We Live Here, We Work Here, We're Here For You!

Hi, my name is David Thelen and I've been working in real estate for as long as I can remember. While growing up just outside of Houston in Katy, TX my step father was a New Home Builder Representative within the Katy area. You can say that this put the real estate bug in me and it hasn't wavered since. I am lucky enough to have turned my personal passion into my career and have spent the last 7 years helping others find their home while also finding that perfect buyer for a home. You've probably heard that turning something you love into your career means you'll never have to work a day in your life. I completely embrace that mindset as I work all hours of the day and every day of the year to help others find and sell their homes. Real estate is about the details and I encourage all my clients to research potential neighborhoods, schools and area amenities that work for you. The Houston/Katy area has so much to offer and I truly believe everyone's dream home exists closer than you'd think. I graduated from the Katy High School and Champions School of Real Estate. I am a Certified Negotiation Expert (CNE.) I think my favorite accolade is the number of prior clients who have hired me to help them buy or sell multiple homes over the years. Knowing that you've left behind a positive impact is important to me and how I run my business. So, why do I work in real estate, aside from loving it? I do it for my family. I have a stunning wife, two children running around the house and a pet named Teal. We don't leave the state of Texas much and why would we when there are millions of acres to fish and explore!
