Dr. Ralph Waldo

     Ralph Waldo, M.D. graduated from Indiana University with degrees in biology and psychology, following which he received an M.S. in Physiology and Biophysics.  In 1999 he obtained his medical degree from Indiana University School of Medicine.  Serving as Chief Resident during his final year of residency, Dr. Waldo completed his training in Psychiatry at the University of Cincinnati.  At U of C he participated in numerous research projects under the direction of Dr. Paul Keck, who is well known in the field of medical research.   Dr. Waldo became Board Certified by the American Board of Psychiatry and Neurology and practiced psychiatry for over four years at two major hospitals in Fort Wayne, Indiana, where he incorporated molecular medicine and biochemistry into his practice.  Finding that working in a hospital or large physician group setting was not conducive to his form of practice, he started his own private practice in 2011 utilizing integrative, biochemical, genetic and functional medicine as the basis for his practice.


     Dr. Waldo treats children, adolescents and adults using a multidisciplinary approach, including lab testing, to customize and more accurately guide treatment.  His emphasis is getting to a patient's core health issues in order to prevent, slow or stop disease progression.  His goal is to eliminate or reduce pharmaceutical medications when possible, and help a patient maintain or return to a healthy state.  He customizes treatment based on each client's specific needs as determined through a patient's health history, lab work and other appropriate testing.  Dr. Waldo treats the root causes of diseases and has a strong rate of success in stopping disease progression, preventing diseases from occurring and/or curing them.
