In this episode of TheMilVet Podcast, host Beau Higgins sits down with Mike Gaffney, Naval Academy graduate, former nuclear-trained submarine officer, and now CEO of Cellphire Therapeutics, Inc., to unpack a career that spans undersea operations, top-tier consulting, private equity, and biotech leadership.
Mike shares how growing up around his father’s Naval Academy classmates and mentors, including a future vice admiral, shaped his decision to attend the Academy, not for prestige, but for values, character, and leadership. An unlikely nuclear submariner who majored in English and later earned a graduate degree in politics, he explains how the process of elimination, the end of the Cold War, and a few hard realities (like getting seasick and wearing glasses) pushed him beneath the surface and into the Navy’s nuclear community.
Mike then walks through his pivot from consulting into the investment world with Allied Capital, where he ultimately became the firm’s de facto healthcare lead. He breaks down how the private equity landscape has transformed since the late ’90s, from a smaller, less crowded field to today’s hyper-competitive market where deal flow, specialization, and relationships are everything and why that shift pushed him toward building companies rather than just backing them.
Throughout the conversation, Mike offers practical insight on:
- Leveraging your network the right way; focusing on adding value, reciprocity, and long-term relationships rather than transactional asks
- Translating military leadership into commercial settings by obsessing over team quality, clarity of purpose, and execution discipline
- Surviving “getting punched in the face” in business through resilience, problem solving, and resourcefulness forged in uniform
- Understanding how modern private equity and growth capital really work; why deal flow, specialization, and operating value creation matter more than ever
- Stepping into a new leadership role with humility, curiosity, and a deliberate approach to listening before changing things
- Shaping culture intentionally so strategy doesn’t just live on a slide, but shows up in daily behaviors and decisions
For veterans interested in private equity, venture capital, or executive roles in high-growth companies, Mike offers grounded advice: this is a brutally competitive space where many people want the same jobs, but trusted introductions, demonstrated grit, and a reputation for solving hard problems can differentiate you. He emphasizes that trust and likeability aren’t built in one conversation or a single coffee, they compound over time through consistent behavior, follow-through, and showing up for others.
