Our Leadership

Our Team

Samantha R. Guild, J.D.

Samantha (Sam) Guild left a successful career as a litigation attorney in 2008 to become the Director of Education, Public Policy, and Advocacy for AIM at Melanoma, the foundation her mother, Valerie Guild, founded after Charlie Guild—Sam Guild’s sister and Valerie Guild’s daughter—died of melanoma in 2003.

For Sam, AIM at Melanoma is a labor of love, and the family has one over-arching goal: to end melanoma. AIM’s success is a testament to their hard work and the enduring spirit of hope and helping others that Charlie left behind.

As President of AIM at Melanoma, Sam works closely with grantors and the AIM team on future goals for the foundation. A large part of her role at AIM includes the oversight of the creation of resources for patients, caregivers, and health care providers—resources such as patient treatment decision-making tools, AIM’s melanoma oncology nursing website, IO Essentials website, and the AIM at Skin Cancer website.

In her public policy work, Sam supports state legislators in introducing and passing indoor tanning device legislation. She led the effort in California that resulted in 2011 in the passage of the first bill to ban minors under 18 from using tanning devices. She is a public speaker and prolific writer on the impact of indoor tanning legislation, risks, and restrictions, with an emphasis on tanning’s effect on minors. In addition to her public policy work on indoor tanning legislation, she oversees AIM’s effort to support oral parity and step therapy legislation on the
state and federal levels.

In her advocacy role at AIM, Sam sits on a variety of governmental and non-profit working groups and committees where she advocates for the melanoma community, including NCCN, SWOG, and ECOG, and the ASCO’s systemic therapy melanoma working group. She is frequently asked by researchers and industry to share the patient perspective on topics of importance to their research.

Sam received a bachelor’s degree from Clark University in Worcester, Mass., where she studied American government and women’s issues. She earned her law degree from the University of the Pacific, McGeorge School of Law, in Sacramento, Calif. She is a member of the State Bar of California and a native of New York.

Valerie P. Guild, M.S., M.B.A.
1947- 2020

When Valerie Guild lost her beloved 26-year-old daughter Charlie to melanoma in 2003, she vowed to help find the cure for the disease and founded AIM at Melanoma as the vehicle to do so.  Four years later, Guild was joined by her daughter, Sam Guild, who gave up her career as a litigation attorney to work with AIM and is now AIM’s President.

AIM at Melanoma has grown to be a global foundation that, in Val’s words, tackles the “hard stuff”—projects that are deemed critical for progressing research but also considered too difficult to accomplish.

Val Guild died May 21, 2020. AIM’s small but mighty (as she called us) staff will continue her work in her memory, with absolute resolve, as she had, to help find the cure for melanoma in our lifetime.

Alicia Walker Rowell
Vice President

Alicia Walker Rowell is Vice President and principal fundraiser at AIM at Melanoma.

Rowell has a personal stake in the foundation’s mission: Her husband is a Stage III melanoma survivor.

Like many non-profits, AIM relies on the charitable donations of generous supporters to fulfill its mission, and Rowell was hired to build a philanthropic infrastructure for AIM while simultaneously growing the number of donations the organization receives.

Directing all aspects of AIM’s philanthropy, from annual giving to major gifts, Rowell worked closely with Val Guild, AIM’s Founder, and now with Samantha Guild, AIM’s President, on AIM’s global research initiatives, where the majority of AIM’s budget goes, and on the overall direction of the foundation. She also works closely with Michelle Bessett, AIM’s National Director of Walks & Events, to increase the visibility of and grow AIM’s fundraising walks and events. She is often called upon to write and speak on behalf of AIM to raise both funds and awareness.

Rowell enjoys the multidimensional aspects of her job and the many different roles she has within the foundation to support AIM’s mission.

Rowell came to AIM having worked most recently in development and administrative roles at the University of California, Berkeley—including directing the capital campaigns for Berkeley’s athletic department, where she raised over $25M for the campus—and writing, editing, and teaching roles prior to that.

She is a graduate of the University of California, Berkeley, earning a degree in English and History, and a fourth-generation Californian.

In her role at AIM, Bessett provides year-round support for about 20 local walks across the country, and she hopes that number will keep growing.

Before coming to AIM, Bessett served as a team captain for a local Heart Walk, then she was hired on as a walk director with the American Heart Association – a position she held for five years. She also had development and walk roles with the March of Dimes and the United Way.

Although she doesn’t have a personal connection to melanoma, she is similarly honored to work for an organization that provides so much to melanoma patients, survivors, families, and caregivers.
