Hello, and welcome. I'm a Licensed Clinical Social Worker dedicated to helping individuals navigate life's challenges while building resilience, confidence, and meaningful change. I earned my Master of Social Work from Arizona State University and have experience working with children, adolescents, adults, and families across a variety of settings.

My areas of focus include anxiety, depression, stress management, life transitions, self-esteem, relationship challenges, burnout, and trauma. I also have experience supporting foster, adoptive, and kinship families, as well as individuals navigating parenting and caregiving responsibilities.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a DNP (Doctor of Nursing Practice) degree from the University of Massachusetts Global. I have experience working with adolescents and adults in multiple settings facing various complex mental health issues, including OCD, depression, anxiety, ADHD and mood disorders.

Pleasure to meet you! My name is Iffy, and I was born and raised in Nigeria. After working in a Psych ER for over 22 years, I decided it was time to be able to treat my own patients. I went back to school and graduated from Brandman University in 2019 with my nurse practitioner degree. Four years later, I love what I do and the patients I treat. I truly believe that with the right work, tomorrow is always capable of bringing you a smile.

I'm a psychologist helping clients to navigate transition and overcome destructive patterns. I have expertise in treating anxiety, ocd, adhd, trauma, depression, addiction, recovery, and relationship challenges. I've had a private practice for over 10 years and work with adult clients at all stages of life. I earned my doctorate in Clinical Psychology at California Institute of Integral Studies, with intensive training at the Portia Bell Hume Center, Kaiser, UCSF, VA and the Jung Institute.
