MEET THE TEAM
Executive Director
Susan Buchholz
Susan joined HeartWell in March of 2024 after three decades in the non-profit sector where she found her calling, advocating for health equity and social justice. From an early age, Susan felt a deep sense of responsibility to speak up for those she perceived as vulnerable to harm or neglect, a value that has guided her career and personal choices.
Susan is an enthusiastic community connector and communicator, who seeks out opportunities to bridge diverse perspectives, by finding common ground between seemingly disparate viewpoints.
Her approach not only exemplifies her commitment to social advocacy but also underscores her belief in mindfulness as a cornerstone for personal and professional growth.
Susan attributes her journey towards resiliency and hopefulness to her practice of Vipassana meditation, a discipline she has embraced for many years to maintain her well-being.
Susan holds a BS in human service management from Leslie University, Cambridge, MA, and is working towards her master’s in public health at Johns Hopkins University in Baltimore, Maryland. She is a Bloomberg Fellow with a concentration in addiction and overdose.
Susan views mindfulness as a journey rather than a definitive endpoint, highlighting the importance of embracing imperfection in oneself and others as a pathway to peace.
May all beings be happy.
May all beings be peaceful.
May all beings be liberated.
