MEET OUR AGENTS

John Gassen

I like being outdoors with my family - my wife and three kids. Whether doing activities like hiking, going on walks, or simply sitting on the back porch drinking coffee or iced tea, hanging out with my family is my favorite. We have two dogs, three goats, and who knows how many chickens. I grew up in Mustang but graduated high school in Union City.

  • "John was incredibly helpful. In being a first time home buyer and from out of the state, it was super important to find someone that could give us guidance and who we could trust. He always made himself available to us, in spite of our time difference, and walked us through every detail of home buying or question that came up. He has given us great referrals to businesses in the area and still will pick up the phone when we call to ask about tornadoes or other random questions that come up since becoming homeowners. We are so grateful to John and all the help he has given and continues to give us. If you’re looking for a house in Oklahoma metro area, John’s your guy!"

  • “John went above and beyond in every stage of the home buying process. He advocated for our needs wherever applicable, be it with the listing agent, our lender or anywhere else we needed him to do so. He was always extremely kind, making sure to take the time to explain everything thoroughly as well as answer any questions we had. Absolutely 100/10, would recommend for anyone looking to purchase a home, especially first time home buyers.”

    Sarah Stevens

  • John was so helpful in the buying and selling process of our homes! We are second time buyers, but first time sellers. He made the process smooth while also providing us with all of the information needed to make the best decisions possible. John was always extremely responsive, and answered any and every question we had. He also provided a lot of really great resources and referrals when it came to improvements that needed to be done. We can't recommend him enough!!!

  • John was a joy to work with. We were shopping from out of state, and he included details when we did virtual tours that we wouldn’t have even thought to ask about (what the neighborhood looked like driving in, the quality of the neighborhood streets, the direction the house is facing, what portions of the house would be in the sunlight throughout the day, etc). He also worked hard to arrange several listings in the span of two days while we were in town for a short while. Highly recommend!

  • John has been so much help with us buying our first house. He was very available with any questions we may have had and helped simplify some of the harder things that new homebuyers may not know/be aware of! Would recommend him to any of my family & friends.

  • "We can’t say enough good things about John Gassen! He helped us sell our house and buy another one, and somehow made one of the most stressful processes feel easy. Behind the scenes there were definitely challenges, negotiations, and moving parts, but John handled everything like a pro. His communication, strategy, patience, and flat-out mad skills absolutely killed it from start to finish. He always stayed calm, kept us informed, and fought for what was best for our family. If you’re looking for a realtor who genuinely cares and knows how to get things DONE, John is your guy. We are so thankful for all his hard work and highly recommend him to anyone buying or selling a home!"

    Michelle Walker

  • "From buying to selling, we've now done both with John by our side. Moving can be stressful enough. Having a knowledgable, trustworthy, and reliable agent on your side makes that load lighter. We HIGHLY recommend John. He’s an amazing agent and an even better person!"

    Brayden Lovelace

  • "John was an excellent guide through our house shopping adventure. He is extremely knowledgeable, we were looking at buying through different mortgage paths and he was able to give us insight on how different properties might be difficult and how others might be easier. He was in constant communication with us when the sellers were taking a longer than anticipated. He was patient at each showing he took us to with our 3 small children. Overall I will be recommending John to everyone I know looking to buy or sell property."

    Amy Jacobs

  • "We reached out to John Gassen about a year ago, and we knew we wanted to buy a house with his help! He is extremely professional and very knowledgeable when it comes to home buying. We have just recently finished the home buying process, and we found the perfect home thanks to John’s amazing skills. He made sure that we understood every last step of the process, and I feel very grateful for that. We will most definitely be reaching out to him for any future home buying needs! I highly recommend him to anyone else looking to buy or sell a house!"

    Taylor Rowe

  • "John helped us sell my brother's house a year and a half ago. He was really on the ball and so nice and easy to work with. He made it a very pleasant experience under the circumstances. Thank you, John!"

    Debbie Priebe

  • "John was incredible to work with! He made the home buying process super easy and stress free from the beginning to the end. He made sure to take time to explain things to us and answer any questions we had (we had a lot as we were first-time home buyers). We told him things we wanted in a house and he found us the perfect home! We can’t wait to see all the memories we will make in our new home and can’t thank John enough! We HIGHLY recommend him to anyone buying or selling a house!"
