The Black Onyx team makes mental health care easy to obtain, offering in-office care and telemedicine. They’re also personally accessible, providing hands-on care that includes texting with patients needing intervention.

The team treats the full scope of mental health disorders, ranging from anxiety and depression to bipolar disorder and post-traumatic disorder (PTSD).

Peter and Diana specialize in attention-deficit/hyperactivity disorder in adults, providing medication, therapy, and support that improves each person’s ability to succeed on the job, at home, and in their relationships.
