Our Staff

Tami Powell, PhD, CHT


I am the founder and CEO of the oxford recovery center. The Oxford Recovery Center became my mission after my own daughter had her life saved because of HBOT and her recovery was aided by all of our therapies. It will be my pleasure to make your time with us a pleasant experience as we do everything in our power to help you.
