I started going to Dr. Denise Mark to balance my hormones in about 2001 and switched to Dr. Erik Dunning when Dr. Mark changed her practice. Dr. Dunning is excellent in optimizing health. He goes over each aspect of your blood work in great detail and explains what each marker means and how it effects your health. I appreciate how closely he fine-tunes bloodwork and vies to make your health as robust as possible. I will continue with Dr. Dunning forever!
