About EY-Parthenon

Parthenon-EY is a strategy consulting outfit with 900 members in 29 office locations worldwide. The firm advises c-suite, business, and organizational leaders across multiple sectors, including consumer, diversified industrial products, education, financial services, health care, life sciences, oil and gas, private equity and technology, media and telecom. Parthenon-EY's clients include Global 1000 corporations, as well as high-potential growth companies, private equity clients, health care and education clients, and nonprofit groups.

A powerful combination

In 2014, The Parthenon Group, founded in 1991 by two former Bain consultants-John Rutherford and William Achtmeyer- combined with big four member EY. The combination brings together Parthenon's experience -- strategy capabilities and experience with niche to traditional business models - and EY's global reach and implementation capabilities to deliver full-suite solutions to their clients. While the combined business is part of EY's Transaction Advisory Services, it operates under the Parthenon-EY brand and the leadership of Founder and Senior Managing Director Bill Achtmeyer.

Boutique firm culture, big firm capabilities

While Parthenon-EY may be able to access the power, global reach, and capabilities of one of the world's corporate giants these days, it still retains its trademark boutique culture and focus. The organization's leadership has remained intact, along with functions critical to retaining culture--specifically recruiting, staffing, training and professional development. Given that, it's no surprise that consultants at the firm continue to highlight cultural factors such as a collegial atmosphere, entrepreneurial environment and transparent management.

Helping by example

Entwined in Parthenon-EY's DNA is the concept of giving back--something that starts at the top with Parthenon Founder Bill Achtmeyer. In addition to managing the Parthenon-EY organization, Achtmeyer is involved in multiple community organizations. His roles include serving as the Chairman and Board of Trustees of the Boston Symphony Orchestra, Overseer at the Museum of Fine Arts, Governor for the Handel and Haydn Society, Chairman of Tenacity and Former Chairman of the Massachusetts Society for the Prevention of Cruelty to Children. Achtmeyer also leads by example through frequent participation in the numerous charitable events, fundraising competitions and days of service in which all of the Parthenon-EY offices get involved. It is common among the firm's members to join efforts in a multitude of various charitable activities such as athletic fundraising events, packing school supplies for children in need, career mentorship for high school students, and holiday toy drives. The opportunities to give back are amplified through the combination with EY and EY's firm-wide commitment to building a better working world.
