About Passports

Our story.
And the story of an industry.

Passports Educational Travel didn't just enter the educational-travel business in 1992 — it spun out of it. The lineage runs back to the early 1960s, to a Clark University philosophy professor who packed up a group of his students and flew them to Europe one summer.

  • Early 1960s — a concept is born at Clark University
  • 1965 — American Leadership Study Groups (ALSG)
  • 1992 — the Passports era begins in Spencer, MA
  • Today — family-owned, run by the founder's son
  • How the rest of the industry traces back to ALSG
We weren't trying to start an industry. We just kept booking flights for kids who wanted to see Europe — and one day there were fifty people working night and day at the Worcester Airport.

From a Clark University classroom
to a Worcester storefront.

Four eras. One continuous family-run business. Here's the whole arc, in order.

  1. Dr. Gil Markle, philosophy professor at Clark University
    Early 1960s · Worcester, MA

    A philosophy professor takes his class to Europe.

    Dr. Gil Markle's academic background was unusually broad before he ever stepped into a classroom. Undergrad in physics at Rensselaer Polytechnic Institute. A Doctorat d'Université in philosophy at the Sorbonne, in Paris, on a Fulbright Scholarship. A PhD in the Philosophy of Science from Yale. Earlier, service at Camp Century with the U.S. Army Corps of Engineers — the experimental nuclear-powered research base under the Greenland ice sheet.

    By the early 1960s he was teaching at Clark University in Worcester, Massachusetts, already legendary on campus for the way he taught — interactive, unscripted, deliberately uncomfortable.

    One summer he loaded a group of his students onto a flight to Europe. The trip was so well-received that he ran it again the next year, and the next, eventually organizing more than twenty groups a year. The route — England, France, Italy — became what's now Passports' Grand Tour. The phrase “outbound educational travel” didn't really exist yet in America. Gil was, in real terms, inventing the category.

    The seed of an industry
  2. American Leadership Study Groups headquarters era, 1965–1988
    1965–1988 · Worcester Airport

    American Leadership Study Groups (ALSG).

    In 1965, Gil formalized what he'd been doing on the side. American Leadership Study Groups—ALSG—was the first outbound student travel company of its kind in the United States, headquartered at the Worcester Airport with a staff of more than fifty people working night and day.

    ALSG built the playbook. Detailed pre-departure curriculum binders. Tour Director training programs. Standing relationships with hoteliers and restaurateurs in every European capital. The infrastructure that the rest of the industry would borrow from for the next forty years started in this building.

    Over twenty-three years, ALSG sent thousands of American students overseas. Many of those alumni — staff and travelers — went on to start the companies whose names you know today.

    1992 · Spencer, MA

    Passports Educational Travel begins.

    After the ALSG chapter closed, Gil started Passports Educational Travel. Many of the early Passports staff were former ALSG hands—people with twenty or thirty years of educational-travel experience already on their résumés when the company opened its doors.

    Why Spencer, Massachusetts? Because Gil also owned a world-class recording studio in nearby North Brookfield that had hosted the Rolling Stones, Stevie Wonder, and Cat Stevens. He wanted his new company close to the studio he'd built. Worcester County is where Passports has been ever since.

    The legacy continues, in the same county where it started.

    Passports is now led by Gil's son, David Markle, with longtime Vice President Dale Davies at his side. The office moved from Spencer to downtown Worcester, the company has weathered SARS, 2008, COVID, and the airline meltdowns of 2022 — and the family has stayed put.

    Same Tour Director ranks. Same direct line to the founder's son. Same answering of the phone, in Worcester, when you call.

    Family-owned. Still.

Side note worth knowing

Why Passports is in Worcester
and not in New York or Boston.

When Gil started Passports in 1992, he could have set up anywhere. He picked Spencer, Massachusetts because it was fifteen minutes from his other thing: Long View Farm Studios in North Brookfield, a converted dairy barn that had become one of the more storied recording studios in the country.

A short selection of who passed through that barn while Gil was running it:

  • The Rolling Stones1981 tour rehearsals
  • Stevie Wonderrecorded sessions
  • Cat Stevensrecorded sessions
  • Aerosmithrecorded sessions
  • The J. Geils Bandrecorded sessions
  • Bob Marley & the Wailersrecorded sessions
A footnote

Most of today's big educational-travel
names trace back to one Worcester building.

ALSG was the first of its kind in America. By the time it wound down, twenty-three years of staff had cycled through it. Several of those alumni went on to start, run, or significantly shape other companies in the industry.

NETC → WorldStrides
National Educational Travel Council. Started by alumni of the ALSG sales floor.
EF Tours
Educational-tour vertical built up partly by ALSG hands who went into international expansion.

We're proud of the alumni network. We just happen to be the one that's still in the family.

The legacy continues

David Markle, second generation.

David MarklePresident, Passports Educational Travel

A computer scientist running an educational-travel company.

David holds a master's in computer science. He runs the company in his father's spirit — same Tour Directors, same Worcester office, same answer-the-phone ethos — while also bringing it firmly into the present. The PassportsGo app ships from a small in-house engineering team. The website you're on right now is a from-scratch rebuild on modern infrastructure.

Outside the office, David is the father of four, a lifelong learner, an aspiring musician, an AI enthusiast, and an unrepentant kebab-seeking traveler — the kind who'll fly overseas every year to meet up with groups while they're on tour and turn dinner into a small expedition for the best one in town. If you're booked with us this season, there's a real chance the person who helped you plan your trip will introduce you to David in person somewhere between London and Rome.
