We'll Help You Keep Up With Life's Best Moments

As dads who dove into the kiddie pool a bit later in life, we quickly learned that keeping up with our dynamo kids means staying sharp and agile for many years to come.


Our mission: to give you the health advantage you need for a longer, stronger life.

Meet Casper: A Danish-American scientist, immune system expert, a PhD in Immunology, and dad to four kids under seven. (Nobel Prize in survival pending.)


Studied at Copenhagen University and later under Nobel Prize-winning Dr. Ralph Steinman at Rockefeller University, who discovered dendritic cells, which organize immune responses like Casper organizes bedtime chaos.


At Celgene, he tinkered with stem cell treatments while dodging toy trucks. Loves exercise, good food, and natural supplements for mind-body optimization.

"Proof that you can juggle Nobel-worthy work and a zoo-like home life while staying healthy. (Results may vary. Sanity not guaranteed.)"

Meet Bart: lifelong fitness geek, lucky husband, and proud dad of two bundles of energy. After serving in the military, Bart worked with the world’s biggest contractors in construction technologies for the drilling industry.


Despite being fit most of his life, he was blindsided by a heart condition diagnosis at 52 during a period where he ignored his health. This wake-up call led him to take decisive action.


Realizing time was slipping away faster than a dad joke at dinner, Bart leveraged his fitness experience to craft a winning approach to health. The result? A healed heart and a vibrant new lease on life!

"I realized that staying healthy wasn't just about having six-pack abs. It was about being there for family moments that matter, although becoming a ripped dad is a bonus!"
