In the center of Niwot, along a quiet stretch of town that feels both grounded and quietly alive, sits The Healing Collective—a functional and integrative health practice founded by Tracy Shulsinger, FNP-C. People often describe an immediate sense of ease when they walk in, as if the space itself invites them to breathe differently. For many, it is the first place they’ve felt truly seen.

The practice supports individuals seeking deeper wellness, hormonal and thyroid balance, detoxification, nervous system resilience, and long-term vitality, as well as those navigating chronic or complex conditions. At its foundation is a simple truth: healing grows through connection—within the body and between people.

The Foundation of Healing: A Philosophy of Alignment

A defining aspect of The Healing Collective is its emphasis on foundational health. Care begins with the essential pillars—balanced hormones and thyroid function, nourishing nutrition, movement, restorative sleep, emotional steadiness, and a regulated nervous system. These elements create what the practice calls a “healing state,” a physiologic and energetic terrain in which the body can repair, adapt, and respond to deeper therapeutic work.

“When the foundation is strong,” says Tracy Shulsinger, FNP-C, “everything else becomes more effective. We don’t want to chase the rare or obscure before restoring the basics that allow the body to heal.”

Once this groundwork is in place, the practice moves with precision into deeper layers such as chronic infections, toxin burden, autoimmune activation, metabolic shifts, mold and environmental exposures, and the subtle patterns that are often missed elsewhere.

Functional Medicine: Listening Below the Surface

Functional medicine at The Healing Collective begins with attentive listening. Practitioners explore how the body’s systems communicate—how hormones affect sleep, how toxins influence mood, how the thyroid steers metabolism, and how the nervous system shapes digestion and immunity. Nothing is treated in isolation.

A highly investigative, lab-guided process is central to the clinic’s work. Advanced testing reveals what symptoms alone cannot: inflammation, chronic infections, nutrient depletion, hormonal and thyroid imbalances, toxin accumulation, and immune dysregulation. With this clarity, treatment becomes not a guess but a thoughtful, individualized path.

Detoxification is deeply woven into care, especially for those affected by mold, heavy metals, chemical exposures, or chronic infections. Support is gentle, paced, and physiologic, helping the body clear what burdens it while strengthening long-term resilience.

Integrative medicine expands this work with nutrition, nervous system support, sleep restoration, IV therapy, peptides, ozone therapy, and mind–body modalities. The practice incorporates Frequency-Specific Microcurrent (FSM) and Pulsed Electromagnetic Field Therapy (PEMF) to calm inflammation, enhance cellular communication, support tissue repair, and help the nervous system settle into safety.

Tracy’s background in energy healing and shamanic training brings an additional dimension to her work. Though the practice is grounded in functional and integrative medicine, her intuitive and energetic perspective helps patients feel understood on deeper emotional and spiritual levels.

A Practice Rooted in Relationship

The Healing Collective grew from a vision of care centered on humanity. Patients often describe feeling heard in a way they haven’t experienced elsewhere. Precision is paired with presence; science is paired with compassion. Treatment unfolds at a pace the body can hold, honoring physiology, intuition, and each individual’s lived experience.

“Healing happens through relationship,” Tracy shares. “It happens when people feel safe, understood, and met where they are.”

A Team That Broadens What’s Possible

While the practice is anchored in its integrative medical foundation, The Healing Collective is supported by a small, highly skilled team.

Dr. Madelyn Lamar Altman, PT, DPT offers advanced physical therapy including FSM, PEMF, visceral manipulation, pelvic floor therapy, and full-body musculoskeletal work—creating structural and nervous system shifts that complement the medical care beautifully.

Two experienced IV nurses bring clinical excellence and a grounded, nurturing presence to the practice’s infusion therapies.

Each team member adds depth to the work, yet the practice remains unified through a shared philosophy of foundational healing, investigative clarity, and connection.

Why People Come

People seek out The Healing Collective for many reasons: hormone and thyroid challenges, toxin exposures, chronic fatigue, infections, immune dysregulation, digestive issues, mood shifts, sleep disruption, brain fog, inflammation, and nervous system imbalance. Others come simply to feel more vibrant—to sleep more deeply, think more clearly, move through life with steadiness, or reconnect with a sense of inner vitality.

Across all experiences, the goal remains the same: to help people feel more like themselves again.

Tools That Support Transformation

IV therapy, peptide therapy, and medical ozone serve as powerful adjuncts when foundational work is strong. They replenish depleted systems, enhance detoxification, stabilize inflammation, support metabolism and thyroid function, strengthen immunity, and help the body shift into deeper alignment.

“These therapies aren’t quick fixes,” Tracy notes. “They’re catalysts that help the body step more fully into its own healing potential.”

An Invitation Into a Different Kind of Care

Healing at The Healing Collective is integrative, relational, and deeply human. Patients are welcomed with presence, treated as partners, and supported with both scientific rigor and heartfelt compassion. It is a place where foundations matter, where listening shapes treatment, and where healing unfolds through connection.

When the body is supported system by system—and when care honors both physiology and spirit—health does more than improve.
It becomes vitality.
