About Jon Sisenwein

Before ever becoming a licensed Realtor®, Jon had successfully lived through eleven real estate transactions in three states. Some call it excessive moving, he calls it passion.

Born into a family of real estate developers, brokers and insurance agents, Jon has made a habit out of buying, fixing and flipping homes. He'd be thrilled to use this knowledge to help you achieve your real estate goals.

Jon began his career in New York as an advertising Copywriter, ultimately working his way up through the ranks as a Creative Director at some of the best-known ad agencies in the world. Leading creative teams on fortune 500 brands, he somehow found his way to Colorado. Since then, Jon has participated in the startup world as a Founder and discovered his passion for residential real estate.


Jon lives in North Boulder with his wife, their two children and one very needy dog. He received his BS from the State University of New York at Plattsburgh. He's a licensed Realtor® in Colorado, Certified Real Estate Negotiation Expert (RENE), active member of the Boulder Area Realtor® Association and a member of the Sanitas Terrace Homeowners Association Board of Directors.

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.
