Ask Mark & Diana - The Massey Team


Mark and Diana were very helpful from the beginning to the end of the process.

- David P

We have really enjoyed working with Mark. He helped us buy our first home 12 years ago, and then when we were ready to move, most recently helped us both sell that house and buy our new one. Considering how many clients he has had in the time since when he was first our realtor, we were so impressed that he still remembered us and our first home! He really knows us as people and has a great sense of our preferences. When looking for our new home(s) we would joke that he was our “reality check” for what work we could handle doing on a house, and what houses were truly worth what they were asking- his perspective was invaluable. He was very responsive throughout all the complicated transactions he helped us through in the past few months and I can’t imagine trying to do all that on our own. We would definitely recommend working with him.

- Erika L

We would not have trusted the sale of our home of 30 years to anyone else! Both Mark and Diana are the epitome of professionalism and attention to detail! From pre-listing meetings and advice through the closing, they both made sure all aspects of the sale were in order and that we knew how everything was progressing. The Massey Team is the BEST!

Mark and Diana Massey made our house buying experience as smooth and easy as it could possibly be. We were buying in a difficult market and it took a while to find what we wanted, but they were very patient with us and helped us find a house we really love. We highly recommend them.

- Beth C

Mark is very easy to work with. He is very knowledgeable & quick to answer questions. And he is quick to resolve any issues that might come up.

- Jose C

From the day we signed a contract for The Massey Team to list our home and throughout 6 offers, accepting a contract, and until the day we closed, Mark was communicating all the way. We were very pleased with his experience, professionalism, communication and friendliness during our time selling our house. We definitely recommend The Massey Team.

- Teresa M

Mark was very helpful and extremely good at promoting the house, sold immediately after we put it on the market. He stuck with us and was helpful during the house preparation, even going out of his way to run over and unlock the door for a contractor when we weren’t able. Thank you Mark.

- Todd M

Mark is a wonderful person and fantastic real estate agent. He went over and above every single time we had questions or concerns. Every property that we asked to see, we saw. Always we felt comfortable and well taken care of. I would recommend Mark over and over again.

- Katherine S

Mark and Diana immediately got on the same page as us providing us with options ideal for our family. In this market it’s easy to get discouraged by They stayed vigilant in showing us home after home that we loved. We finally sealed the deal with ours and couldn’t be happier. Thanks you two!

- Keenan K

I worked with Mark for my company relocation. He was very helpful in the process for preparing to visit and was in tune with what I was looking for. I enjoyed my experience looking at potential homes and found a wonderful home that I now happily reside in. Thank you, Mark! I highly recommend him to anyone looking for a home!

- Jennifer H

I am very pleased with the service I received. from Mark Massey. The whole process was seamless. From the day I first called to request his service to help us sell our house he has been ready and eager to answer all my questions and gave us advice that made it easier to sell the house. He also helped us select the staging company and Andrea was exceptional. We had to be out of town and he was able to handle everything remotely and seamlessly. He arranged the showings and he got an offer after the first day of showing I cannot say enough good things about his professionalism, his pleasant disposition and efficiency. I will not hesitate to highly recommend him and his company to all my friends and colleagues in the Edwardsville/Glen Carbon area. Thank you Mark for all your hard work.

- Imelda B

Mark was very pleasant to work with. He went the extra mile to get the house closed in a record 24 days, despite several setbacks with the title company and lender, at no fault of him. We will also say that this was also a relocation deal for both the seller and us, so there was a lot more involvement and legwork from Mark. He is extremely knowledgeable of the Madison County area and showed us around on our home finding trip. We were purchasing from out of state, but he made everything a breeze. He also assisted with utilities setup through Berkshire Hathaway's program. We would definitely recommend Mark to our friends and family and would use him for future real estate transactions. Unfortunately, we didn't get to work with Diana on this property directly, but she was very friendly and made us feel at ease with our out-of-state move.

- Andrew F

Mark was the only person in the home buying process that explained the next steps. My dude and I would be so lost without him!

- Ashleah S

We worked with Mark for our relocation. During our home finding trip, Mark had generated nice booklets with the houses we would be viewing. He was very organized and chauffeured us around. There were a lot more houses to see than we originally thought. Mark was very accommodating even when we asked to see a home for the third time. After our offer was accepted, Mark was there 24/7 to answer any and all questions we had until close.

- Bethany F

Mark knows what he's doing, and does an excellent job. He was friendly, professional, and attentive throughout the entire home buying process. He communicated frequently to let us know what the next step was, and was able to answer any questions that we had along the way. I don't think this job could be done any better, or the process made any easier. Thanks Mark!

- Dillon S

Very professional, diligent and courteous.

- Linda M

My husband has used Diana Massey as his realtor for his previous home purchases in the area and I can see why. She and her son are joy to work with and they were on top of everything regarding our home purchase. I would highly recommend them to anyone looking for the best realtor.

- Melanie H

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.

- Walter T

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.

- Shivani S

Mark was great. Made it a simple process.

- JoAnn M

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!!

- Diana T

Very knowledgeable and professional. Made the process of buying a home easy. Really felt like they had our best interest at heart.

- William F

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
