What I do best
What clients say about working with John
“Working with Colin was an absolute pleasure from start to finish! As first-time sellers and buyers, we were a bit nervous, but Colin made the entire process smooth and stress-free. He not only helped us sell our empty lot but also found us our very first home – all while we were adjusting to life with our newborn baby! His knowledge of the market, attention to detail, and patience with our questions were invaluable. Colin took the time to understand exactly what we were looking for and worked tirelessly to find the perfect home for our growing family. We truly couldn’t have asked for a better realtor. Highly recommend Colin to anyone looking to buy or sell – especially if you’re navigating the process with little ones in tow!”
“At first, I honestly didn’t know what to expect working with John… you hear all kinds of stories in real estate and I was ready for another person with a big ego, too busy to pick up the phone, or just talking numbers with no real respect. But man, John is the exact opposite. This guy is amazing. No ego, no games just real, straight-up respect for everyone he deals with. I don’t know how he’s not #1 in the world at what he does. Every single time I called, whether it was me or one of my buyers, he answered the phone. That type of consistency and professionalism is rare these days. If you’re looking for someone who treats people the right way, goes the extra mile, and still stays humble, John is the one.”
“John Colin is hands down one of the best realtors in Southwest Florida! He is professional, knowledgeable, responsive, and truly cares about his clients. He made the entire experience smooth and stress-free, always taking the time to answer questions and make sure everything was handled the right way. If you’re looking to buy or sell a home in SWFL, I highly recommend reaching out to John. You won’t find someone who works harder or cares more about helping you achieve your goals.”
“Colin helped me get an absolute STEAL on a home in San Carlos Park that is now my fourth rental property. He’s honest, professional, and truly cares about his clients. As someone who has been through the buying process multiple times, I really appreciate working with an agent I can trust. I’ll definitely be using Colin again and highly recommend him to anyone looking to buy or sell!”
