Jon Sisenwein - Living the Boulder Dream, Helping You Find Yours

Jon Sisenwein knows what it means to find the right home—because he’s done it. With over eleven personal real estate transactions across three states, Jon’s experience goes far beyond the typical agent’s. From buying, selling, and renovating properties in bustling cities to discovering his dream lifestyle in Boulder, Jon has lived through the excitement, challenges, and opportunities that real estate brings. This first-hand experience means he understands what it takes to make every move smooth and successful for his clients.

​

Originally a New Yorker, Jon once believed that city life was the only life. But after moving to Boulder, he quickly discovered something remarkable—a place where community, opportunity, and the beauty of Colorado’s outdoors align perfectly. Now, Jon and his family live what he calls “the Boulder dream”, and he thrives on helping others achieve that dream too—whether it’s relocating, upgrading, or selling with confidence.

Born into a family of real estate developers, brokers, and insurance professionals, Jon’s passion for real estate started early. Pair that with his extensive professional background—first as a successful Creative Director in the New York advertising world and later as a startup Founder—and you’ll find a Realtor® who brings creativity, strategy, and unwavering commitment to the table.

​

Clients trust Jon for his unique blend of market expertise, negotiation skills, and ability to truly understand their goals. He approaches every transaction with the belief that buying or selling a home isn’t just a process—it’s a milestone. Whether you’re looking to navigate Boulder’s competitive market as a buyer or maximize the value of your home as a seller, Jon is the trusted guide you want on your side.

​

Jon lives in North Boulder with his wife, two kids, and their loyal (and very needy) dog. He’s a Certified Real Estate Negotiation Expert (RENE), a licensed Realtor® in Colorado, and an active member of the Boulder/Longmont Area Realtor® Association. Outside of real estate, Jon’s community involvement includes serving on the Watershed School Board of Trustees and leading local homeowners associations. An avid CrossFit enthusiast, Jon brings the same energy and focus to his clients that he does to his personal pursuits.

About
Get to know me

Jon is fantastic to work with - he is responsive to inquiries and questions, thorough in his preparations, and not afraid to ask the hard questions and go to bat for his clients. We bought our first home with his guidance and there was a lot for us to learn - we have come out the other side feeling educated and supported. I wouldn't hesitate to work with Jon again or to recommend him to his future clients.
