Our founder

Daniel Hesler, MD, FASA

Founder, Carbon Stewardship Solutions · Regenerative Farmer · Chief of Anesthesiology · Public Health Officer

Dr. Hesler is a board-certified attending anesthesiologist with nearly 20 years of experience — and the first documented emissions-neutral anesthesiologist. He founded Carbon Stewardship Solutions at the intersection of three passions: clinical medicine, regenerative agriculture, and public health.

His mission is straightforward: to help hospitals, ASCs, and health systems reduce their environmental footprint in ways that are practical, clinically sound, and financially beneficial — starting where the opportunity is greatest.

The CSS origin story

Where three worlds meet

Carbon Stewardship Solutions didn’t emerge from a boardroom or a consulting firm. It came about because Dr. Hesler lives at a genuinely unique intersection — one that very few people in American medicine occupy.

Growing up a lifelong farmer and outdoorsman, Dr. Hesler developed a deep passion for sustainability and the stewardship of natural resources long before he ever entered a medical school classroom. That foundation never left him.

As his career in anesthesiology advanced and his understanding of public health deepened, Dr. Hesler found himself in a position few others could occupy: someone who understood the science of anesthetic gases, the economics of healthcare operations, the biology of soil carbon sequestration, and the public health consequences of greenhouse gas emissions — all from lived, practical experience.

It was that combination that allowed him to connect the dots: regenerative agriculture could play a direct role in helping hospitals become more sustainable. Carbon Stewardship Solutions was built to make that connection a reality — for any hospital, ASC, or health system ready to lead.

Creation stewardship

The deeper “why” behind what we do

For Dr. Hesler, the push toward sustainability goes beyond regulation and cost savings. It is rooted in a belief that we have an obligation to care for the natural world entrusted to us — and to leave it in better shape for those who come after. This conviction, drawn from his Christian belief in Creation Stewardship, is the driving force behind Carbon Stewardship Solutions.

Care for patients beyond the OR

Anesthesia’s environmental footprint affects the communities where our patients live. Reducing it is an extension of the commitment to patient well-being.

Stewardship of natural resources

We are caretakers — not owners — of the land, air, and water. Good stewardship means making decisions today that protect resources for future generations.

Responsibility to future generations

What legacy are we leaving? The choices made in operating rooms today have consequences that extend far beyond the walls of any hospital.

“Of all the questions which can come before this nation, short of the actual preservation of its existence in a great war, there is none which compares in importance with the great central task of leaving this land even a better land for our descendants than it is for us.”

— Theodore Roosevelt
