About Us

Innovative Approach to Psychiatry

Fermata is the name of a musical notation that indicates a rest should be paused beyond its natural duration. We believe in stopping help that has not been helpful, pausing, and approaching individuals with mental illness from new perspectives with innovative approaches. Accelerated Transcranial Magnetic Stimulation, where remissions from lifelong suffering can happen in the span of a week instead of months, is one such approach. Mentalization Based Treatment, a therapeutic approach that works for individuals with complex and life-threatening problems when nothing else has, is another. We encourage you to reflect on what embracing a fermata could look like for you and make space for one in your life.

Our Practice Areas


Transcranial Magnetic Stimulation for Mood Disorders and OCD

Expertly crafted neuromodulation protocols to fit a wide range of diagnoses, schedules and ages. This includes accelerated TMS with and without fMRI guidance, deep TMS and theta burst protocols.

Monarch eTNS System for ADHD

FDA-approved non-invasive neuromodulation for children ages 7-12 with ADHD. This can also be used for individuals outside this age range if appropriate.

PRISM Neurofeedback for PTSD

An FDA cleared in-office protocol that uses neurofeedback to treat symptoms of PTSD. This noninvasive neuromodulation device trains patients to control key neural connections between the amygdala and frontal cortex to boost their emotional regulation and stress resilience.

Gammacore nVNS for Anxiety and PTSD

An at home neuromodulation device FDA cleared for a variety of headache types and with breakthrough device status for PTSD (used off-label for anxiety and PTSD at present).

Clinical Supervision & Education

Ongoing consultation or didactics around therapeutic and interventional psychiatric approaches and business and technology of healthcare concerns

Second Opinion Consultation

Comprehensive diagnostic assessment and treatment recommendations for individuals and families seeking a path forward amidst uncertainty.

"For the highest level of expertise in TMS, New York City clinicians look to the guidance of Dr. MacMillan and Dr. Muir for their leadership in this innovative and important FDA-approved treatment. It is an excellent treatment option for those who need rapid, effective results without the ongoing use of medication. The duo has been instrumental in helping patients gain access to an extremely effective treatment for depression and OCD, and it's clinical indications continue to expand."

Frequently Asked Questions

Are all sessions in-person or is telehealth available?

While TMS sessions are in person, the vast majority of appointments are conducted over telehealth. There are clinical circumstances and regulations around controlled substance prescribing where an in-person appointment is more appropriate. We work with patients and families around these situations. Please note that we are only able to conduct telehealth sessions in states where we are licensed.

How does communication work in between sessions?

At Fermata, we recognize that most of life happens outside of sessions and so we are able to communicate via secure text messaging or phone calls regarding urgent and logistical matters. We also recognize that accessing emergency services and psychiatric hospitalizations, while life-saving in some circumstances, can be life destroying when turned to in a reflexive, knee-jerk fashion. That is why we prioritize being available when crises arise to work collaboratively around getting help that is actually helpful.

Can I use my insurance at Fermata?

At this time, our clinicians are out-of-network with most insurance plans in order to provide the quality and type of care that we can stand behind. Dr.Muir is in network with Cigna and Medicare and Dr.MacMillan with Medicare but not all services (e.g. accelerated TMS) are covered by insurance. In parallel, we advocate at the national level around increasing mental health parity and accessibility to quality mental health care. We hope to in the future be able to work more in an aligned way with more payers and stakeholders. Meanwhile, we do provide "superbills" upon request for out-of-network reimbursement for covered services if your plan has this benefit (e.g. a PPO plan). We are happy to provide guidance around plan selection. Our technology partner, Osmind, can also submit these superbills to insurance companies on your behalf if you prefer.

What forms of payment does the practice accept?

We accept all major credit cards, HSA/FSA cards, checks, cash, wire transfers/ACH payments and even cryptocurrency!

Are you hiring and do you work with trainees?

We are happy to partner closely with therapists interested in working in a collaborative model but are not hiring for staff therapists at this time to work directly at the practice. We are able to serve as supervisors for trainees or those with provisional licenses, however, depending on the circumstances. If you are trained as a deep TMS Technician or have a strong interest in getting this training, we are looking for more part-time technicians to work with our patients. To inquire about available opportunities, please contact us at
