Rob Hentzen, PT, MBA

Chief Executive Officer, CEO


Upon graduation from the physical therapy academy in The Netherlands, Rob spent time in medical research before moving to the United States in 1987. After initially working as a therapist at a rehabilitation clinic in the Chicago area, he worked for a law firm in foreign recruitment and started a contract services business. Following this Rob developed and managed a private practice in Chicago. His interest in working for a larger organization drove him to Baxter International and later its spin off Caremark Orthopedic Services. While working as a Regional Director, Rob earned his MBA from Keller Graduate School of Business. During 1993 and 1994 Rob was the Area Vice–President for NovaCare’s Contract Services Division out of Denver Colorado. Following this he was recruited back to Caremark for a brief period after which he became one of the founders of Matrix Rehabilitation, an outpatient rehabilitation provider based in Dallas, Texas. Rob helped create a 200 clinic network in 14 states through acquisitions and start-up locations. During this time he also managed a third party payer network and several occupational medicine facilities.

After seven years and the sale of Matrix, Rob took the opportunity to join Millennium Rehab & Consulting Group and move to his wife’s native state of Iowa. Initially, as COO he helped grow the company by adding several outpatient clinics and expanding the services in long-term care and home health. Currently as Part-Owner/CEO, with a passion for business development, Rob plans for continued steady growth through the development of Millennium’s associates and customer relations.

Her 22+ years of experience in treatment delivery, program oversight, and rehabilitation program administration gives a very valuable and broad perspective in the delivery of Occupational, Physical and Speech Therapy in Iowa's most rural communities. Holly understands the nuances of delivering rehabilitation in health care shortage areas and the uniqueness of therapy delivery in many settings including critical access hospitals, home health agencies, direct home visits, skilled nursing facilities, daycare centers, outpatient clinics attached to skilled nursing facilities, rehabilitation agencies and at free standing clinics. With Millennium, she is using this knowledge and understanding of the unique differences, coverage criteria, documentation requirements and administrative rules applying to each of the above settings to develop and expand the programs and services available to Millennium Therapy communities and clients.

Holly is a current Board Member of the Iowa Physical and Occupational Therapy Licensing Board. She values her position and the opportunity to make a difference in the oversight of Occupational and Physical Therapy practitioners. There are many changes happening in health care right now and she seeks regulatory rule input to ensure practice rules apply to and make allowances for the nuances of providing therapy services in all Iowa settings.
