About me

Jack Rentz, MD, is passionate about helping his patients become pain free. Board-certified in anesthesia and pain medicine, Dr. Rentz came to Colorado to help patients get back to the fantastic Colorado lifestyle that drew him and his family from their southern roots to the Rocky Mountains.

After completing his undergraduate degree at the University of Georgia, he attended the Medical School of Georgia where he received his doctorate. Dr. Rentz then moved to New Orleans where he completed his residency in anesthesiology at Ochsner Hospital. There he was honored to serve as chief resident before receiving a fellowship at the prestigious Pain Medicine Center at Texas Tech University in Lubbock, TX. After visiting Colorado with his family, Dr. Rentz decided to move to the Metro Denver area to help patients get back to the things they love to do in this beautiful area.

Dr. Rentz is excited about serving his patients at his practice,Denver Diagnostic Pain, where his goal is to provide the highest level of care to those who entrust him with their health. Each patient that comes to his practice is on a journey to improve their quality of living and choosing to partner with Dr. Rentz along the way. This is a responsibility with which he is honored to be trusted.

When he’s not helping patients, Dr. Rentz can be found skiing,hiking, camping and loving the Colorado outdoors with his wife and two kids. He is a man of faith, which helps him as he treats his patients as well as navigates daily life.
