Cambridge Biotherapies™

Cambridge Biotherapies™, founded in 2016 by Daniel A. Brenner, M.D., was born out of a desire to help people who have tried traditional psychiatric treatments, such as medication and psychotherapy, with limited success.

We are a private treatment center committed to providing a uniquely warm, compassionate, welcoming, and comfortable environment. We are careful and thorough, and honor the dignity of every human being we work with, regardless of their background, circumstances, or identity. We maintain exemplary medical standards and incorporate developments from the most current research in a never-ending quest to improve our outcomes. All of our team members are highly skilled, carefully selected, have specialized training, and bring years of dedicated experience to their practice.

Revolutionary Mental Health Treatment

Ketamine Infusion Therapy

Ketamine is a fast-acting antidepressant that can substantially reduce depression symptoms in hours or days rather than weeks. Ketamine is a well-studied, empirically-validated, and highly effective treatment. In up to 70% of cases, ketamine can dramatically relieve depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms, sometimes following a single infusion.

Psychedelic Therapy

Ketamine-Assisted Psychotherapy (KAP), a form of psychedelic therapy, can be a transformative experience. It does not need to replace any current therapy or treatment and is best used as an adjunctive treatment in the context of ongoing psychotherapy. Nevertheless, there are some patients who benefit from a course of KAP even though they are not currently engaged in another psychotherapy or treatment plan. Ketamine-assisted psychotherapy employs three types of sessions: preparatory, medication, and reflection (sometimes referred to as “integration”). Our treatment plans are individually tailored to each patient.


TMS is a powerful treatment option for those seeking an approach that does not involve medication. TMS is a safe, FDA-cleared approach that is largely free of side effects and twice as effective as traditional antidepressants for symptoms of depression and anxiety. Many people achieve remission from depression and anxiety in days to weeks with multiple treatments.

Accelerated TMS

A recent study at Stanford demonstrated that when TMS was delivered in a more intensive schedule and accelerated pace, it provided remission from depression in 90% of patients in as little as 3 to 5 days. We treat patients using the same parameters used in the Stanford study. Our approach uses an effective office-based method of finding the treatment location, called direct brain mapping, rather than a combination of MRI and computer modeling used in the original studies.

Consultation / Medication Management

Medication management begins with an initial consultation, during which one of our staff members will take time to understand what you’re struggling with, what matters to you, and what we can do to help. We then develop a treatment plan and meet as often as necessary to follow up and ensure that we are making progress. Our approach is collaborative, respectful, compassionate, and patient-focused. We work individually with each patient to develop a plan, and coordinate with outside providers and family members whenever our patients feel that would be helpful.
