Meet Our Fearless Team

Chairman / CEO

Carl Mittendorff

Senior care has been a passion of Carl’s ever since he watched his grandfather, a decorated WWII Marine Corps Tank Commander, pass away in a Medicaid bed at a nursing home. At the time, Carl was a young man just starting out in business, and there was only so much he and his family could do to care for “Papa” with the resources the family had.  Carl’s mother, a long-time single mother, working hard to support her family, acted as Papa’s caregiver in the evenings while she worked her full-time job during the days.  Eventually, Papa’s care needs were too severe, and the family had to move him into a state-funded facility.  Soon thereafter, Carl devoted his career to serving seniors.

Carl knows that his purpose in life is to serve.  In his heart, this extends towards his employees, the residents they serve together, and their families. He is a firm believer that his residents’ and employees’ lives should be as engaging and fulfilling as possible; he genuinely loves carrying out his purpose of service both professionally and personally.  Carl routinely serves as a speaker and industry expert in seniors housing conferences, newsletters, and other media.

Carl is committed to bringing the Colonial Oaks culture of loving care and services across the nation through strategic acquisitions and new development. His commitment is to marry the unmatched Colonial Oaks Senior Living 40-year history and longevity of yesterday with the research, innovation, and technology of tomorrow. This isn’t the first time that Mittendorff has led the growth of a senior living company. In fact, he spent the prior decade leading the growth of another company from 4 communities to 38 communities, eventually operating across 21 states. Colonial Oaks is uniquely poised to embrace new innovations in eldercare while building upon its 40-year foundation of loving and serving seniors.
