Board-Certified Adult Psychiatry · Norman, Oklahoma
Expert Medication Management for Adults
Board-certified adult psychiatry for depression, anxiety, and ADHD — in person in Norman, OK and by telehealth across Oklahoma and Texas. Personalized care, booked online in minutes.
Care that starts with listening
Every treatment plan begins with a thorough evaluation and your goals — then careful, evidence-based medication management with a physician who knows you.
Depression
Feeling empty, unmotivated, or hopeless is not something you have to push through alone. We work with you to find the treatment that fits — and we adjust until it does.
Depression care →Anxiety
Persistent worry, panic attacks, a racing heart, restless nights. Anxiety is highly treatable — thoughtful medication management can help you feel like yourself again.
Anxiety care →Adult ADHD
Trouble focusing, planning, or finishing what you start? Trouble focusing is often driven by depression, anxiety, poor sleep, or something else entirely, so the first step is a careful evaluation to sort out what’s going on — then a treatment plan built around your life.
