About Jon

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 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. Working his way up through the ranks at some of the best-known ad agencies in the world, he somehow found his way to Colorado. Since then, he’s participated in the startup world as a founder and finally discovered his real passion. Jon now lives in North Boulder with his wife, two children, and one very needy dog.

Jon received his BS from the State University of New York at Plattsburgh. He’s a licensed Broker Associate and Realtor® in Colorado and former President of the Sanitas Terrace Homeowners Association in North Boulder.

"My daughter is a CU student who found Jon and we're so glad she did. Jon did a great job maintaining a constant channel of communications with my daughter in Boulder and me in Atlanta. In addition to helping us buy the perfect apartment for our needs, he also pointed us towards affordable financing and home improvements. Best of all was Jon's easy-going but all-out approach. He got things done while making the buying experience enjoyable."

"Jon Sisenwein went above and beyond our expectations. I call him a "Super Broker." Without Jon Sisenwein we would have never found our house. The Boulder market is tough! Jon consistently got us in to see listings before the open houses, pulled comps so we could evaluate the best offer, and was able to negotiate an offer within our budget but over ask that convinced Seller's broker to take the property off of the market before the open house! He is extremely communicative and responsive via text, phone and email, and is a WEALTH of knowledge on the Boulder area. He knows the neighborhoods, the schools, the people at the title company, the lenders and even the contractors to line you up with if your home needs work. I HIGHLY recommend him. Coming from the NYC area we had no idea Boulder would be so tough. Jon was a dream and got us our dream house.!"

"It was a pleasure working with Jon as my realtor. He is patient, super knowledgable, and helped me find the perfect home. He walked me though every step so I knew what to expect and was very responsive to every text and email I sent him. I highly recommend him to anyone searching for a home in the Boulder area.."

"We have recently worked with Jon to buy our first property. He is knowledgeable, attentive, communicative, supportive, and incredibly generous with his time. We had hiccups throughout the buying process, but with his guide and support, we were able to successfully move through. We highly recommend him"

"Jon is super knowledgeable about every aspect of buying a property. He proved to be very patient and responsive, and went way out of his way to answer all my questions and ensure I got the best arrangement possible with my condo."
