Some problems do not fit inside a framework.
I work with founders, executives, and organizations at moments of consequence — transitions, acquisitions, growth that has outpaced the infrastructure holding it together, complexity that has stopped responding to conventional management.
The work is bespoke. Engagements vary considerably in scope and duration. Industries are incidental.
Engagements are confidential. The following reflects the nature and scale of past work.
Built the operational and financial architecture that carried a venture from founding through a $28 million acquisition.
Conceived and scaled a national conference into the largest gathering of its kind in the United States — 2,500 delegates, sustained annually over more than a decade.
Managed a $10 million annual portfolio across fifty-plus concurrent engagements with a team of fifteen, through a period of significant organizational transition.
Advised on post-acquisition integration, vendor restructuring, and the transformation of a founder-led organization into an institutional one.
Jeffrey Tarnoff has spent two decades building, operating, and advising organizations that required something more than conventional management.
He co-founded two ventures — a medical education firm acquired for $28 million and a national conference that became the dominant event in its field. He has since served in senior executive roles at organizations navigating acquisition, rapid growth, and structural change.
He does not take on many clients.
Engagements are considered on a limited basis, and most begin through introduction.
If you have been referred, or if the circumstances are compelling enough to warrant an exception, write directly.
