Who we help
Care for a focused range of adult concerns
Treatment is shaped around your symptoms, history, and goals — not a one-size protocol. These are the areas this practice most often supports.
Bipolar spectrum concerns
Shifts in mood, energy, and sleep, and questions about diagnosis and long-term treatment.
Anxiety, panic & OCD
Excessive worry, panic, and intrusive thoughts or compulsions that disrupt daily life.
ADHD & attention concerns
Difficulty with focus, organization, and follow-through — evaluated carefully before treatment.
Insomnia & sleep disruption
Trouble falling or staying asleep, and the effect of sleep on mood and functioning.
Psychosis-spectrum concerns
Unusual experiences in thinking or perception, assessed thoughtfully and without alarm.
Consultation & second opinions
A focused review of diagnosis or medication, often in collaboration with your current clinician.
Our approach
Careful, collaborative, and individualized
Psychiatric treatment works best when it is built around the person. Three principles guide care at Prospect Park Psychiatry.
Diagnostic clarity
Time taken to understand what is actually going on before deciding what to do about it.
Medication used thoughtfully
Prescribed when it is genuinely useful, reviewed over time, and never on autopilot.
Attention to the whole picture
Sleep, daily functioning, and the therapeutic relationship all shape the outcome.
