About
I have been a real estate agent since 2017 and have ranked in the top 20-40 percent of local agents in yearly transactions and volumes since 2018. I have a proven track record of saving my clients significant amounts of money with my negotiation skills alone, many times saving them more than they compensated me for my services.
Aside from my track record of being able to pay for myself, I focus on my client's well-being in the financial, physical, practical, emotional, and spiritual aspects of the transaction. I strive in learning what is most important to my clients and facilitate in achieving the best results possible, and always put THEIR interests first, regardless of how much I may financially gain, if I even financially gain anything at all.

Does this make me the biggest earning, top real estate professional? No. Does it make me be able to look at myself in the mirror and know I did the right thing? Absolutely.

If you’re buying a house in the St. Louis area, run, don’t walk, to Jen.
I knew Jen was great—my sister used her as her realtor and raved about her—but after working with her myself, I can confidently say she’s in a league of her own.
She called me five minutes after I submitted my inquiry email. On a Sunday. At her birthday party. That kind of responsiveness never wavered—Jen picked up the phone no matter what, made me feel like I was her only client (in the best way), and never once made me feel like I was asking too many questions. In fact, she welcomed them and always made sure I felt heard and informed.
Jen gave me her honest advice while always respecting my preferences. I never felt pushed or sold to. Her recommendations—from inspectors to lenders—were all spot on. Every person she referred was just as thorough and trustworthy as she is.
At one point, we were struggling to get info from the HOA. Jen wouldn’t take no for an answer—she hunted down a title company that could get the answers we needed. That’s the kind of tenacity and care she brings. It honestly felt like I was working with family.
Jen is sharp, thorough, patient, and incredibly kind. I couldn’t imagine going through this process without her, and I recommend her to absolutely anyone buying a home in the STL area.

Jen helped me find a diamond in the rough fixer upper while helping me stay on a strict budget. Even though we were looking at low cost homes she still gave high cost service! Great/fierce negotiator got me everything we needed/wanted from the seller. Made the whole process streamlined and as stress free as possible (even though buying a home can be an emotional experience). Will definitely use her again in future and recommend her to every one I know.

Jen is a Gem.

We were moving from California, and needed to find a house to buy. She worked with us to find houses within our budget, and move-in ready. She made it quite easy to do transactions long-distance. She explained processes and procedures in order to proceed, and guided us every step of the way. Her knowledge of the area, and her negotiating skills were fantastic. Since we were able to pay cash, the process was quicker than usual, but the time from first contacting her to final close, was 30 days. That was quite the accomplishment.

Jen was amazing! She showed us so many houses with the specific things we wanted, and worked with our schedule to find time to show them to us. She was always positive even after the rejected offers and kept us motivated when trying to find a house in this market.
