Meet Our Administrative Staff

    Cathleen Buchanan, MA, PA
Interim President

Cathleen Buchanan has a proven executive and management track record and over twenty-five years of experience developing sales and growth in the healthcare market. Prior to joining the team at The Graduate Institute, Cathleen was Vice President of Marketing and Business Development for National Healthcare Associates, a network of 26 facilities with approximately five thousand beds throughout four Northeastern States. Previously she served as Executive Director of New Business Development for New England Home Care, a $100 million company that offers homecare services throughout Connecticut. Cathleen also served as President of Professional Relief Nurses and Staffing Company where she stabilized the company and managed a successful turnaround. The evolution of her career began in hands-on care as a physician's assistant and moved into management as the continuum of care began to move the patient out of the hospital into the post-acute market.

Cathleen has spent her entire career in Western medicine, deeply committed to providing care for patients, advocating for both patients and the staff from the executive suite.

As Alum of The Graduate Institute she now looks to honor what has been accomplished by the visionary founder some twenty years ago and lead the team into its next chapter of development and the ever evolving need for a holistic approach to health.

Long before the rise of Western medicine, compassionate leaders devoted their lives for whole body wellness and Cathleen embodies that philosophy. Her leadership and fierce dedication to the importance of intention, attitudes and beliefs is inspirational and needed in today’s world.

Cathleen is a Board Certified Physician’s Assistant, graduating Cum Laude from the Medical College of Georgia and holds a Master of Arts Degree in Integrative Health and Healing from The Graduate Institute.
