Accessible Systems Owners & Office Staff


Accessible Systems Owners (left-to-right Nathan, John, and Marty)

Nathan Colburn, Accessible Systems Owner, CAPS

Nathan joined the company home modifications 15 years ago after his cousin became paralyzed over in an accident. This experience was eye-opening, to say the least. He quickly realized that there would be a growing need for home accessibility solutions, as families age and adapt to various health issues- and prefer to do so in the comfort of their own homes. Nathan attended the Ambassador University, before moving to Colorado with his family. If you have questions about ownership opportunities as we expand to more territories, please call Nathan directly at 720.358.8150, or send him an email (preferred) at [email protected]

He has extensive experience in accessible lifts and ceiling lifts, and is married to an occupational therapist. In his free time, he loves to go Jeeping with his family just about anywhere in the gorgeous Rockies. If you are interested in adding the luxury of an elevator, or the convenience of a ceiling lift to your home, please don’t hesitate to call Marty to set up your free, in-home consultation at 720.358.8170 or via email (preferred) at [email protected]
