Peter D. Yeomans, 58, of Philadelphia, innovative clinical psychologist at the Corporal Michael J. Crescenz Department of Veterans Affairs Medical Center, founder of Cold Mountain Counseling LLC, worldwide mountaineer and backcountry adventurer, teacher, author, mentor, Quaker, and volunteer, died Friday, Aug. 28, of cardiac arrhythmia at the VA Medical Center in University City.
Dr. Yeomans was an expert in trauma, substance use disorder, moral injury, and spiritually integrated healthcare. He joined the Philadelphia VA Medical Center as a staff psychologist in 2009 and became director of its innovative PTSD outpatient team program in 2019.
He opened his own psychology practice, Cold Mountain Counseling, in 2021 and advised thousands of veterans, fellow backcountry adventurers, and other clients in need across the country. “He was instrumental in the healing process for so many veterans that it is hard to fathom the reach of his influence,” a VA colleague said in a tribute.
R. Tyson Smith, a friend and colleague, said several veterans told him: “Peter Yeomans saved my life.”
At the VA center, in addition to physical and mental ailments, Dr. Yeomans and others innovated a treatment for what are called “moral injuries” from military service. They connected therapists with VA chaplains to link emotional healing with faith rituals, and veterans in the program spoke appreciatively about shifting the guilt and shame of moral failures during war from soldiers in general to society at large.
“These are stories to hear and also for the public to wrestle with,” Dr. Yeomans told The Inquirer in 2019. His wife, Kate O’Shea, said: “He was the most responsible person you could imagine, and he felt he had a responsibility to humanity.”
Outside the medical center, Dr. Yeomans spent weeks at a time hiking, backpacking, packrafting, skiing, rock climbing, and mountain biking around the world. He reached summits in Alaska and Argentina, had to be rescued from a deep crevasse, and worked as a program supervisor and senior field instructor in the 1990s for the National Outdoor Leadership School in Alaska, Wyoming, Arizona, and Utah.
Later, he cofounded the local Wilderness Outdoor Leadership Force for teens in Kensington. Talia Young, a longtime WOLF member, called him “genuine and earnest … and joyful with kids.”
Longtime colleague Rob Riman said he was a “consummate adventure partner and wildly inspired guide.” On his website, coldmountaincounseling.com, Dr. Yeomans said: “Many of the fondest memories of my life are from adventures in the mountains.”
He earned a bachelor’s degree in psychology from Harvard University in 1991 and came to Philadelphia from Wyoming in 1997 to be with O’Shea. He earned a master’s degree in psychology from Lesley University in Massachusetts in 2001 and a doctorate in clinical psychology from Drexel University in 2008.
Dr. Yeomans traveled to New Zealand, Rwanda, Burundi, and elsewhere to train other counselors. He worked in state correctional institutions in Philadelphia and Chester, and earlier for the American Red Cross in Germany.
He wrote papers and articles about his research, and his book, Reclaiming Integrity After Moral Injury From War, is to be published in 2027. He organized workshops and panels, and was active with the Nationalities Services Center, the Association for Behavioral and Cognitive Therapies, and other groups.
He taught classes on moral injuries at Germantown Friends School, the University of Pennsylvania, and elsewhere. Longtime friend William Anninger said: “He was particularly good at creating emotional sharing among men.”
Friend Lila Berman said: “He exuded warmth and care for the people around him, and for the natural environment.”
Peter Douglass Yeomans was born Aug. 27, 1968, in Berkeley, Calif. The family moved to Massachusetts when he started high school, and he graduated from Concord Academy in 1986.
He met Kate O’Shea at an environmental ethics course in Utah in 1996, and they married in 2002 and lived in Germantown. He made her tea in the mornings and left love notes behind when he left the house first. They reared a daughter, Ada, and sons Josiah and Levi, and they all went on memorable adventures in Wissahickon Valley Park, across the country, and around the world.
“They complemented each other perfectly,” their daughter said. “He taught us how to read a map, find a campsite, and most importantly bake cinnamon rolls in the backcountry.”
Dr. Yeomans was a member of the Bicycle Coalition of Greater Philadelphia, and he rode his bike often from home in Germantown to work in University City. He went to Germantown Friends Meeting, played guitar, sang, and acted in theatrical shows in high school and later with community groups and his family.
He was inclusive and encouraging, his brother, Ben, said, “drawing out capacities in me I wasn’t yet trusting.” His parents, Anne and Tom, said: “It has been a great privilege to have been Peter’s parents.”
His mother-in-law, Margaret O’Shea, praised his “compassion, selflessness, nobility, and grace,” and his father-in-law, Dan O’Shea, said: “When our daughter met Peter she described him as ‘Mr. Perfect.’ Little did we know how perfect.”
Kate O’Shea said: “Because of Peter, our world is a kinder, more generous, and more loving place.”
In addition to his wife, children, parents, brother, and in-laws, Dr. Yeomans is survived by other relatives.
A memorial service is to be held at 2 p.m. Saturday, Oct. 3, at Germantown Friends Meeting, 47 W. Coulter St., Philadelphia, Pa. 19144.
