About John
Originally from Delaware, I relocated to Central Florida in 1998 to work for Walt Disney World where I met my wife and started my family. With years of customer service and professional experience, I began my real estate career in 2004 and have helped multiple families find their dream home through the highs and lows of the market. Central Florida is a great place to live and I can help show you some amazing properties and welcome you home!

John Callahan was everything we could have hoped for in a realtor and more. From start to finish, he was professional, responsive, knowledgeable, and truly committed to helping us through the process. John made us feel supported every step of the way. He listened to what we needed, gave honest guidance, and made sure we always felt informed and confident. His attention to detail and willingness to go above and beyond made a stressful process feel much easier. What stood out most is that John didn’t just treat us like clients. He treated us like people he genuinely cared about. By the end of the process, he became more than our realtor - he became our friend. We are incredibly grateful for everything John did for us and would highly recommend him to anyone looking for a realtor who is trustworthy, dependable, and truly invested in his clients.

John Callahan was a lifesaver for our home search in the Windermere area. John's deep local market knowledge of the area, helped us find a beautiful home which we are exited about. John was also incredibly patient and walked us through every step of the process, making us feel like we were with a trusted friend rather than a mere transaction. There were some issues with the house but John helped home improvements contacts who worked quickly to fix the issues. I want to take this opportunity to state that John is not only a great realtor but ended up being a friend at the end of this purchase. I will strongly recommend John to my family and prospective home buyers.

John is an amazing agent. He helped me with the home buying process. Since this is my first home, he negotiated the price that was in my budget. He also gave me tips in what I can do to make my new house better. The whole home buying process was amazing and I would definitely recommend him to friends and family.
