Welcome to High-Tech & High-Touch where cutting-edge advancements in medical science merge with a personalized approach tailored to your unique needs.

After years of researching the best practice technologies with national thought leaders in chronic disease, Dr. Holthouse MD designed an innovative 12-month mentorship program that revolutionizes the way we approach aging and the chronic diseases of age. Based on the 9 published pillars of aging known in medical science, we are excited to announce Precision Age Reversal (PAR-1) – a visionary initiative built for those who are wholeheartedly committed to unlocking high-performance health and elevating quality of life.

Why Dr. Holthouse Created The Precision Age Reversal (PAR-1) 12-Month Program:

Precision Age Reversal (PAR-1) is not simply about living longer but living better, avoiding the suffering from avoidable diseases as we age. If you want to put off or avoid what happens by default to most people after they hit their 70s with chronic diseases taking over, creating a poor quality of life, then PAR-1 is for you! New discoveries and advances in genetics, testing and molecular biology have made it possible to look at how we age at a cellular level. Imagine having the power to not only slow down but frequently reverse the aging process at the cellular level—this means a direct impact on curbing the top 10 causes of death by slowing tissue and organ diseases. It's a game-changer for your health and longevity!
