I seek to provide culturally affirming, holistic care that integrates the mind, body, and spirit. As a multicultural, neurodivergent psychiatrist and daughter of immigrants raised in Chicago, I bring both clinical training and lived experience to our work together. My own journey through burnout and the process of learning to slow down and listen to what my body needed has also shaped the care I provide. It has grounded me in genuine curiosity, humility, and a deep respect for the wisdom you already carry.
I am a compassionate psychiatric provider that is dedicated to my practice. I started my psychiatric career as a technician in forensic psychiatry. I worked with individuals who had comitted crimes and were either attempting to determine competency, or were found not guilty by reason of insanity. As my education blossomed, I began working as a nurse on a child and adolescent crisis stabilization unit. I found a massive love for child and adolescent psychiatry and spent most of my career working crisis stabilization and residential psychiatric care for children and adolescents. This gave me significant experience working with many different cultures. After I graduated with my doctorate, I began working psychiatric outpatient. I now see patients of all ages (children 4+, adolescents, adults and geriatric). I thrive on a strong therapeutic relationship and making sure my patients feel heard. I am open minded and non-bias. You are safe with me.

Choosing the right provider is a big step, and I'm here to offer a unique blend of expertise and genuine support. I'm a dual board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP) and Family Nurse Practitioner (FNP), and a Certified Advanced Practice Addictions Nurse. What does this mean for you?

My clinical approach is collaborative, warm, and rooted in evidence-based practices.
