In a landscape of large clinics and automated care, I offer a return to the old-school physician-patient relationship. Here, you aren’t just a chart number—you are a partner in your own wellness. I combine cutting-edge neuroscience with deeply human, evidence-based therapy to help you find lasting relief from anxiety, depression, and ADHD.

Why Work with a Solo Psychiatrist Instead of a Large Group?

While large clinics focus on volume... I focus on you.

Direct Access to Your Doctor

You work with me, the doctor, for every interaction —not a rotating staff of schedules, assistants, or nurse practitioners.

60-Minute Evaluations

I don’t rush. I take the time to understand your biological, psychological, and social history before we decide on a path forward together.

Integrated Therapy & Medicine

Unlike clinics that split your care between two different people, I can integrate both medication and therapy, ensuring your treatment is seamless and cohesive.

Specialized Psychiatric Services in Columbia & Beyond

Evidence-based treatments tailored to your unique needs.

Expert Medication Management

I provide strategic, conservative, and research-backed medication management for treatment-resistant depression, bipolar disorder, and anxiety. My focus is on maximizing your quality of life using the fewest medications possible and the lowest possible dose.

Adult ADHD Diagnosis & Treatment

Struggling with executive dysfunction? I provide thorough diagnostic testing and personalized treatment plans that go beyond prescriptions that include organizational strategies and behavioral support.

Specialized Therapy: CBT-i and ACT

I am one of only a few practitioners in the Baltimore area offering CBT-i (Cognitive Behavioral Therapy for Insomnia) and ACT (Acceptance and Commitment Therapy). These protocols are proven to work when traditional talk therapy has reached its limit.

Telepsychiatry in Maryland and Wisconsin

Access premier psychiatric care from the comfort of your home or office. I provide secure, HIPAA-compliant virtual visits for residents throughout both Maryland and Wisconsin.
