After 18 years of practicing Illness Medicine
he realized that he was not making a difference in the patients' quality of life. In 1997, he entered the field of Anti Aging
Medicine (Interventional Endocrinology) and slowly ascended within the ranks of the main organization
(A4M). During his participation he became concerned about the credibility of the content of presentations and became
instrumental in enhancing the quality and scientific basis of the education. This led to his invitations to
lecture around the world on a number of his favorite topics; The truth about Growth Hormone, Diagnosing Adult Growth
Hormone Deficiency, Low Testosterone Syndrome, Cholesterol the Father of all Hormones, and most importantly; the Traumatic
Brain Injury-Hormone Dysfunction Syndrome (TBI-HDS). This last topic led Dr. Gordon to working on ESPN Outside
The Lines in January 2007, where he presented noted sports figures who had a history of multiple head traumas
leading to hormonal deficiency.

Originally trained in Family Medicine through Rush Presbyterian
St. Lukes Medical Center in Chicago, Illinois, Dr. Mark L. Gordon graduated with honors and with the highest residency award
for his level of skills and personal commitment to the patients and staff. In his progression into Interventional Endocrinology,
Dr. Gordon continues with this same commitment and enthusiasm that has now provided services to over 12,000 patients in 9
countries and 14 other states. He lectures nationally and internationally sharing his clinical experience in a straight-forward
manner that allows other physicians to tap into his personal database to enhance the optimal treatment of their patients.
