GTMH - Key Persons


Carla Joseph

My name is Carla Joseph I am a board-certified Psychiatric Mental Health Nurse Practitioner. I maintain a comprehensive focus to care, including brief psychotherapy and prescribing mental health medications if indicated, for all ages. Overall I tend to be more conservative in my prescribing practices, especially in regards to prescribing controlled substances such as benzodiazepines or even stimulants. I started my mental health career working as a psychiatric registered nurse twelve years ago in one of the largest correctional systems in the United States. Eventually, I then went on to complete my Masters in Science of Nursing Degree in psychiatric mental health. In addition, prior to becoming a nurse practitioner, I worked in a variety of healthcare settings as a registered nurse including Adult and Pediatric Oncology, Surgery, and Infection Control Preventative. My training experiences in a large metropolitan area have ignited a passion to provide access to affordable, quality mental health care no matter where a patient may be located. As a Psychiatric Mental Health Nurse Practitioner, I will offer a wide range of mental health treatment from complex trauma/PTSD, mood disorders, anxiety, and ADHD.
