"Dennis is incredibly knowledgeable and responsive. He made everything easy to understand, and helped us feel great about the overall process. I definitely recommend his services!"



If you are looking to buy or sell a house, I would strongly encourage you to call Dennis Gullion. Dennis sold our house within a week! He is very knowledgable and knew exactly what we needed to do to get our house ready to sell. Dennis is a very sweet and receptive person who cares about people. He listens and tries to meet individual needs. He was always available to answer questions. Dennis made our experience of selling our home a positive, easy experience. We feel like we have ended up with a life-long friend!


As a first-time homebuyer, Dennis was wonderful to work with! Not only did he listen to me about what I needed and wanted in a home, he also educated me o what to look for in regard to both value adding amenities and potential pitfalls. Dennis also walked me through the home buying process and kept me informed of everything as it was happening. He answered all my calls/texts/emails in a timely fashion. He is professional and courteous, but also fun to work with. I would recommend him to anyone without hesitation and will use him again in the future.

I’ve been working with Dennis on the mortgage end of the business for about 2 years. It was during this time that I realized how involved he was with his customers. When my friends had their home listed and were complaining about the service they received. I told them to contact Dennis Gullion of Gullion Properties. At that time, I was working with Dennis on a loan that was only about $50k. The time and effort he put into this purchase of this home was when I realized that he truly cares about his customers getting into a new home. He was focused on the relationship he was building with his customer and not the money. I told my friends about this loan he and I were working on, and they decided to call him. He sold my friends’ home in about 3 weeks and then proceeded to find them their dream home. When I decided to downsize, I called Dennis. I didn’t want to give my home away and he completely understood. I wasn’t sure if we would even sell our home because of the economy. He was patient and knew we wouldn’t reduce the price of our home and brought us a buyer with an offer within $4k of asking. We couldn’t have been happier. I was worried when we sold our house, that I wouldn’t find something that I liked. I didn’t want to move to a neighborhood that looked like the one we just left. He kept telling me “Don’t worry, something always comes up.” As luck would have it, something did come up and Dennis got us into our dream home. I have recommended Dennis to several people, even strangers. My friends have a saying.... “If you want to sell your home, call Dennis. He’ll leave you homeless! He’s honest and possibly the hardest working man in real estate!” Thank you Dennis, we are truly blessed to have a friend like you in our lives!

Dennis came highly recommended to us and did not disappoint. He knew that I had a deadline that I needed to find and purchase a home and he helped me and my fiancé to find the perfect home and complete all the paperwork so we could sign and get moved in before our wedding. Dennis is truly a man of God. All of his efforts were a blessing to us.

This is Alex and Ana Nunes, and we are (finally!) writing to thank you for ALL you did for us! To refresh your memory, we put our home (2910 S Country Club in Garland) on sale back in mid Nov 2010 and by Jan 5, 2011 it had been sold! We were obviously worried when the house was put on the market during the holiday months leading to the new year. Well, it was so silly for us to worry. You never tired in helping us, answered our many phone calls, kept Alex up to date on everything that was going on, set up plenty of site visits, and worked tirelessly to get the home a new owner. You assured us someone was going to love that house as much as we did, and you were right.

You made what is normally is very stressful process a breeze and the time just flew by. You were a pleasure to work with and such a delight. You kept confident and assured us that everything would turn out ok in the end and for that we thank you so much.

We wanted to send this to your office, and everyone who works with you, as we wanted them all to know that you are awesome and just the best and we treasure the time we were able to work together. Please forward to anyone who you may think necessary, and feel free to post anywhere you see fit. We’d love for everyone around the Garland/Rowlett/Rockwall area (and any other you might be familiar with) to know that they need to come to you when they are looking to buy a home or put it on the market. Again, thank you so very much for all you have done for us. We will definitely be looking for your help when we are looking to buy or sell again, and rest assured, we will be doing some PR for you to all our friends and family. God bless you for what you did! With warm regards and a thankful heart.

Dennis Gullion was the property manager for the home we were renting and when we decided to begin to search for a home to purchase there was never a question of using anyone else as our realtor. He not only educated us on the complicated process of purchasing a home, but he advised us on the best way to do it. He helped us to figure out what we wanted in a home, and then he found us the perfect house. He is not only a wonderful real estate agent, but he is a wonderful man. He truly cares for his clients like they are his family and he does a fantastic job to take care of them. We highly recommend Dennis Gullion to everyone who is looking for a home and we will definitely use Gullion Properties again in the future.

From our first contact with Dennis, we felt assured we had made the right choice in selecting him as our realtor. He is a kind, honest, Godly man who puts his clients first. Dennis made our first home buying experience a quick and easy one. He listened to exactly what we looked for in a home, and led us through the purchasing process - teaching us along the way. It is very refreshing to find a realtor /businessman like Dennis, and we would highly recommend him to anyone looking for a realtor!

Joy and Alan

When we made the decision to sell our home the best part of that decision was when we decided to list our home with Dennis Gullion. Thank you Dennis for your knowledge, expertise and especially your kindness. You are one in a million and our advice to everyone will be to call you if they are thinking of selling or buying!

Dennis Gullion was a pleasure to work with. We told him what our wants, needs, and hopes were when looking for our first home. We thought the search for our home would be so difficult and that we would probably have to look at a dozen or more homes before we found the one. Little did we know that on the first day of looking at homes with Dennis that we would find the house that was perfect for us! I couldn’t believe it. He delivered and even went above and beyond. We love our new home and are excited for the wonderful memories that we will be making here. Thank you Gullion Properties!
