Find a psychiatrist in Illinois — covered by insurance

As a board-certified PMHNP, I believe prioritizing mental health is key to happiness and stability in life. Seeking help can be one of the hardest parts, so congratulations on taking that step!

I take a unique, integrative approach to mental health care. Whether you’re a child or adolescent navigating anxiety and ADHD or a veteran or 1st responder managing stress and emotional challenges, I tailor my care to your individual needs. I combine Eastern herbs, nutritional supplements, prescription medications, and personalized nutrition plans to create a treatment model as unique as you are.

My goal is to help you build confidence, improve focus, and achieve balance in all areas of life—whether that’s excelling at school, enhancing job performance, or strengthening relationships. Together, we’ll create a path toward emotional well-being and a healthier, more fulfilling life.

My educational journey reflects my commitment to integrative and holistic care. I earned a Bachelor’s degree in biological and nursing sciences, a Master’s in acupuncture science, and a Doctorate in chiropractic medicine from the National University of Health Sciences, where I developed a strong foundation in Eastern medicine and natural therapies. I am a double board-certified nurse practitioner specializing in family and psychiatric mental health.

I am compassionate, approachable, and committed to providing a safe, nonjudgmental space. I value open communication, transparency, and collaboration, and I believe treatment works best when we make decisions together. My care is evidence-based and trauma-informed, focused on understanding the whole person and supporting meaningful, sustainable mental health improvement.

With over 12 years of experience in nursing and behavioral health, I provide comprehensive psychiatric evaluations and medication management for children, adolescents, and adults ages 6 and older. My clinical interests include ADHD, anxiety disorders, depression, bipolar disorder, trauma-related conditions, stress-related concerns, and mood disorders.

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? It means I can offer truly integrated care, understanding how your physical and mental health are connected, and providing specialized support for addiction.

As one of the country’s few psychiatrists who also practices sex therapy, I can provide unique and specialized services for patients who have been marginalized and oppressed. I offer a combination of sex therapy and medication management, tailored to both your personal and medical needs. While I predominantly follow an Acceptance and Commitment Therapy (ACT) approach, I also incorporate elements of psychodynamic psychotherapy, Cognitive-Behavioral Therapy (CBT), trauma-informed therapy, and supportive therapy. I completed medical school at the Indiana University School of Medicine (2021), and completed psychiatry residency training at University of Chicago (2025).

I treat 18+ individuals, and specialize in treating individuals within any sexual minority group — including members of the LGBTQIA+, trans, gender-expansive, non-monogamous, and kink communities — plus those who participate in unconventional sexual practices. I also treat couples and individuals within various relationship structures (such as triads, polycules, or other non-monogamous relationships).
