With over 9 years of experience as a Psychiatric Mental Health Nurse Practitioner, I have had the privilege of supporting individuals from childhood through older adulthood in navigating mental health challenges. I specialize in treating a wide range of conditions, including anxiety disorders, OCD, PTSD, mood disorders (such as Major Depressive Disorder and Bipolar Disorder), psychosis, ADHD, ASD, and substance use disorders, including opioid and alcohol use disorder.

I bring a unique perspective to my practice as a Foreign Educated Physician and Pharmacist, which enhances my ability to provide thoughtful, holistic care. My approach is rooted in the biopsychosocial model, emphasizing patient-centered strategies that consider your mind, body, and environment.

I firmly believe in the possibility of recovery. Many of my clients are inspired to discover that, with adherence to an individualized treatment plan, meaningful progress and improved quality of life are achievable.

My goal is to create a safe, supportive space where you feel understood, empowered, and guided toward the mental wellness you deserve.

Something keeps pulling you back into the same patterns, the anxiety that returns no matter how much you manage it, the grief that hasn't had room to land, or the relationship dynamic you've tried to change but can't quite shift. I work with women navigating anxiety, grief, trauma, and relationship challenges, helping them understand what's driving those patterns and how to start making choices that come from the inside out. My approach pays attention to the whole person, including what your body is telling you, not just what your mind is saying. Clients often describe me as someone who helps them understand themselves in ways they hadn't expected.

Nice to meet you!

If you’ve been dealing with depression, anxiety, panic, sleep problems, or mood swings, you may feel worn down, stuck, or unsure what to try next. You want relief, but also clear answers, practical options, and someone who takes your concerns seriously. I work with young adults, adults, and seniors who are ready to better understand what’s happening and take steady steps toward feeling more balanced and in control of their mental health.

With 165+ reviews and a 4.96 rating on Zocdoc, I have specialized in advanced medication management for complex, treatment-resistant conditions. I utilize a neurobiological approach that focuses on frontal lobe/executive functioning, nervous system dysregulation, and neurotransmitter systems to diagnose and treat various concerns - ADHD/executive dysfunction, OCD, trauma/C-PTSD, high-masking autism, personality profiles, and cases where standard medication treatments have failed. While I specialize in clinical complexity, I bring that same deep, careful attention to treating anxiety, depression, and clients starting medication for the first time.
