Mental health has been an important part of my journey from the very beginning. I graduated from the University of St. Francis while working in inpatient behavioral health, where I learned how meaningful it is to meet people with kindness, patience, and understanding during difficult moments. I spent time working in medical-surgical settings to broaden my experience, but I was drawn back to mental health because it’s where I feel most connected to my work.
I provide care through telehealth and aim to make virtual visits feel as comfortable and easy as possible. I know it can take time to feel at ease talking through a screen, and I focus on creating a space that feels supportive, relaxed, and judgment-free. I take a collaborative approach, listening closely and working with you to find treatment options that fit your needs and your life.
I work with children, adolescents, and adults experiencing anxiety, depression, ADHD, OCD, mood disorders, and related concerns. My goal is for you to feel heard, respected, and supported as we work together toward feeling better and more balanced in your day-to-day life.

Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding psychiatrists in Arlington Heights starts with knowing which type of mental health care fits your needs. Psychiatrists and psychiatric mental health nurse practitioners can diagnose conditions and prescribe medication, while therapists focus on talk therapy. If you’re looking for support with anxiety, depression, attention-deficit/hyperactivity disorder, bipolar disorder, obsessive-compulsive disorder, or medication management, psychiatric care may be one option to consider. Review each psychiatrist’s listed specialties, background, and care focus to see whether their training matches what you want help with.
Arlington Heights has local psychiatry options, but availability can vary by schedule, location, and appointment type. Virtual appointments can expand your choices beyond nearby offices while still helping you stay within your insurance network. Psychiatric medication management visits are usually shorter and less frequent than therapy sessions, though some psychiatrists also offer therapy. Some people work with both a therapist and a prescriber, so it can help to read bios for details on appointment structure, communication style, and whether a free phone consultation is offered.
Psychiatric care in Arlington Heights can be a significant expense without insurance. Using in-network coverage is one of the most reliable ways to reduce session costs and understand what you may pay before booking. Headway helps you search for psychiatrists who are accepting new patients with your plan, compare profiles, see estimated out-of-pocket costs upfront, and book directly when you’re ready.
If you're already taking psychiatric medication and considering switching providers, talk to your current prescriber before changing or stopping any medication — most psychiatric medications shouldn't be stopped abruptly. Anyone experiencing thoughts of self-harm or in acute crisis should call 988 or go to the nearest emergency department rather than wait for an outpatient appointment.
