USANA Health Sciences formulates exceptional, science-based nutritional and personal-care products. However, inferior manufacturing can destroy even the greatest product formulations. For this reason, USANA manufactures its own nutritional supplements, and voluntarily meets pharmaceutical Good Manufacturing Practices (GMP). Pharmaceutical GMP standards are far more stringent than the food GMP requirements set by the U.S. government for supplements.

To adhere to the exacting standards of pharmaceutical GMP, and to ensure the quality of every product manufactured, USANA inspects all raw ingredients before they are mixed, tests the product during manufacturing, and performs a final analysis before any product is sent to the customer. USANA's Quality Assurance team keeps track of every detail, from careful testing and evaluation of raw materials, to meticulous product shipping and storage. Visitors to USANA's corporate headquarters can take a self-guided tour to see USANA's manufacturing process firsthand.

     I grew up on a farm in Western New York.  We mainly raised vegetables.  In fact, my
mother at 89 years of age, still runs the farm, which is about twenty miles from Niagara
Falls.  I’m still waiting to eat as well as I did back on the farm.  
     I remember having an interest in the human body from my youth, to the point of
memorizing Latin names of bones and muscles of the body from about age nine.  Living on
the farm, I learned how to work hard and be very active, and also what not to do for a living.
     I drifted through college, not sure of what profession to pursue until I graduated with a
degree in Philosophy.  At that point Uncle Sam told me what my profession would be: 
combat infantryman in Vietnam.  The military, and especially war, has a way of maturing
you, of giving you an appreciation for life and what’s important in life.  I subsequently met
and married my wife Peggy.  We have three sons.  I became a physical therapist, and then a
podiatrist, and ending up here in Texas in 1978 to set up a medical practice with a specialty
in sports medicine.  Soon afterward, I became a participant in the Harvard Health
Professionals Study ( ), headed by a well-known
researcher named Walter Willett.  I’m still a participant.  Through this study, I gradually
became interested in nutritional supplementation and its vital importance in maximizing
good health.
     Throughout this time, I pursued my interest in exercise.  I lifted weights from age 14,
took up running at age 27, ran my first marathon at 30, andstarted bicycle racing at 44. 
Because of the Harvard Health Professionals Study, I became convinced that
supplementation, especially antioxidants, could contribute significantly to the decreased
occurrence of many chronic degenerative diseases.  I also realized it might be possible to
gain an edge on my age-group rivals as we grew older if I pursued optimal nutritional
supplementation and a better diet along with my training regimen.  My dream since
youth was to win a major championship in an internationally sanctioned sport, but I found
out that my gift was not nearly as great as my peers, many of them having competed in
college, some on national and Olympic levels.  I was only good enough to compete well
on local and state levels.  What I did notice as we all aged is that most of them were slowing
down and I wasn’t.   My gifts seemed to be that of longevity and desire, not great
physical ability.  My speed peaked at age fifty, but it still wasn’t good enough to challenge
those gifted with wings on their feet and jackhammers for hearts.  My best times started
to slow, which is normal for a fifty-one year old.  I could not deny this --- the endurance
athlete's most merciless and just judge is the clock.
     About a year later, after due diligence, I decided that USANA products were my best
chance to help me to catch my competitors.  Although I have always been blessed with
good health, I noticed several significant things after starting USANA.  I began to sleep better. 
I had developed a painful shoulder over the years that audibly creaked while lifting weights. 
That completely disappeared after a few months, and  most significantly for an aging
competitive racer --- my recovery from hardtraining improved and my speed again increased. 
     My times peaked in my 55th year, and at age 55 I won my first Age Group
National Championship at the USAT Duathlon (bike-run ) competition in Carlsbad,
California, beating four world champions in the process.  At age 61, I finally won the
"big prize": an ITU Long Course Duathlon World Championship!  I was also awarded
Grand Master Duathlete of the Year in both 2006 and 2007.  I believe this is evidence that
these products can help optimize health as we age.
     When I started on the USANA Nutritionals, about six years ago, I was not interested in
offering these products to others beyond my family.  In October 2003 two things happened
in quick succession that I believe to be providential.  First, a friend and patient, whom I have
known for many years, came into my office and told me a most amazing story of her
remission from a virulent form of cancer that was considered incurable.  In fact, she was
given two months to live.  Soon after that, she experienced a complete remission, with no
trace of cancer in her body.  She came to me specifically to find out about the supplements
I was taking, as she knew my competitive nature and knew to maximize my racing potential
I would take only the best supplements.  USANA is only available through a network of
associates, so I was unable to provide her with these products.  Within a week or so,
I had lunch with a friend who offered me the opportunity to become a USANAassociate. 
Without hesitation, I said yes in stark contrast to a situation several years before, when I
was literally hounded for a year by a fellow physician to sell the supplements of a huge
well-known company.  I wouldn’t do thismainly because I knew USANA had a
better product and a better company.
     Now I am part of USANA for three main reasons: to be able to offer these products to
my patients and friends, for the personal growth that comes from being associated with this
great company, and to have fun presenting this opportunity to others,
(and yes—to make money as well).
