My Real Estate Journey
New Construction Roots (2003)
I began my real estate career in 2003 working in the new construction industry for a local builder. This foundation gave me deep knowledge of the home building process that I still leverage today.
Finding Real Estate
In 2012, I transitioned to residential real estate and have since helped hundreds of families buy and sell homes. My passion is guiding clients through the complexities of real estate while making the experience enjoyable.
Joined Gateway Realty Group (2020)
In 2020, I joined Gateway Realty Group — a move that aligned my values with a team that truly puts clients first. Being part of a boutique, relationship-driven brokerage has allowed me to give every client the personalized attention they deserve.
CNBC Feature (2024)
In 2024, I represented Gateway Realty Group on a nationally televised CNBC interview discussing the hottest real estate markets, and St. Louis made the list! It was an honor to share why our city is such a great place to live.
What My Clients Say
Don’t just take my word for it. Here’s what families I’ve worked with have to say.
"Kellie isn't just a great realtor, she's someone I'll keep in my life for years to come. I wholeheartedly recommend her to anyone buying or selling a home. She's amazing!"
Natalie Kniepman
"There is no doubt Kellie Lasater is the best realtor out there in a world of lazy part time realtors who seem to just do this to have something to do. Honesty and integrity are hard to find in this profession and she would walk across fire for her clients. To say I would highly recommend her would be an understatement!"
Kristy Cousineau
"Her many years of experience is shown through her in-depth knowledge of new construction and the rapport she has with builders... She helped us find errors that needed correction on the walk throughs and followed up on their resolution."

St. Louis Raised
I was born in Detroit, Michigan and moved to St. Louis when I was five years old. This city has been home ever since. From growing up in North County to currently residing in Wentzville, I have deep connections in the community and intimate knowledge of the local housing market. I attended Rosary High School (Class of ’85) and went on to study at the University of Missouri-St. Louis (UMSL).
The experience I’ve gained from living and working all over the St. Louis area makes me an invaluable resource when deciding where to live and how to navigate this dynamic market.
Why Work With Me
The difference is in the details and the dedication.
Client First
Your needs come first. Always. I'm available almost any time of day and I won't stop until you're taken care of.
Experience Matters
I bring 21+ years of expertise to every transaction. I've seen a lot, and I use everything I've learned to protect you and guide you forward.
Local Expert
I was born and raised in St. Louis and I've lived all over the region. I know these neighborhoods, these builders, and this market inside and out.
Stress-Free
Buying or selling a home is a big deal. I take that seriously and work hard to make the whole process as smooth and enjoyable for you as I possibly can.
Beyond Real Estate
Family & Life
When I'm not selling real estate, I enjoy spending time with my husband (owner of Lasater Automotive in O'Fallon), my 4 sons, my 2 Boston terriers, and yes, my pet snake! I especially love cheering on my youngest son at baseball games. Family is the reason I work as hard as I do.
My Cancer Journey
In 2012, I was diagnosed with cancer. It was the hardest thing I've ever faced: surgery, recovery, and all the uncertainty that comes with a diagnosis like that. There were days that were genuinely difficult, but I leaned on my faith, my family, my friends, and the same stubbornness that makes me good at my job.
I made it through, and that experience reshaped how I show up for people. I don't sweat the small stuff anymore. I know what actually matters. When a deal gets hard or a client is stressed, I draw on everything I went through, and I stay steady. My clients deserve someone who knows how to calmly navigate through difficult situations.
Interests & Hobbies
I'm a homebody at heart and love watching true crime shows. I love social media (especially making TikTok videos!) and enjoying the wide variety of restaurants St. Louis has to offer. In the summer, when I'm not selling homes or watching my son Kasey play baseball, you can find me outside at the pool with my dogs. I also love watching the Savannah Bananas play. Their style of baseball is pure joy to watch. And yes, I still make time for a good TJ Maxx run.
I Love Animals
When I was little, I wanted to be a veterinarian. Fast forward a few decades, I ended up in real estate instead. I live on 5 acres in Wentzville and I wouldn’t have it any other way. Between the cats, the chickens, the dogs, and yes, the snake, I basically run a mini farm. Taking care of them is my form of therapy.
