At the risk of sounding redundant, may I highly recommend this practice? I feel like I have totally new DNA, the transformation in my health has been amazing these last few months. And I went to all kinds of doctors in my network prior to seeing Dr. Hester and his team. I've never felt better. Experts, caring, focused, results-oriented. go see the good folks at CEI.

Lady at the reception desk could not hear what I was saying she kept asking me to repeat over and over. "We do not take insurance" right on my face before we even talked about anything else, unfriendly.
