Sea to Summit Psychiatry is structured to offer something rare in today’s mental health landscape: care that is deeply flexible, responsive, and built entirely around the needs of the individual.
Dr. Nate Miller maintains a small, focused caseload so he can be highly available to the people he works with. He’s known for being accessible and responsive—patients can reach out between sessions and know they’ll be heard. Whether someone prefers in-depth sessions, brief check-ins, phone calls, or even written reflections, Dr. Miller adapts to the format that works best. If a patient wants him to read and reflect on their journal, he’ll do it. If they need time to process something before or after a ketamine session, he’s there.
Because Sea to Summit is fully independent from insurance networks, treatment isn’t shaped by billing codes or time limits. The work can unfold naturally. Most patients begin with an in-depth intake session, followed by a few early appointments to build a strong foundation. From there, the rhythm of sessions is tailored to each person’s needs—whether that’s weekly therapy, occasional check-ins, or a more fluid model that shifts over time.
Dr. Miller collaborates closely with his patients throughout the process, whether the focus is therapy, medication support, psychedelic integration, or all of the above. He’s also happy to coordinate with other providers, including outside therapists, when it supports the patient’s goals.
At its core, Sea to Summit is about showing up—consistently, thoughtfully, and with genuine care—for whatever is most helpful in a person’s healing.
Dr. Nate Miller is a psychiatrist and founder of Sea to Summit Psychiatry, where he offers personalized, integrative mental health care.

Sea to Summit Psychiatry offers several specialized services designed to support deep, meaningful transformation. While every treatment plan is individualized, the practice includes focused offerings for people seeking innovative or integrative approaches to healing.
At-Home Ketamine Therapy
Dr. Nate Miller provides a unique, accessible model for at-home ketamine treatment. Unlike high-cost clinic infusions or lightly supported mail-order models, this approach blends affordability with real therapeutic depth. Patients receive careful preparation, clear guidance on how to use ketamine safely and effectively at home, and ongoing integration support—either with Dr. Miller or in coordination with another therapist. This model makes it possible for patients to do powerful inner work in a setting that feels familiar, grounded, and supportive.
Psychedelic Harm Reduction and Integration
Sea to Summit also offers support for individuals engaging with nontraditional psychedelic experiences. Dr. Miller takes a harm reduction-informed approach—providing education, psychological preparation, and post-experience integration to help individuals stay safe and make meaning of what arises. His clinical expertise allows him to support both the emotional and medical dimensions of this work, offering a grounded, nonjudgmental space for exploration.
Therapy and Medication Support
In addition to these specialized offerings, the practice provides ongoing psychiatric care that blends thoughtful medication management with depth-oriented therapy. Treatment is never formulaic. Dr. Miller brings curiosity, clinical skill, and flexibility to each session, helping patients move toward clarity, healing, and sustainable change.
