ELEVATE YOUR HEALTH with the POWER
of PRECISION MEDICINE

The Right Treatment, for the Right Person, at the Right Time

Choose Optimal Health

Precision Medicine is personalized, proactive, predictive, precise, and preventive.

Precise and personalized biomarkers are analyzed specifically for you.

Evidence-based treatment protocols are designed to prevent the onset of chronic diseases and limit the progression of aging.

Your care is uniquely matched to you.

Dr Catherine Johnson offers a personalized assessment to review your laboratory and body composition biomarkers related to aging and metabolism. 

The goal is to isolate the unique signaling dynamics of your body that regulate blood sugar, fats, energy, manage infection and regulate cancer cells while balancing the oxidative stresses of aging on vital tissue.

These are dynamic, vital insights which enable an intentional life and healthspan, unique to each human being. 

“Thank you so much for being there for our family, Dr Catherine! We didn’t know just how much we needed you until you put all of the pieces together and we got the answers we have been looking for! J is feeling so much better! We are so grateful for your expertise!”

– H.C.

“I have always been fat. I tried every diet. Dr Johnson, you are the first doctor who taught me me how to eat, when to eat, what the medicines do, why we check blood levels and measure body composition tests. My body is losing fat! We need more doctors like Dr Johnson!!”

– L.B.

“OK, Dr. Johnson, I came into this thinking that I will just try it for a few months. Now, there’s no going back! I’ve been more focused and productive at work. I really needed to make a change. Thank you.”

– S.C.

“Wow. I had no idea that low testosterone could put me at risk for osteoporosis. I thought that doesn’t happen to guys until they’re in their 60’s. I need strong bones to play ball with my kids. Let’s do this, Dr. Johnson!”

Age Management Medicine

Preventive medicine focused on regaining and maintaining optimal health and vigor.

The changes we experience when aging related to body composition, energy, brain and sexual function are largely related to hormonal shifts.

At 20, we are invincible! At 30, vigor and vitality diminish slowly with focus and we have trouble keeping pace with our spirit to press forward. After 40, fat accumulates easily and workouts at the gym require more effort to achieve the same results we could achieve in our earlier years. Increasing forgetfulness, lack of focus, loss of skin tone and elasticity, thinning hair… and the clock keeps moving forward.

Age management medicine is the positive and proactive approach to lengthen healthspan and enjoy a more youthful aging process.

The right treatment, for the right person, at the right time.

Body Composition Analysis

Go beyond the scale and see what you’re made of. Break your weight down into muscle, fat, and body water to learn how to make positive health changes that matter.

The InBody 570 body composition analyzer goes beyond traditional body composition analysis, measuring fat, muscle, and total body water.

Total body water data can be divided into intracellular water and extracellular water.

These values important for understanding a user’s fluid distribution in medical, wellness and fitness contexts.
