Meet Our Treatment Team

Heather Kirby, LCSW, CSAC

Heather Kirby is a Licensed Clinical Social Worker (LCSW), a Certified Substance Abuse Counselor (CSAC) and holds a Master's degree in Special Education. Heather has worked with teens, tweens, young adults and their families for over 20 years in a variety of treatment and education settings.

Heather uses a direct, compassionate and creative approach to connect with clients that others have found difficult to reach. She draws upon alternative interventions (equine therapy, recreation, sand tray, music, writing, art, and movies) to effect life changes in those resistant to more traditional forms of therapy.

Heather brings to Project Horse a lifetime of passion for horses and experiential learning. In college she rode with the William and Mary riding team. After college, she spent three years as a dedicated volunteer with the National Center for Therapeutic Riding. In 2010, she was among the first class to graduate from Melisa Pearce's certification program in the Equine Gestalt Coaching Method. In 2012, Heather was recruited to develop the equine therapy program at Child Help East, a residential treatment program for abused and neglected children. While there, she was quoted on CNN as saying that 4-legged therapists are better than those with two legs.

In 2013, Heather published "Wild at Heart: Adolescents, Horses and Other Kindred Spirits" in which she shares her unique perspective that adolescents and horses are very much alike and outlines her innovative approach to connecting with adolescents by using strategies known to be effective with horses. In 2014, she completed advanced training in Trauma-Focused Equine Assisted Psychotherapy under the guidance of Tim and Bettina Jobes. Heather is a life-long learner and continues to add to her arsenal of clinical tools, currently working toward certification in EMDR. She swears, however, that animals and her courageous clients have been her greatest teachers.

Darcy Woessner, CES

Project Horse Empowerment Center
Founder & Executive Director

Darcy grew up riding and competing horses, then left for other pursuits as a young adult. Darcy holds an MBA in International Business and has worked for large multinationals like Michelin Tire Corporation and Colgate-Palmolive. She has also worked as a marketing and development consultant in both the for-profit and nonprofit sectors.

During a period of professional soul-searching, Darcy returned to her passion for horses. It was at this time that Darcy came across the horse, now known as Reeses, who could no longer be ridden due to an untreated injury and found her in desperate need of care. Rescuing and rehabilitating Reeses strengthened Darcy's long-time belief that horses are powerful healers, and together Reeses and Darcy founded Project Horse in 2008.

In addition to running the organization, Darcy is very involved with client services. She is an EAGALA-certified Equine Specialist and co-facilitates many individual and group programs. Darcy is currently in the certification process as an Equine Specialist in Trauma Focused-Equine Assisted Psychotherapy. Darcy also leads the Mobile Minis community outreach programs off-site. Darcy and Fiona Fudge, one of the Mobile Minis™ team, have appeared on NBC News Channel 4 and ABC/News Channel 8's The Pet Show with Dr. Katy.

Maria Kimble, CES

DIRECTOR, Equine Wellness

Maria left a successful management career in telecommunications to immerse herself in her lifelong passion of helping animals, with a specific focus on horses.  She has volunteered with horse rescues, dog rescues, avian rescues, and more. 

Maria served on the Board of Directors of an organization that rescued wild horses and burros from horrible circumstances, rehabilitated them and then secured lifetime sanctuary for each.   She is a citizen lobbyist, making many trips to Richmond and Capitol Hill to advocate for equine welfare.  Maria’s dedication to equine welfare led to her starting her own non-profit, an organization that advocates for and provides a safety net for at-risk equine in Virginia.

Since 2010, Maria has been a full time volunteer with Project Horse Empowerment Center.  While her intent was to serve the horses in her care, Maria soon found herself drawn to the therapeutic work and wanted to help humans through the power of the equine spirit.   Maria is a Certified Equine Specialist under the EAGALA model, co-facilitating individual and group sessions at Project Horse. She also co-facilitates Mobile Minis visits in the community and is certified in Mental Health First Aid.   Maria is pursuing an Equine Specialist certification in Trauma Focused-Equine Assisted Psychotherapy.

Maria is a Certified Equine Sports Massage Therapist and is trained in the application of kinesiology tape for equine.  She regularly donates her services to equine rescues and sanctuaries, and also has several equine athletes as clients.  The horses at Project Horse also enjoy massages on a regular basis.


Martha Briggs, CES

Martha has been with Project Horse since 2014, taking care of the horses as well as participating in sessions as a Certified Equine Specialist. She grew up in Vienna, Virginia and has been involved with horses since the age of 8. The youngest of nine children, she learned at an early age how to be part of a herd.

When Martha wasn't with her family, her favorite place to be was at the barn with the horses, where she found solace and peace. As she became an adult, her life steered her away from the barn, and into becoming a mother and raising her children in a loving, supportive household.

After working in the legal field for 18 years, she decided to return to her true passion of working with horses and exploring their relationship with people. This experience has resulted in her EAGALA certification as a Certified Equine Specialist. She and her family currently reside in Purcellville, Virginia.

Emily Williams, MA

Emily started interning with Project Horse in 2016 after completing her master's degree in psychology. Her love of horses began as a young child with a pony ride, and as a teenager she could often be found working at the barn to earn extra lessons. These days, on her days off she can often be found hiking or practicing agility with her rescue cocker spaniel.

During the week she currently works part-time with individuals with severe and persistent mental illness at a psychiatric assisted living facility. The rest of the week she enjoys working on a variety of projects at Project Horse.
