Stoni Johnston founded Sulcata Psychiatry to provide a personalized and connected experience for patients with mental health needs. Several years later, she joined up with co-owner Amanda Rogers, LCSW to provide more comprehensive care from a team approach. Stoni & Amanda believe that treatment should be approached as a nurturing relationship between provider and patient, and so they have sought to create an environment that removes traditional barriers that get in the way of communication and forming a relationship with your provider on a personal level, while still maintaining professional boundaries and standards of care.
Our providers create personalized treatment plans for ages 3+ that may include alternative, holistic, and conventional treatments for diagnoses such as autism, attention-deficit hyperactivity disorder (ADHD, anxiety, depression, post-traumatic stress disorder (PTSD), and bipolar disorders. We believe in combining the medical and therapeutic specialties to create a well-rounded integrated system of care, offering both medication management services as well as therapy services. When all providers are communicating regularly, it creates an environment of collaboration between our different specialties, and ultimately better outcomes and support for our patients.
All Sulcata Psychiatry providers believe in the research-backed notion that people respond better when they feel like their provider truly cares, listens, and makes them a partner in their mental health care plan. We get to know each patient as a whole person, not just a list of reported symptoms, so that we can celebrate every little victory with you along the way. Our entire team aims to always be responsive, accessible, kind, and understanding, so that we can meet you wherever you are in your mental health journey.
