Clinical Staff

Rachel H. Graham

President and Co-founder, MBA

Rachel, as President and Co-founder of Healing Springs Ranch, brings her own personal journey as a family member of a loved one who struggled with unresolved trauma, mental health issues, and addictions. She observed firsthand some of the poor treatment programmings that failed to identify the core issues both with the individual struggling as well as the family unit. As a result, she chose to put her energy and heart into working with a team of talented founding partners and staff to create Healing Springs Ranch.

Her personal mission is to affect change in addiction treatment by treating all aspects of the person and helping clients find meaning and purpose in their lives. Her goal was to create a supportive structure wherein families learn to understand the role they play with their loved ones and how they might best support those individuals in the healing of both the individual suffering and the entire family structure.

Rachel has a long-standing entrepreneurial and corporate background in various segments of the healthcare industry. Her career encompasses multiple facets of the healthcare arena including addiction treatment, managed care, third party healthcare claims administration and pharmaceutical benefits.

In addition to her administrative role at Healing Springs, she is actively involved in the treatment program.  She created and teaches the Leaders in Training curriculum, a weekly group, that helps clients identify their purpose at both the individual and community levels. The topics covered during this group experience include: understanding personality type and communication style, looking at skill sets and interests, identifying your own hero’s journey, prioritization and time management, leadership examples and styles, interviewing skills, resume writing, cleaning up credit, reviewing educational and background reports, and identifying life skills-stressors that could be triggering after discharge.

Rachel also facilitates the Executive Forum when needed which ties together personal growth and development to corporate leaders in treatment to better encourage peer to peer learning as it relates to the daily challenges of running a business both in and out of treatment.

Her personal experience with corporate America taught her that the same variables that create a healthy person are just as important in the workplace.  Much of what she teaches can be implemented in a corporate setting.

Rachel holds an MBA from LeTourneau University and a BBA from Baylor University and serves as a guest speaker and subject matter expert for various industries and currently speaks about addiction and her hero’s journey to professional organizations such as Young President’s Organization (YPO)  and Enterpreneuer’s Organization (EO) to name a few.

She also speaks passionately about the appropriate treatment for long-term sobriety through finding personal meaning and purpose. Rachel is a member of Young Presidents Organization (YPO) and has been interviewed and featured in various publications throughout her career and more recently in Inc. 500, Plaid for Women, Stagen Leadership Academy member Story and featured on the Coast to Coast Recovery radio broadcast.

Rachel enjoys spending time with her two children, her dogs, traveling, enjoying new cultures and cuisine as well as decorating her environments.
