I am a functional psychiatrist provides an enhanced way to treat psychiatric conditions and care for the whole-person, not just their symptoms. My current positions are medical director in several inpatient and outpatient programs. Conventional psychiatry relies heavily upon pharmaceuticals to reduce or mask the symptoms of mental illness. It assumes nearly every illness is due to a neurotransmitter imbalance, and that medication will alleviate symptoms. However, there are far more factors that influence mental health than just neurotransmitters. Functional medicine can find the causes of your symptoms through special tests.

Do you feel like you’re doing everything "right," yet still feel weighed down by persistent stress, anxiety, or trouble focusing? You may be looking for more than a quick fix—you’re seeking a sense of clarity, stability, and control over your life again. My ideal client is someone who is trying their best but feels held back by "brain fog" or emotional exhaustion and is ready to discover what is truly driving their symptoms.
