Dr. Rotana Steven Tek, D.O., A.B.A.A.R.M.

CEO and Medical Director

ABAARM Board Certified

Being a physician is a distinct privilege. We make patients feel better in the worst time of their lives, by maintaining the opportunity to nurture and keep them healthy and active. There is always an overwhelming satisfaction to help patients. It’s especially gratifying to hear them recover from an ailment that I was able to treat. It gives me pause to know that they have their life back. At the end of the day, it is about quality patient care. Listening to my patients concerns about their health is first priority. Understanding my patient’s experiences, memories, socioeconomic status, and career choices helps me to appreciate them as unique individuals.

After residency, I took on several jobs in both private and public sectors. Four of them were at Federal Qualified Health Centers in California where I oversaw many clinics and held several leadership roles including being a Medical Director and receiving commendation from Los Angeles County Supervisor for dedicated service to the affairs of the community and civic pride. While helping the underserved population, I have noticed patients —who have hormone imbalances— were under-diagnosed, poorly treated, and often overlooked because their hormones levels are “normal.” The “Normal Ranges” seen in every lab test rarely defines the the optimal level for the individual. It’s time to change that dogma and optimize hormone levels based on clinical presentation – that means how the patient feels and not so much on lab results. I think most of us know that our current health system has significant inefficiencies in terms of the numbers of tests and interventions that are not proven to help patients. Conventional medical practice is not treating both men and women who clinically have hormone imbalances. We need to develop a better system to take care of our aging population. That’s why I have created Alpha Hormones®: an ultra-convenient, simple to use medical platform for your health and wellness needs.

My speciality is my dedication to my patients. I truly believe that great care requires compassion, and a physician that listens to your needs and practices evidence based medicine. You deserve the best when it comes to your health, and you will find exceptional care with my practice.
