John Ernzen

Dr. John Ernzen is a trained adult psychiatrist. He completed his undergraduate studies at Arizona State University and earned his medical degree from the Feinberg School of Medicine at Northwestern University. He is completing his general psychiatry residency at the University of Illinois at Chicago after which he will begin additional training in child & adolescent psychiatry at Northwestern.
He specializes in evidence-based psychiatric care, most notably focusing on mood & anxiety along with neurodevelopmental disorders. He is well-versed in all classes of psychotropic medications and their indications, though he rarely prescribes controlled substances (stimulants, benzodiazepines, etc) on an initial visit. Above all he values the human component of psychiatry and making a connection with his patients – he knows that it’s often important to meet people where they are at, and appreciates the convenience of telepsychiatry in helping him do so.
