Complementary skills and experience…
The two principals behind Amos + Advisors, Ann Marie O'Shea and Marcus Diggle, have very different backgrounds and skill sets. Ann Marie has built, operated, and exited multiple healthcare-related businesses. She has an MBA and is a Ph.D. candidate. Ann Marie’s deep and proven expertise in all aspects of financial modeling and business operations underpins all Amos business plans. On the other hand, Marcus has a creative background in publishing and sponsorship sales. He led a successful management buyout of New York-based publishing company Profile pursuit to form HealthSpring Communications. During this time, Marcus honed his ability to present complex ideas in a consumer-friendly way -- a handy skill in his current role. He has a rare ability to understand and articulate value propositions quickly, and his publishing experience helps Amos craft beautiful and resonant presentations and decks.
