Our Approach
Ketamine-assisted therapy is most effective when bookended by preparation and integration. Our process ensures your experience leads to lasting change.
Every journey begins with a comprehensive medical and psychological evaluation. We take time to understand your history, set clear intentions, and prepare your nervous system so the experience feels safe, grounded, and purposeful.
Sessions are conducted in a calm, private, and closely monitored clinical setting. Lauren provides personalized dosing and is present throughout to ensure your safety and comfort at every moment.
The insight that emerges during a ketamine session is only the beginning. Integration sessions help you process, embody, and translate the experience into meaningful, lasting change in your daily life.
Ketamine therapy is woven into your broader care plan, including nervous system regulation, functional psychiatry, and ongoing support so healing extends far beyond the session itself.

Frequently Asked Questions
Ketamine-assisted therapy combines the therapeutic use of ketamine, a medication with rapid-acting antidepressant properties, with psychotherapy and integration support. It works through a different mechanism than traditional antidepressants, often helping people who have not responded to other treatments.

The number of sessions varies based on your individual needs and treatment goals. Lauren will recommend a personalized protocol during your consultation, including preparation, the ketamine sessions themselves, and ongoing integration support.
When ketamine is used appropriately and under the care of a trained medical provider, it has a well-established history of medical use. Like any medication, ketamine can have risks and side effects, which is why careful screening, appropriate dosing, monitoring, and having safety protocols in place are so important.
Lauren has worked with ketamine in clinical practice since 2017 and has experience not only providing direct patient care, but also supporting ketamine safety protocols and provider training. She is also trained in Basic Life Support (BLS) and Advanced Cardiovascular Life Support (ACLS).
At Deep See Wellness, safety begins before your first treatment. Lauren reviews your medical and psychiatric history, medications, and potential risk factors to determine whether ketamine is appropriate for you. During treatment, you are monitored and supported throughout the experience, with established protocols in place should you need additional medical attention.
