alumni association

IT'S AUTOMATIC! Deerfield's Alumni Association is composed of every former student of the Academy, including those who left prior to graduation for any reason. Once you’ve attended Deerfield, you’ll always have a place here. There are no membership fees or dues. Deerfield’s alumni body is a vast and varied group that reaches around the world, with alums now living in over 25 countries. Deerfield alumni have ventured into almost every area of employment, and many are at the top of their respective fields. The nearly 12,500 members of the Alumni Association are a remarkable group and form an incredible network. Almost every one of us can say they have ‘run into’ other Deerfield alumni at some point in the recent past. We endeavor to create events and programs that will appeal to all ages as well as offering different services to our alumni. While we can’t promise to use every suggestion, we welcome your ideas and look forward to hearing from you.

Benefits of Membership

The Deerfield family consists of every current and former student, parent, and friend. As in any family, being a member confers a number of benefits, but also calls for fulfillment of certain responsibilities that contribute to the continuing strength of the family. Upon graduating from Deerfield, alumni enter a vast and diverse network that offers numerous and significant advantages. Benefits of alumni membership extend beyond these opportunities.

Features

Every member of the Deerfield family receives the following:

Alumni are also eligible for alumni awards, such as the Ashley Award, Heritage Award, and the Mimi Morsman Award.

Responsibilities

There are no membership fees or dues for members of the Deerfield family, but Deerfield does ask for assistance in a few areas. First of all, in order for Deerfield to have the most up-to-date records possible, we encourage members to keep us apprised of their current contact info. Alumni are also urged to direct all concerns and suggestions regarding Deerfield’s operations through the Executive Committee, the governing body of the Alumni Association. The committee acts as the voice of the alumni body, and works closely with the school administration. In order to keep tuition affordable and the quality of a Deerfield education at its highest, the Academy depends upon the continuing support of alumni and their families. This support can take the form of annual or capital gifts, or time spent volunteering on behalf of Deerfield.

Being a member of the Deerfield Alumni Association means you will always be a part of the Deerfield family. Come back for reunions or just for a visit, write often, and continue to be worthy of your heritage.

Visions and Initiative

Back in 1969 when the Alumni Association began, under the guidance of Alumni Secretary Robert Barrymore Crow, an Executive Committee was formed to serve as the governing body of the association and to perform a vital, positive, and meaningful role on behalf of Deerfield Academy and its alumni.

Today, thanks to our uniquely dedicated alumni and the tireless efforts of the Advancement Office, a growing number of initiatives are bearing fruit. Each year, the committee presents the Heritage Award, the Ashley Award, and the Mimi Morsman Award in recognition of outstanding achievement or service by alumni or members of the Deerfield staff.

Other current initiatives include: Pathways, where current seniors hear alumni present the “pathway” that they took to their career and offer anecdotes of how Deerfield impacted that path; Deerfield Days of Service, with alumni in regions around the country participating in designated volunteer public service activities such as environmental cleanup, food bank service, and the like; From Albany Road, a periodic e-newsletter which communicates news of events, activities, and other matters of interest to the alumni body; and the ongoing development of regional clubs both nationally and internationally. We welcome your suggestions for engaging our alumni with each other and with the school.

To find out more about any of the above initiatives, please contact the Advancement Office.

Awards

Deerfield alumni go on to live the values they encountered here. They strive to achieve greatness by embodying goodness. Their accomplishments deserved to be celebrated.

EXECUTIVE COMMITTEE
OF THE ALUMNI ASSOCIATION

Purpose

When the Deerfield Academy Alumni Association was officially established in 1969, an Executive Committee was formed to serve as the continuing governing body of the association. According to the written constitution of the Alumni Association, the purpose of the committee is "to communicate relevant information about Deerfield Academy to the members of the Association; to communicate to the Academy, when appropriate, the views of the Association and its members; to promote alumni engagement in support of the Academy; to strengthen bonds of friendship among alumni; and to encourage the development and facilitate the effective operation of regional alumni groups."

Membership

The present-day Executive Committee is composed of up to 30 members. Members are elected for a term of three years and are eligible for re-election to a second three-year term. The committee is led by the president, who serves a single three-year term and also sits on the Board of Trustees during their tenure.

Election

Candidates for election are suggested to the Nominating Committee by the staff of the Advancement Office and by current Executive Committee members. New members are nominated to fill existing vacancies by vote of the Executive Committee. The chief criteria for membership on the Executive Committee are a demonstrated interest in the welfare of the Academy as evidenced by prior volunteer service or other activities on behalf of the school, and a willingness to attend at least two of the three Executive Committee meetings each year (although it is unusual for members not to attend all meetings), with participation via conference call if unable to attend in person. Members are also chosen with the added goal that the Executive Committee should inclusively represent the alumni body as a whole.
