Alisa Tongg
Alisa is an award-winning Life-Cycle Celebrant, storyteller, founder, citizen of the Cherokee Nation, and an integrative guide who has spent her career helping people mark transformative moments with meaning. From her early work as a program director at MIT—where she coached students and alumni to tell their stories through resumes, cover letters, and interviews—to her years designing ceremonies that honor life’s thresholds, Alisa has seen how narrative shapes the way we step into the next chapters of our lives.
Building on this foundation, she trained at the SoundMind Institute as a Psychedelic Facilitator, deepening her capacity to hold space for altered states and profound experiences of transformation. Her work through The Inner Grove Collective is rooted in the understanding that integration is a narrative, creative, and ceremonial process.
By weaving ritual, storytelling, and community, Alisa helps people transform meaningful experiences into coherence, belonging, and direction—crafting stories that support healing, connection, and aligned forward movement.

Dr. Ashleigh Anderson, DO
Trained in Whole-Person Healing
Bridging medical expertise with integrative, relational, and transformative practices.
Dr. Ashleigh Anderson, DO is a board-certified adult, child, and adolescent psychiatrist whose work lives at the confluence of medical insight, relational attunement, and the deeper layers of human healing. For more than a decade, she has practiced within traditional psychiatric settings, providing diagnostic clarity and evidence-informed care, always grounded in steady, compassionate presence.
Witnessing people in their most vulnerable moments eventually illuminated a deeper truth: Healing is rarely a linear process and rarely confines itself to the mind, alone. Again and again, Dr. Anderson saw that people were seeking not only relief from their symptoms, but also a sense of understanding, a feeling of coherence, and a pathway back to themselves.
This insight reshaped her professional path. Dr. Anderson expanded her study into integrative and mind–body approaches, exploring how environments, relationships, and inner wisdom shape our capacity to heal. Her curiosity—and her patients’ lived experiences—eventually drew her toward a field where neuroscience, psychology, relational presence, and meaning-making come together in a more whole-person approach.
To anchor this work with rigorous training, ethical grounding, and a deep respect for safety throughout the preparation and integration process, Dr. Anderson trained as a psychedelic facilitator through the SoundMind Institute. There, she deepened her capacity to safely support altered states, guide internal exploration, and help individuals understand, integrate, and apply the insights that surface in expanded states of consciousness.
Across all her roles—psychiatrist, guide, educator, and collaborator—Dr. Anderson holds a core belief: that healing arises from within. Medicines and modalities may open the door, but transformation unfolds through a person’s own courage, clarity, and inner intelligence.
Her presence is often described as grounded, attuned, and precise in a way that feels deeply humane. Those she supports frequently note feeling understood without judgement and invited into a more compassionate, connected relationship with their own inner worlds.
Tisha Leslie
Tisha Leslie is a facilitator, community builder, and systems-aware guide whose work centers on healing, purpose, and our evolving relationship to work and meaning. She is a founding member of the Steamboat Springs chapter of the Nowak Society, where she has helped convene conversations around psychedelic therapy, mental health, and community-based healing in rural northwest Colorado.
Her professional background spans corporate brand strategy and marketing, primarily within technology organizations, where she spent years helping companies articulate their culture and values through the employee experience. Over time, this work sparked deeper questions about identity, burnout, and what it means to live a meaningful life within—and beyond—the professional grind. That inquiry led her toward a new chapter rooted in healing and connection.
Tisha is currently pursuing her Master of Social Work at Colorado State University and has completed psychedelic facilitator training through Sound Mind Institute. Her academic and practical interests focus on corporate burnout—especially among female executives and leaders navigating the intersection of ambition, caregiving, livelihood, and purpose.
Like many, Tisha’s path is shaped by personal loss, having lost more people in her life to suicide than to any other cause. While she values and continues to engage in talk therapy, it was plant medicine that helped her move through themes that years of 1:1 conversation alone could not fully reach. This lived experience informs her belief that healing often requires a thoughtful blend of modalities.
In 2025, she organized her practice under the name CO Creative Therapies, offering psychedelic preparation, facilitation, and integration services. Her work is especially oriented toward helping individuals explore their relationship to work, identity, and meaning—supporting moments of transition with care, humor, and grounded presence.
Raised in the woods of the Pacific Northwest, nature has always been home to Tisha, shaping her reverence for land, plants, and the wisdom of place. She moves between Washington and Colorado, following both personal roots and professional pathways. Colorado is where she is pursuing advanced education and licensure, and where state regulations allow her to practice as a certified facilitator, while Washington remains a touchstone of origin, restoration, and belonging. She works with clients throughout Colorado and virtually with individuals worldwide.
A mother to three sons, ages 13 to 29, Tisha brings a lived understanding of caregiving, complexity, and resilience into her work. Across all contexts, she is guided by the belief that healing happens through connection—to ourselves, to nature, and to one another—and that cultivating purpose and peace is a lifelong process, no matter the chapter of life.
