Come with me as we attend
Mother Nature’s Master Class

Hey, I’m David Smith (DrDave). I’ve made it my life’s work to study and better understand the natural world. This knowledge has mitigated the consequences of Traumatic Brain Injury (TBI) and Altitude Sickness and inspired a new way to manage Sleep Apnea.


I want to share them with you!

Discovering Nature’s Secrets for Preventing Traumatic Brain Injury

When Heads Come Together Book Cover

When Heads Come Together outlines the journey to solve many longstanding scientific mysteries, including the elusive scourge of Traumatic Brain Injury (TBI) that endangers contact sports and the brains of our warfighters.

“Why don’t clever people solve Traumatic Brain Injury?” an Army Research Lab member asked DrDave. Fourteen years and 25 publications later, DrDave pioneered “SLOSH Theory™” after studying Nature’s highly g-tolerant creatures such as woodpeckers, giraffes, and head-ramming sheep.

The results?

The Q-Collar™, the first and only device authorized by the FDA
for claims of prevention against TBI.


The SAGE Rebreather™, to mitigate TBI and altitude sickness and
revolutionize sleep apnea management.

Nature is my mentor™

“The breadth of my background in chemistry, physics, and medicine helped me to discover clever adaptations in the animal kingdom leading to multiple theories and medical devices that alleviate human suffering.” — DAVID W. SMITH, MD.

“BRAIN SLOSH Theory™” depicts a pathway to mitigate energy absorption into brains to prevent and even reverse TBI.

He and his wife, Ruthann, reside in Cincinnati and have five kids and a dog Vinny.

My pathway to discovery begins with a simple question… WHY?
