Dianna was recommended by another agent that moved away to Dallas. I couldn’t have been any luckier in having her as my agent. My situation was going to be a strain on her because of an on going divorce and having to deal with 2 parties and trying to keep both sides happy. She went above and beyond in our every needs for this sale to happen. I can’t speak for my other half because she was making it very difficult for Dianna. Being the champ she is though she pushed thru it and made it happen. I am so happy she kept her composure throughout this ordeal. She always kept in the loop of anything that came up. Always on top of things Do not ever let this agent go elsewhere! She is awesome.

By far the best experience we've had, Dianna went above and beyond our needs to help us with this buying process. She was very understanding and patient with us, and always took the time to answer any and all questions we had. Especially with her expertise and communication, and her truthfulness really helped us ease the stress of choosing the right home for us. So happy we went with Dianna Mares and Keller Williams if we ever decide to sell we will definitely be back.

Relocating from out of state can be intimidating especially on a short time frame but Dianna made this process incredibly smooth and enjoyable! From first contact with Dianna we knew that we had found an amazing realtor to work with. She was always responsive to our messages and kept us informed during the time leading up to our one day in town to look at homes. Her dedication to helping us find our new home was more then we ever expected! The day went smoothly looking at homes resulting in us finding our dream home. Dianna was so patient with us and our almost two-year-old son throughout the long day. Once we returned home, she was there for us every step of the way guiding us in the process of long distance home purchase. Dianna exceeded our expectations throughout this process. From the first house we saw to closing day she kept us informed and maintained excellent communication. Dianna’s passion and commitment to not only her job, but to us, as clients really sets her apart. Highly recommend working with Dianna!

Dianna was terrific in every way. She made the difficulty of moving from out of state less stressful than I thought it was going to be. The videos of my new home were very helpful in making my decision to purchase the house. She continues to offer her assistance in making my new home ready for me to move in. She is a true professional and so easy to work with.

Dianna was an awesome agent. My fiancé and I are so glad we found her, we would not have wanted to do this with anyone else. She was honest, kind, motivating and she really cared about what we wanted. We have actually invited her to our housewarming party and will recommend her to everyone we know. There were times when we wanted to give up and she kept pushing us. The only reason we have the house now is because she kept sending emails of new listings. Great at what she does. Couldn’t be happier! Awesome is the only word to describe the experience. We found a home in a matter of weeks. So happy!

Before I moved to San Antonio from Oregon I talked to several agents in the area. None of them gave me that "good" feeling. Then I found Dianna Mares and knew instantly that I was in good hands. She had several homes lined up for me to see when I got to Texas. She helped me find the home I was looking for and oversaw each step from beginning to end. When I decided to sell that house she was the only person that I considered. Dianna Mares is flawless in her strategies and advertising. She instantly found us a buyer and walked me through the entire process once again. When I buy another home she will be the only person I call. If you are looking for someone that you can trust, someone that truly has your best interest at heart then look no further! Dianna Mares is the only person you need and should call. I promise you will be in great hands! Dianna, from the bottom of my heart I want to thank you for everything. You are the best!

Dianna Mares was a professional realtor from the moment I hired her. She impressed me with professional pictures of my home. She had a binder put together of homes sold in my neighborhood, along with the prices they were sold for. She helped me price my home wisely. When I was requested to make repairs on my home, not only did Dianna know who to call for a good job, but she knew who was reasonable as well. Being an active single Mom to two children, I had a busy schedule. Dianna Mares was available when I needed her. If I could not be at home for an estimate from a worker, I knew I could count on Dianna to show up for me, and relay the information back to me. This is a rare quality in a realtor. It’s not in their job description. Dianna went above and beyond my expectations, and I would love to work with her in the future again if necessary.

Dianna Mares is by far the best Realtor I have ever worked with. She took care of everything and was always quick to respond to questions. While we were looking at houses, she was great at giving us ideas and could see beyond negative characteristics of a home and offer ways we could improve or utilize spaces. She was always optimist and her bubbly personality made it a pleasure working with her. Dianna was attentive and hardworking and I highly recommend her.
