Get to Know the Faces Behind Our Success

Sprengel Real Estate Group

We understand that a house is not just a property to you, it's home. A place you celebrate special days, and entertain. It's where your babies took their first steps, and where you raised your family. We understand that while this is a business transaction, it’s almost never “just business.”

We believe in personal service, building relationships with our clients, and keeping in touch long after the closing is done.

I’m a wife of over 25 years to Robert, and a mom to three children and three dogs. Our oldest daughter is married and lives in Nashville, TN. Our son is working, and living at home, and our youngest is in middle school. I have two bachelor's degrees, from Concordia University Wisconsin, in Education and History - with a minor in psychology, and used those in the classroom throughout my early adulthood. Now, I love being a full time Real Estate Broker. I love the hunt of finding buyers their next home, piece of land, or investment property. Photography interior design, and singing are some of my creative passions. I love to travel, advocate for adoption and orphan care, volunteer in our local school district, and support the amazing Make-A-Wish organization. You may also find me attending concerts and seeing musical theater on a live stage.

Living in southwestern WI my whole life gives me valuable knowledge about the area. I am a top producer in my brokerage, and the top 1% of agents in southeast Wisconsin. I intentionally structure my business in such a way that I am never too busy to provide excellent service to the clients who trust me to sell their home and help them find their next home. A home is typically your largest asset and investment. It is definitely something worth hiring a professional to handle with care, professionalism, and great attention to detail.

My goal, if you are selling your home, is to get you top dollar and the shortest time on market. My goal, when helping you purchase a home, is to do what is necessary to compete and *win* your dream home. Whether buying or selling, moving is an exciting, scary, stressful, yet beautiful experience. I will be an advocate for you, and walk with you, as you take your next step in selling your current house or purchasing a new home or investment property. It would be an honor to serve you.

I've been a wife to Jason since 2014. I'm a mom to two children. Sam since 2016 and Jamie since 2018. They attend Brookfield Christian School. I grew up in southeastern Wisconsin in Wauwatosa, Oconomowoc, and Hales Corners. I have two bachelors degrees from Wisconsin Lutheran College. One in Technical Theater and one in Communications. I used those throughout my early adulthood. Presently, I enjoy being a Realtor with Sprengel Real Estate Group. I am a book lover. I am always reading something. I enjoy cooking, music, theater, gardening, serving at my church, and volunteering at our children's school. Organizing my home and the homes of others brings me joy.

You'll often find me drinking coffee in the morning, and lots of it! Matching people with their next home is an honor and privilege that I don't take lightly. I have loved helping first time buyers purchase their first home, as well as guiding our investor clients towards a property that will offer them passive income and achieve their financial goals. One of the things I love most about our team is how our shared experience becomes an asset to our clients, how we support one another, and how we live generously in our community. I love to bless and support our local schools and teachers, as well as drama and the arts. Giving back to the community is important to me.

I am a husband, father, consultant, and friend. I strive to use my 20+ years of being a high-performing, 'Corporate America' sales leader and professional and leverage that to bring about the best client/customer experience in the residential real estate market. I understand that this profession is all about people and not really the properties. I seek to understand and aim to deliver above expectations in all that I do.
