Hello! I'm Idowu Mary Oni, a Board-Certified Psychiatric Nurse Practitioner (PMHNP-BC) committed to delivering personalized, compassionate mental health care. With a strong foundation in nursing, I specialize in supporting individuals as they navigate mental health challenges and work toward greater emotional well-being. I'm honored to be part of your journey and look forward to helping you reach your goals with care and understanding.
Do you have a stack of partially read self-help books collecting dust in the corner? Maybe you had hopes they would provide the information you were seeking to stay cool and collected through challenging times - because let’s face it, 2020 was pretty much a shitshow. It is alright to feel overwhelmed, confused, and uncertain, just know you don’t have to stay in that place. Whether you are looking for coping strategies to build resiliency through life transitions or wanting to explore deeper parts of yourself and how you relate to the world, I would be honored to walk along side you in your healing journey to find your authentic self. We can work together to create transformational change.
I wholeheartedly believe in the ability for people to make changes regardless of life circumstances. Our sessions will be filled with humor, empathy, and compassion as we focus on making progress towards your desired outcome.
I have 12 years of vast clinical experience. I am trained in Somatic and Attachment Focused (S.A.F.E.) EMDR. I am a Licensed Professional Counselor, Licensed Addiction Counselor, and hold a specialized credential for intimate partner violence. I am a certified as a Clinical Trauma Professional Level II, Advanced Grief Counseling Specialist, Clinical Anxiety Treatment Professional, and Clinical Telemental Health Provider. I’m also a National Certified Counselor. All this really means is that I may have some information you find useful.
Our sessions will begin at a pace that feels comfortable for you. I specialize in an integrative, holistic approach to depression, anxiety, trauma, and coping with life challenges. My therapeutic approach blends humanistic, mindfulness, somatic work, deep spiritual inquiry, CBT, and psychodynamic therapy, tailored to each client’s unique experiences.
