For nearly 30 years, I served and protected the people of this community as a law enforcement officer. When I retired from the police department in 2014 and transitioned into real estate, my mission stayed the same: serve people with integrity, honesty, and dedication.
I'm Mark Wiesemann, Realtor with RE/MAX Heritage, and I believe buying or selling a home is about much more than a transaction. It's about helping people navigate one of life's biggest decisions with confidence and peace of mind.
My law enforcement career taught me how to listen, communicate clearly, solve problems under pressure, and always put people first. Those same values have become the foundation of my real estate business. Whether you're buying your first home, moving up, downsizing, or selling a longtime family property, my goal is to make the process as smooth and stress-free as possible.
Since entering real estate, I've helped more than 500 families throughout Lee's Summit, Blue Springs, Independence, and the greater Kansas City area achieve their real estate goals.
Along the way, I've been honored to earn the RE/MAX Platinum Club Award, induction into the RE/MAX Hall of Fame, and the prestigious RE/MAX Lifetime Achievement Award. While I'm grateful for those recognitions, the true measure of success is the trust my clients place in me and the relationships that continue long after closing day.
Many of my clients become lifelong friends, and referrals from past clients remain the heart of my business. To me, there is no greater compliment than having someone recommend me to their family, friends, and neighbors.

When I'm not helping clients, you'll find me spending time with family, cheering on local sports teams, supporting organizations like Children's Miracle Network, Answering the Call, and Special Olympics, or sharing a dad joke and a pair of questionable socks.
If you're looking for a Realtor who will work hard, communicate honestly, and treat your move as if it were his own, I'd be honored to help. Let's start the conversation.


I specialize in Lee's Summit and Blue Springs, and I help clients throughout the greater Kansas City metro. This is my community, and I know it well.
Absolutely, and I love it. I'll walk you through every step in plain language, answer all your questions, and make sure you never feel rushed or in over your head.
Real estate commissions are negotiable and are discussed and agreed upon upfront, so you'll always know exactly how everything works before we move forward. I'm happy to explain the details when we talk.
After 29 years in law enforcement and more than 500 transactions since 2014, I've built my business on one thing: putting people first. You get honest answers, steady communication, and someone who genuinely cares how your move turns out. That's a promise.
Still have questions? That's what I'm here for. Reach out anytime and let's talk.
