Daniel Villiers, PhD

Dan Villiers completed his PhD in Counseling Psychology at Northeastern University in 2009. He also earned an MEd. in School and Applied Child Psychology from Kent State University and an MA in Cognitive Science from Dartmouth College. His academic journey began with a BA in Psychology, with a minor in Classics, from Kenyon College.

Originally from a small village in the Cotswolds, England, Dr. Villiers has lived in the US since attending The Thacher School in Ojai, California. His personal struggle with severe anxiety during high school sparked a deep commitment to developing innovative methods and programs to address the emerging epidemic of youth anxiety in the early 2000s. This dedication led him to co-found Mountain Valley Treatment Center in 2011 and the Anxiety Institute in 2016, both of which have become industry leaders in the residential and outpatient treatment of anxiety disorders, respectively. Over his 21-year career as a scholar-practitioner, Dr. Villiers has developed subspecialties in family-based exposure therapy for pervasive school avoidance and refusal, exposure/response prevention (E/RP) for treating OCD in both neurodiverse and neurotypical teens, and exploring the roles of perfectionism, avoidance, and self-sabotage in anxiety and mood disorders.

Dr. Villiers’s early career was profoundly influenced by his experience at Mountain Valley, where he witnessed the value of intensive treatment. This experience inspired him to create the first in-home intervention model for anxiety and OCD spectrum disorders. His return after eight years, now serving as an admissions and outreach consultant, marks a full-circle moment in his professional journey.

Dr. Villiers is based in South Carolina with his wife, Kate, an equestrian professional, and their two daughters, Bryn and Zara. He enjoys racquet sports, fishing, golf, and playing guitar and piano. Dan also enjoys vacationing in Naples, Florida, and visiting family in England, France, and Australia.

Cecelia Tarr, MSW, LICSW

Cece completed her Bachelor of Arts in Psychology and Exercise & Sport Science at Smith College and earned her Master of Social Work from the University of New Hampshire. Before graduate school, she supported children and families through community mental health work in their homes and neighborhoods. Following graduate school, Cece worked in an outpatient private practice, providing therapy to individuals of all ages with a focus on eating disorders and OCD.

In addition to her clinical training, Cece has a strong background in coaching. Growing up as a Vermont-based gymnast, she spent summers coaching gymnastics before transitioning to springboard diving in college. She later coached diving for eight seasons at UNH, with many top finishes. Cece believes her coaching experience continues to inform her clinical work, as therapy—like sports—often involves showing up with courage and a willingness to “do it scared.”

Cece is excited to return to the Upper Valley after several years in Portsmouth, NH. Outside of work, she enjoys skiing, mountain biking, reading, and spending time in nature.

Carl Lovejoy

Many know Carl as one of Mountain Valley’s co-founders and foremost ambassadors. From our founding in 2011 until 2023, Carl was omnipresent in Pike and Plainfield, making deep connections with both residents and their families.

In his current role as Mountain Valley’s Director of Development & Alumni Relations, Carl is focused on caring for our alumni network and ensuring a bright future for Mountain Valley—one in which we grow, evolve, and continue to serve our mission in bigger and better ways. Carl is the primary liaison for members of the Mountain Valley Alumni Association and is focusing his development efforts on enhancing our scholarship funds so that we can offer therapeutic services to adolescents who, without such support, would not be able to benefit from all that Mountain Valley has to offer.

Prior to his work at Mountain Valley, Carl enjoyed a 30-year career in boarding schools—teaching and coaching, then working in admissions and development at St. Paul’s, Tabor Academy, Cardigan Mountain School, and Kimball Union Academy. In 2010, he was asked if he might like to join the founding team of what was to become Mountain Valley Treatment Center. He said “yes,” and the rest is history.
