"Dennis has been our Realtor of choice for 20+ years!

He has not only helped us with residential properties, but commercial properties as well. The knowledge, expertise, and care he gives to his clients is unmatched. He's not just our Realtor, he has also become a great friend!"


"I was very blessed to have been able to have Dennis working with me!

He did everything in an expedient manner. Dennis ensured things got done even when I was not able to do much because I was working. He is well organized, knowledgeable, and thorough. My family will continue to use him as our Realtor!"


"Dennis is the best!

I needed this house sold for an estate situation and Dennis got it done quickly. He was in constant contact with me all the way - keeping me inform. His enthusiasm kept me going . He was so positive - it kept me positive. He also is a great negotiator and had my best interest in mind at all times - He said he would sell by the end of the year and he did and got very close to the original asking price. I know this is more than a job for Dennis - it is his passion to help people. Thank you again Dennis from the bottom of my heart"


"Dennis was absolutely incredible!

As a first time home buyer, I had so many questions and Dennis answered every one of them. He was genuinely interested in our success with home buying and never rushed us along. In the few back-and-forth exchanges we had with the seller, Dennis was our number 1 advocate every time and got us a cheaper sales price AND seller-paid repairs. If you want a realtor who is interested in you and will work to find what is best for you, contact Dennis Gullion. His character, personality, and willingness to work hard make him stand out, and as my wife numerous times noted, you never feel like you're just ‘one of many clients’ with Dennis. You feel like you're his only and most important client. I cannot recommend enough."

"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!"


"Gullion properties was amazing,professional, and friendly.

They made the home buying experience easy, stress free and enjoyable!! We hope that everyone that chooses them shares the same experience and treatment!"


"I can't say enough about Dennis's professionalism, true caring nature, and extensive knowledge/connections.

He brings all these qualities to the table for his clients, not just in the real estate transaction, but in the transition to their new home/community. We purchased a home from Dennis in 2015.  We picked Dennis as our realtor because we knew him from church , but it has gone way beyond That now. He don't just sell you a house , he is there for what ever you need. Dennis then helped us sell our house in 2017 when we needed to get rid of it quickly. Throughout the process, Dennis was extremely caring, responsive and just there for us.

Dennis doesn't forget you once the deal is done. I have called Dennis for recommendations of all different kinds of issues, and needs.. He has always come through with excellent, timely recommendations. All the people I have interacted with have such glowing things to say about him as well. To this day, he always makes me feel like helping me is his highest priority. I highly recommend his team for your real estate transaction."


"Dennis not only made the process of selling our home easier, he made it fun!

The combination of commitment to his clients, years of experience, and wonderful personality make Dennis a joy to work with. He graciously provides his expert opinion while never attempting to force or coerce. Someone with such a high level of skill and honesty in this industry is a wonderful find!"


"Dennis was our realtor for our recent purchase in Rowlett, TX.

Dennis showed us numerous houses and was honest in his assessment of each house. We had several where he would simply say 'this is not your house.' He knew what we wanted and where we wanted to be even before we really knew what we wanted just off our description of our ideal home. His knowledge of our region was impressive with detailed experience of each neighborhood we discussed. Dennis has been the realtor of our entire family both immediate and extended and will be the only person our family ever uses. You can rest assured he knows and loves his trade and will be the best realtor you and your family could ask for."

"Dennis Gullion took a personal interest in the sale and purchase of our homes.

He was by our side in every step of the process from staging to showings and the handling of multiple offers received in the fist 48 hours of listing! Upon completion of the sale of our home, he aggressively began the hunt for our new home. After several listings, he narrowed the search to a select few that went beyond our expectations and found us the perfect new home!"


"Dennis has helped us sale a home and find our forever home!

He is professional and friendly and will get the job done! He is knowledgeable and can answer any questions you may have! Not only is he your realtor, he goes far beyond in representing you as the owner and broker of the company!"
