortgage Consultant
Wintrust Mortgage

With more than 20 years of lending experience in southern Wisconsin, I can help you navigate through the mortgage process, whether you are buying, building, or refinancing. I break down the process into four simple steps and will personally walk you through each individual step. When you work with me, you can expect fast and accurate communication, and I am available via phone, text, and email—whichever works best for you. I provide consistent updates and personalized service to ensure a great experience.

Wintrust Mortgage has many financing programs, including FHA, VA, WHEDA, and medical professionals loans. Our experienced underwriting and closing teams are also in-house, which means you can expect fast and reliable mortgage approvals, along with a seamless closing.

Breanna Jones

At the very beginning of my professional career, I was introduced to mortgage lending and fell in love with it. Now, almost a decade later, I continue to serve clients who are looking to refinance or purchase homes with that same enthusiasm.

I truly look forward to helping you navigate the mortgage process, and I’ve learned that clear and responsive communication is the key to a successful transaction. Let me be your advocate in securing the financing that’s right for you and your family.

"Breanna Jones walked me through every step of the process and was proactive in all her communication. Before I knew I wanted to go with Wintrust, she helped me understand what I was in for as I started to look for a home and wanted to get my loan preapproval. I have already recommended her to friends who are looking to start the process."
