Thom Gunderson is a medical technology analyst and public company director whose career has run through the companies, the capital markets and the boardrooms of the medical device industry.
From 1992 through 2016 he was a Managing Director and senior research analyst at Piper Jaffray, covering medical technology companies in the public markets. His work focused on the questions that determine how sophisticated investors assess a business: product differentiation, clinical evidence, competitive position, management execution, growth durability and valuation.
Before Piper Jaffray he spent thirteen years at American Medical Systems, from 1979 to 1992, including as Project Director, remaining through the company’s acquisition by Pfizer in 1983. He came to the capital markets from inside the industry rather than from outside it.
His board service and biography are matters of public record in proxy statements filed with the U.S. Securities and Exchange Commission. Windsor Drake links to those filings directly rather than summarizing them, for the reason set out below.
Windsor Drake represents founders and owners in the sale of their companies. Thom Gunderson advises the mandates where the company being sold is a medical device, diagnostics or healthcare technology business, and where the outcome turns on how buyers read the clinical and competitive evidence.
He pressure-tests the equity story before a buyer does. He helps distinguish durable product and clinical advantages from features buyers will discount, assesses strategic buyer fit, refines valuation and competitive positioning, and prepares management for the questions that surface in buyer review and diligence.
His perspective translates the underlying quality of a medical technology business into a transaction thesis that corporate development teams and boards can underwrite.
Four vantage points matter in a medical technology sale. Thom Gunderson has worked from all four.
Medical technology buyers pay for evidence, not claims. Twenty-four years of covering the sector taught him which clinical data moves an acquirer’s model, which regulatory positions hold up under scrutiny, and where a claimed advantage is really a feature the market will compete away. Sellers who assemble that evidence before the process keep control of the narrative. Sellers who assemble it during diligence lose price.
He spent more than two decades analyzing the acquirers themselves: how the major strategics build their corporate development pipelines, what gaps they are trying to fill, and how they justify a premium internally. That vantage point shapes buyer prioritization, which is where a process is won before it begins.
Private sellers are ultimately priced against public comparables, because that is how a strategic acquirer’s board frames the decision. Having set and defended those frameworks in the public markets, he knows which metrics carry the argument and which are ignored.
He sits on the boards that approve transactions. He knows the questions a public company board asks before it authorizes an acquisition, because he is one of the people asking them.
Medical technology buyers do not pay for claims. They pay for evidence: clinical, commercial and competitive. The work is assembling that evidence before the first buyer conversation, not during diligence.

Windsor Drake links to the record rather than paraphrasing it. Credentials that cannot be checked are not credentials, and a firm asking to represent the largest transaction of an owner’s life should expect to be verified rather than believed. His board service, committee roles and biography are set out under the name Thomas J. Gunderson in Merit Medical Systems’ proxy statement and TransMedics Group’s proxy statement, both filed with the U.S. Securities and Exchange Commission in 2026.
Owners of medical technology companies contact Windsor Drake at very different points: holding an unsolicited offer, a year out from a process, or simply wanting to understand what a buyer would find. Thom Gunderson advises those conversations directly.
