Psychiatry in Saint Peters, Missouri Kari Hercules, Nurse Practitioner

Kari Hercules helps children, adolescents, teens, adults, and seniors across Missouri manage their mental health with thoughtful, individualized medication management at LifeStance Health. She partners closely with patients to reduce symptoms, improve daily functioning, and support long-term wellness for conditions such as anxiety, depression, and ADHD, using a compassionate and clinically grounded approach.

Her care is centered on understanding the whole person, not just the diagnosis. Kari specializes in anxiety, depression, and ADHD, and has experience supporting individuals with complex mental health needs, including those navigating trauma, mood disorders, and co-occurring conditions. She incorporates elements of Cognitive Behavioral Therapy (CBT) and mindfulness into medication management when appropriate, helping patients build coping skills alongside pharmacological support. Kari also serves diverse populations, including individuals with autism spectrum disorders, developmental disabilities, and members of the LGBTQ+ community, and offers additional areas of expertise to meet a wide range of mental health needs.

Kari is particularly dedicated to supporting individuals who have been recently discharged from a psychiatric hospital or are navigating court-ordered treatment. She understands the importance of continuity of care during these critical transitions and works to ensure patients feel supported, stable, and equipped with a clear plan as they move forward in their recovery journey.

Outside of her clinical work, Kari enjoys spending time in the sunshine, especially during spring and summer, and finds joy in gardening and bringing life to her home with flowers and plants. She also has a passion for cooking and loves exploring new recipes, finding fulfillment in sharing meals with others.
