Alex’s heart belongs to St. Louis. As a life-long resident, Alex is always out & about soaking up all the amazing things (and food) this town has to offer. As a SLU graduate she jumped right into a professional life as a Financial Analyst & the detail-oriented, punctual part of her loved that job but her kind, helpful nature wanted something more. Alex loves working with first-time home buyers to find new homes. Some of her favorite places are South City, South County, Brentwood & Webster.

Things you must know about Alex: She drives a stick shift & feels like she’s being lazy when she drives an automatic, she actually knows Fredbird (in real life!) & doesn’t know how to ride a bicycle. Alex & her husband love trying new restaurants & recipes & traveling.
