What My Clients Say ...

If ever there was a situation that called for "an expert", contemplating the sale of my home was an undertaking that demanded professional attention.  I already knew that Penny Schneithorst was an experienced and talented agent, but I quickly learned what set her apart was her attention to detail and her penchant for timely, clear communication throughout the process.  Penny delivered on every promise and exceeded my expectations.  I'm pleased to offer this recommendation to anyone seeking a high quality agent that knows the market, communicates clearly and delivers outstanding results!  11/3/2023

Trying to find the perfect home can be difficult and sometimes discouraging.  Penny worked with us for a year and continually gave us multiple options throughout that time.  She was tireless and always optimistic, even when we weren't.  Finally, Penny's greatest attribute solved our problem:  her contacts and acquaintances as a lifelong St. Louisan; everyone know Penny.  She found us the perfect property in a much sought after location, and all before the property hit the market.  Thanks Penny!  You're the best!!  5/2/23


Seller of 25 Trent Drive and purchaser of another home writes…     

My wife and I couldn't be happier with our decision to hire Penny and Mary.  The sale of our Trent Drive home was fast and easy thanks to their large database of contacts and marketing strategy.  While we certainly appreciated this, we are most appreciative for their patience, responsiveness and guidance during the search for our next home in a very competitive market.  After a roller coaster of missing out on several homes, we finally found the right one.  Penny and Mary were just as responsive and patient as they were at the beginning of our search.  4/19/22

Mary and Penny provided top-notch service and insight from the initial contract offer, negotiation and acceptance of the offer, through inspections and closing.  Their guidance and market intelligence in this current competitive and fast-moving home market made purchasing my forever home a reality.  Their service was seamless and the communication couldn't have been better.   4/20/22

We are so grateful to have had Penny and Mary help us find our amazing home.  They made the process simple from starting to look to closing.  Both are great with communication, answered when called or texted and always had knowledgeable answers.  When negotiating, what was in our best interest was their top priority.  We would recommend them to anyone.  4/20/22

Mary and Penny could not have been more professional in the selling of one home and purchase of another. Their expertise far exceeded any realtor I’ve ever dealt with. I truly feel blessed to have the good fortune to have had them represent us. The print material and video in the listing were superb. Everything was handled to perfection from getting the house ready, to showings, to the closings. Thank you for all your dedication and hard work!  4/25/22


Satisfied Seller writes…

Mary and Penny provided exceptional service to our family that was above and beyond our already high expectations.  This was our family home for the past forty years and now was owned by the adult siblings.  Mary & Penny were sensitive to the emotional attachment that all of us had for our home.  Their extensive knowledge of the market was apparent.  Their guidance and hard work helped our family achieve the goal that we had asked of them. Mary & Penny have our family’s deepest gratitude for their exceptional efforts.  4/21/22

I had a very positive experience with Mary and Penny as my buyer's agents. They were professional and helpful throughout the entire process of showing, closing, and everything along the way.

I highly recommend them.  4/20/22

I had very specific notions about where I wanted to move following my service to the City of Town & County, but few definitive ideas about how to make it happen.  Penny and Mary solved that challenge for me!  Not only did they find the perfect home in my ideal location, but they helped me present a winning offer in a very competitive and complex market.  As if that wasn’t enough, they marketed and sold my existing home to a strategic buyer, allowing me to maximize the return on my investment.  Penny and Mary are very professional, smart and hardworking, and I could not be more grateful for their advice and representation.  4/20/22
