Our team
The principals

Founder and Chief Executive Officer
Erich Walsh
Erich Walsh founded Fractional Aviation Advisors to bring independent, analytically rigorous guidance to private aviation clients, a discipline he developed over nearly a decade advising some of the most sophisticated fractional ownership clients in the country.
From 2016 to 2024, Erich served as Senior Vice President of Sales at NetJets, the world's largest private jet operator and a subsidiary of Berkshire Hathaway. At NetJets, he advised private clients, family offices and corporate teams on program selection and renewals. His tenure at NetJets also included direct responsibility for a significant portfolio of client accounts, an experience that informs the firm's account management practice as directly as it informs its acquisition advisory.
Prior to NetJets, Erich spent over two decades in finance, developing the analytical framework and structured evaluation discipline that now underpins every cost model, proposal analysis, and contract review Fractional Aviation Advisors produces. That background, applied to the operational complexity of private aviation programs, is the combination that defines the firm's advisory approach.
Outside work, Erich enjoys cycling, reading and time with his family.

Executive Aviation Advisor
Steve Eiseman
Steve Eiseman co-founded the fractional jet ownership model alongside Richard Santulli in 1986, serving as NetJets' first-ever sales executive. What he and Santulli built, originally as Executive Jet Aviation, was acquired by Warren Buffett's Berkshire Hathaway in 1998 and grew into the dominant force in global private aviation. The fractional ownership structure that defines the industry today is, in meaningful part, the product of the model Steve helped create and spent his career developing.
Over more than three decades at NetJets, Steve worked with private aviation clients across the full spectrum of program decisions and the full range of client profiles: C-suite executives, family offices, major institutions, and individuals at the highest levels of business and public life. That depth of direct client experience, accumulated over the entire history of the fractional ownership industry, is the foundation of the advisory perspective he brings to Fractional Aviation Advisors.
Steve has spent his career guided by the principles of safety, quality, and long-term client relationships, a set of priorities that translate directly into the firm's approach to every advisory engagement.

Senior Advisor, Strategy and Finance
John Paul Nicolaides
John Paul Nicolaides brings more than three decades in senior finance and mortgage leadership to the firm's analysis of long-term aviation costs and commitments.
He helps translate complex analysis into clear recommendations for principals, family offices and corporate teams. He is fluent in French, Spanish, and English, and serves in advisory and governance roles across several civic and community organizations.
Our approach
How we advise clients
- Independent of any operator
- We are not affiliated with any operator, and we take no operator commissions or referral fees. Our recommendations are aligned solely to your situation.
- Scope and fee agreed before any engagement
- Our fees are custom for each project and depend on its scope. We agree the scope and fee with you before the engagement begins.
- Analysis built on your own numbers
- Utilization modeling, cost benchmarking and scenario forecasting are built from your own trips and documents, not industry averages or a provider's projections.
- Advisory, alongside your other advisors
- We advise on the aviation options and the commercial terms. Legal and tax questions belong with your own counsel and tax advisor, and we work alongside them.
Our independent aviation advice takes two forms: acquisition guidance before a commitment is made, and account management once a program is in place. Every engagement begins with a confidential conversation, and there is no obligation to engage us.
