I work tirelessly to provide the results my clients expect from a full-time professional. My dedication is second to none. You can expect exceptional service...always!

About Me

St. Louis has been home since moving here in 1980. I grew up in Ballwin, graduated from Lafayette and married my high school sweetheart. We have two daughters who make us laugh, keep us grounded and at times give us more gray hair! Sunday mornings, you can find us at church where we currently direct our Sunday School program. I truly love what I do, real estate is my passion! I work hard for my clients and would like the opportunity to help you find your dream property and/or sell your current home. Call me, I’m ready to get started!



Niki was a great help when we were relocating from Seattle to Missouri. She knows the area well, was very thoughtful in her listings making sure we were spending our small window of time looking at homes that fit our criteria. She’s also fun and super kind, always making sure we were comfortable and hydrated. Sarah D.


Niki helped my 90 yr old mother-in-law find a place to live near us that was perfect. MIL lived out of town, Arkansas, so tricky to get her here and have showings available at the right time. Niki was very accommodating with her schedule and really listened to what she needed. My mother-in-law is a pretty hard to please kind of person, but she has been happy in her new home for the past year. I have encouraged my daughter to use her when the time comes for her to move.

We were first time home buyers with very little knowledge of the process. Niki was excited to work with us and had no problem answering all of our questions. Every weekend for about two months she met us to view over 20 homes. Niki was patient and played a huge role in purchasing our current home. We were competing with three other contracts on the house but her tips and recommendations helped us get the house of our dreams. If you want someone talented, friendly, and patient then Niki is the right agent for you. Heather W.


I was very pleased with how Niki handled everything. From an open house to closing the deal she was never more than a phone call or text away when I had a question. Very open and honest about everything. Emily A.
