01
Surgery begins before the incision.
The weeks before an operation and the weeks after it are part of surgery, and they deserve the same care.
About PERIOME
PERIOME is the Perioperative Health Company.
PERIOME is building the connected infrastructure for Perioperative Health across the full perioperative episode, from the moment surgery is planned through meaningful recovery. It was founded by two board-certified anesthesiologists.
Founders
Built from inside perioperative care.
Chad Greene and Daniel Hansen are board-certified anesthesiologists. They started PERIOME after years of caring for patients on the morning of surgery, and seeing what the weeks before it could have changed.
“We kept meeting patients on the morning of surgery who could have been prepared weeks earlier.”

Why we started
Medicine made the operation extraordinary. The weeks around it were still pieced together by the patient.
Chad Greene and Daniel Hansen identified the same gap across thousands of cases: patients arrived cleared but not ready, and recovery at home went largely unseen. They founded PERIOME to build the infrastructure around the full perioperative episode.
The pieces of good perioperative care already existed. What the patient lacked was a system that connected them.
What we believe
Three principles behind the company.
02
Connect what exists.
Surgeons, anesthesiologists, primary care and nursing already do essential work. PERIOME's job is to connect it around the patient, not replace it.
03
Evidence before claims.
We build what is useful now, measure honestly, and let the evidence decide what comes next.
The company
One discipline. One connected system.
The company is built in layers, and each one is described for what it is today.
We are building for the long term, while the field is still being defined, and saying plainly what exists today.
- Perioperative HealthThe discipline: the full surgical journey, from the decision for surgery through meaningful recovery.
- PERIOME OSThe connected infrastructure, being built to link the patient, the care team and the institution across the episode.
- Perioperative IntelligenceThe longitudinal learning layer, built through use and study.
- Morton™ and the PERIOME ProtocolThe early patient-facing components. Morton is in pilot; the Protocol launches with its first production run.
Beyond the company
A field is bigger than the company that names it.
Two anesthesiologists started PERIOME. Defining a discipline takes far more people than that, which is why PERIOME convenes the Perioperative Health Council.
It brings clinicians, researchers, health system leaders and operators into defining what Perioperative Health measures, what evidence it holds itself to, and what it may claim.
About the CouncilThe standard
No patient enters surgery unknown.
