Theodore Steven Roosevelt

I decided to become a physician in the fifth grade after reading John Gunther’s book, Death Be Not Proud. This started me on a journey with ups and downs, wins and losses, joy and sadness, but I regret nothing of what has transpired. I started working in health care when I was in high school, doing everything from insurance billing for a GP, to being a pharmacy delivery clerk.

I received my undergraduate degree from UCLA (cum laude BA in Zoology, a history minor, and an 8 time All American on the Bruin fencing team) before being awarded a NIH scholarship to simultaneously attend graduate and medical school at the University of Utah in Salt Lake City. I graduated summa cum laude with a PhD in Anatomy in 1972, and magna cum laude with an MD in 1974.

I was recruited by Barnes Hospital in St Louis, MO for my internship and residency, majoring in Internal Medicine. During my study, I received house staff honors.

I returned to Southern California, joining one of the top endocrine training programs in the US at Harbor-UCLA Medical Center. In graduate school and during my fellowship, in addition to my clinical studies, I conducted basic research on adaptation to altitude, corticosteroid effects on brain metabolism, and developed the first radioimmunoassay for beta-endorphin.

I am currently board certified in both Internal Medicine as well as Diabetes, Endocrinology, and Metabolic Disorders. I began my private practice in my former hometown in Southern California where I practiced for over 14 years. I held a number of hospital executive positions and founded a treatment center for patients with diabetes, which is still in existence.

During this same time, I attended and graduated from law school at Western State College of Law, and specialized in appellate practice.

In 1993 I moved to Boise, seeking to get away from the hustle and bustle of the big city and have owned my independent medical practice for over 20 years.

I’m the proud father of four wonderful children and ten grandchildren. My interests include skiing, hiking, hunting, and fishing. I have earned black belt status in the Japanese sword arts of kendo and iaido, as well as goju karate. I golf (badly) and if I have any spare time, I’m sharpening my educational experiences and try to play the ukulele.

I always try to bring my best game to your medical problems and treat you as I would want a member of my family to be treated.

I was born and raised here in Boise, ID. Growing up I was constantly outside. Whether I was riding to the Natatorium on my bike or building forts in the Boise foothills, I was always up for an adventure. I attended Boise High School where I earned a Lifetime Achievement Award for being a four year lettermen in the sport of women’s fast pitch softball. To this day, if I’m not at work, I’m often on the softball field. I also enjoy playing soccer, volleyball, and boxing, as well as hiking with my two dogs and cycling through town.

My mother has been a nurse my entire life. One day while visiting her at work a patient suddenly started having a violent seizure. Seeing my Mom jump into action and take care of the patient while, somehow, simultaneously calming the patient’s family was amazing. I knew, at that moment that I wanted to be in the medical field. It wasn’t until after volunteering at a local hospital and meeting with various medical professionals, however, that I set my sights on becoming a physician assistant.

I graduated from Idaho State University with a Bachelor of Science degree in zoology and immediately went into their graduate Physician Assistant Studies program. Throughout the intense two year program you learn a lot and you get to experience just about every field of medicine. While there were many interesting topics, there was one field that stood out to me: endocrinology. During my second year of PA school I was able to do two rotations with Dr. T. Steven Roosevelt at Idaho Diabetes and Endocrinology Assoc. Dr. Roosevelt taught me the ins and outs of diabetes management and thyroid treatment, as well as the diagnosis and treatment of other rare endocrine disorders. Through my two rotations my love of all things endocrine only grew. After graduating with a Master of Science in Physician Assistant Studies I then accepted a position with Dr. Roosevelt here at Idaho Diabetes and Endocrine Assoc.

After a few years I got the itch to explore and moved to the state of Utah. While living in Salt Lake City I worked in Family Medicine and while I appreciated the opportunity to do something new, I really missed working in endocrinology. So after about three years I decided to move back to Boise and I was relieved to discover that there was still a position available for me here at Idaho Diabetes and Endocrine Associates.

I grew up in the Boise area and in my younger years, my life revolved around athletics. I played baseball and soccer year-round and also sprinkled in some very mediocre basketball during the winter. After graduating as valedictorian from Meridian High School, I attended Northwest Nazarene University. There, I competed in baseball, cross country, and track and field and graduated Summa Cum Laude with a Pre-Physical Therapy degree in 2009.
A severe shoulder injury had catalyzed my path to Physical Therapy school, and I entered the Idaho State University Doctorate of Physical Therapy program. Since I had been granted additional NCAA athletic eligibility, I also competed for ISU in cross country and track and field. However, a perfect storm of illness and overtraining led to profound endocrine dysfunction while in PT school, which resulted in a dramatic shift in my scholastic and vocational goals. I graduated with my Doctorate in Physical Therapy in 2013, but I had already fallen in love with metabolism and biochemistry; I never perceived a sense of finality in regards to education. While practicing as a Physical Therapist and earning an additional certification as a Certified Strength and Conditioning Specialist (CSCS), I concurrently took additional pre-requisite courses with the goal of attending PA school. I graduated in May of 2020 with my Masters of Physician Assistant Studies from the Yale School of Medicine and I am excited to utilize my educational and life experiences to positively impact the metabolic health of my patients.
I truly have a passion for people and nothing edifies me more than helping individuals optimize quality of life. When I’m not in the clinic, I lead the Youth Ministries at Heritage Bible Church and also teach a non-denominational Christian release time course called Launch Pad at Mountain View High school. I enjoy running, CrossFit, Ultimate Frisbee, and any sport that doesn’t involve wearing skates! I am married to my beautiful wife, Christa, who is a registered nurse, and we have a 3 year-old daughter, Mia. They are unequivocally adorable, and I am unequivocally blessed in so many ways. I feel like a living testament of God’s faithfulness despite a rather circuitous route to becoming a Physician Assistant. I am so grateful to be on staff here at Idaho Diabetes and Endocrine Associates and am looking forward to helping you “add life to your years.”
