My name is Tammy, and I am a board certified by the American Nurses Credentialing Center as a Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over 15 years of experience in mental health.
I want to meet my patients where they are and want them to feel safe and supported. I believe that outcomes are best met when there is mutual trust, respect, honesty, and patients know that they are being heard.
Ola Omoniyi became an Illinois Certified Nurse Practitioner in 2021. She received her undergraduate degree at Valparaiso University in Indiana and her master’s degree from the University of St. Francis in Joliet. She completed her clinical rotation in mental health at Will County Behavioral Health in Joliet. Ola worked at Rush University Medical Centre for 5 years in the behavioral health unit as a Registered Nurse and 5years at other behavioral health hospitals in Chicago.
My nursing career began in 2010 when I first became a Registered Nurse. In 2017 I graduated from Maryville University in St. Louis, MO with my master’s degree in nursing and became a board-certified Family Nurse Practitioner (FNP-C) licensed in Illinois. I have been blessed to work in many facets of healthcare since and has also become a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC). With a strong foundation in both primary care and mental health, my approach aligns overall wellness and hormone optimization with physical, mental, and lifestyle well-being.
