Profile
Five decades at the intersection of orthopedic surgery, medical devices, information systems, and entrepreneurship. Converted the orthopedic surgery field from film-based to digital radiology on a national basis — inventing the echoeSYSTEM PACS, personally filing and obtaining FDA 510(k) clearance (K051745, 2005), and building Medstrat, Inc. into a national PACS platform that sold to Zimmer Biomet for $80M in 2023. Co-invented surgical instruments and neuromonitoring systems across Stryker and Johnson & Johnson tenure. Founded OPERhythm, LLC to develop entropy-minimized surgical workflow systems grounded in information theory and Ashby cybernetics. Currently building LiquidETH Co., a decentralized finance liquidity company, and advancing JointSpace.org, a nonprofit devoted to health data privacy and consumer rights. A lifelong parapetetic self-didact whose academic pursuits span physiology, information theory, cybernetics, causal inference, and the philosophy of knowledge.

~Late 1990s–2023
Medstrat, Inc. — Illinois
Co-Inventor, Principal & Regulatory Filer
Invented the echoeSYSTEM PACS — converting orthopedic surgery from film-based to digital radiology on a national basis. The first nationally networked archival and digital templating system for orthopedic practices. Personally authored and submitted FDA 510(k) K051745 (filed June 29, 2005; cleared July 14, 2005 — 15-day clearance, achieved without a regulatory consulting firm). Sold to Zimmer Biomet, October 2023. Sale price: $80,000,000.

Distributed Johnson & Johnson hip and knee products across Pennsylvania and Ohio. Pittsburgh Strip District headquarters.
~1985–1995
Stryker — Michigan, Texas, Pennsylvania
Distributor / Regional Manager
Distributor of hip and knee systems in Michigan, Ohio, and Texas. Constant operating room presence during joint implant reconstructions. Created feedback loops translating in-theater clinical learnings to corporate development engineering. Developed and refined customized instrumentation and instructions for surgical teams performing hip, knee, and spine reconstructions. Several instrument patents resulted.
~1975–1985
Zimmer & Kidder Peabody
Formative Roles
Orthopedic device and financial services roles in the formative career decade.
~1979–Early 1980s
The Upjohn Company — Michigan / Westchester, NY
Medical Representative & UMich Hospital Liaison
Began as medical representative in suburbs of southern Oakland County. Interned in a hospital in Westchester, NY. Became Upjohn's representative to the University of Michigan Hospitals.

Continuing Academic Pursuits
A parapetetic self-didact whose formal academic preparation in biological sciences and physiology opened into sustained independent study across a wide range of disciplines. Maintains a reference library of more than 1,000 journal articles, books, and conference papers. Current and recent areas of independent study include information theory (Shannon), cybernetics (Ashby), causal inference (Pearl), philosophy of knowledge (Deutsch, Popper), assembly theory (Walker, Cronin), and the mathematical laws of thought (Boole). Reaches out directly to researchers whose work bears on the problems at hand — including correspondence with the lead author of operator choice complexity studies at the University of Michigan confirming applicability of their assembly-line entropy model to surgical environments.
