The service and dedication to making this as pain free as possible was wonderful. We were kept informed every step of the way and they handled almost every aspect of sale. I am very appreciative for the excellent service and the prompt and thorough responses to questions or concerns.

I actually worked with Diana’s son- Mark Massey. He is simply amazing and I could not have asked for a better realtor. He was never pushy, understood my needs, was very efficient, approachable and negotiated for all that I requested. I was a first time home buyer and appreciated his patience with all my questions. Overall Mark is very dependable and I will surely use him again for all of my future real estate needs.

Mark was great. Made it a simple process.

We are so fortunate to have found Mark Massey when we moved to St Louis! Mark was easily the best realtor we have ever worked with. We never felt rushed during showings, and Mark was always willing to work with our schedule. He traveled near and far to help us with our home search. And with the competitive market and the housing shortage, it took us nearly a year to find our dream home, and Mark was very patient with us throughout that journey. There is no doubt that Mark had our best interests at heart, and without his guidance we would have never been able to score our dream home! We consider him a true friend! Thank you for everything, Mark!!

- William D French

Mark was amazing to work with, made the home buying experience joyful, in a time where houses are selling faster then you could even look at them, he kept us in the know for what’s new and available, showed us what’s available and we ended up with the perfect home and location for our family. Thank you so much for all your hard work
