Psychedelic Assisted Therapy
Psychedelic-assisted therapy is an emerging approach to mental health treatment that combines evidence-based psychotherapy with the therapeutic use of psychedelic medicines in carefully structured, legally approved settings. Rather than focusing solely on symptom reduction, this approach can help individuals access deeper emotional healing, gain new perspectives, and process experiences that may have felt difficult to reach through traditional therapy alone.
Research continues to demonstrate promising outcomes for conditions such as depression, anxiety, post-traumatic stress, grief, and existential distress when these therapies are provided by trained clinicians. Treatment is grounded in careful preparation, supportive therapeutic guidance, and thoughtful integration to help translate insights into lasting change.
At Harbor Clinical Services, psychedelic-assisted therapy is offered in accordance with current laws, ethical standards, and evolving clinical research. As new therapies become legally available, our practice is committed to providing safe, compassionate, evidence-based care using the highest standards of clinical practice.

Frequently Asked Questions
What is Ketamine?
Ketamine is a safe, legal, and well-researched medication that has shown remarkable effectiveness in treating depression, anxiety, PTSD, and other mental health conditions, often providing relief more quickly than traditional antidepressants. It works by promoting neuroplasticity (the brain's ability to form new neural connections) and temporarily quieting the brain's default mode network, which is associated with rumination, negative self-talk, and rigid patterns of thinking. This creates a unique opportunity for greater emotional flexibility, deeper self-reflection, and meaningful therapeutic work. When combined with psychotherapy, ketamine can help individuals process difficult experiences, gain new perspectives, and create lasting positive change.
Is Ketamine safe?
Yes. Ketamine has been used safely in medical settings for more than 50 years and has a strong safety profile when managed by trained medical professionals. Before treatment, you'll complete a thorough medical screening to ensure ketamine-assisted psychotherapy is appropriate for you, and you'll be closely monitored throughout the process. When combined with psychotherapy in a carefully supervised clinical setting, ketamine can be a safe and effective treatment option for many individuals.
Is Ketamine-Assisted Psychotherapy (KAP) right for me?
Ketamine-assisted psychotherapy may be a good option if you're struggling with depression, anxiety, PTSD, trauma, grief, or other emotional challenges, especially if traditional therapy or medications haven't provided the relief you were hoping for. KAP is not appropriate for everyone, which is why the process begins with a comprehensive consultation and medical screening to determine whether it's a safe and appropriate fit for your unique needs. If KAP isn't the best option for you, we'll discuss other evidence-based approaches to support your healing and recovery.
What does Ketamine-Assisted Psychotherapy cost?
The cost of KAP varies based on your individualized treatment plan, including the number and length of preparation, dosing, and integration sessions. During your initial consultation, we'll discuss your goals, answer your questions, and provide a clear estimate of the expected costs before beginning treatment. We believe in transparent pricing and will work with you to develop a plan that best supports your therapeutic needs.
