Our Story
Meet Your Provider
Rebecca Jaiyesimi, MSN/MHA, APRN, PMHNP-BC
Rebecca Jaiyesimi is a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and the founder of MindOak Psychiatry. A nurse since 2007, she brings over 19 years of nursing experience to her practice, including more than 8 years in behavioral and mental health and the past three years as a Psychiatric Mental Health Nurse Practitioner providing evidence-based psychiatric care to adolescents and adults throughout Texas.
Rebecca specializes in comprehensive psychiatric evaluations and medication management for a wide range of mental health conditions, including depression, anxiety disorders, ADHD, bipolar disorder and other mood disorders, PTSD and trauma-related conditions, insomnia and other sleep disorders, and substance use disorders. She sees patients in person at her McKinney, Texas office and through secure telehealth appointments across the state.
Rebecca believes exceptional mental health care begins with listening. Her visits are unhurried by design: each appointment combines careful medication management with supportive therapy, patient education, and practical strategies, because treatment works best when you understand it and helped choose it. Medication decisions are made with her patients, with the options and trade-offs explained in plain language, never handed down. For patients who would benefit from ongoing weekly psychotherapy, she coordinates referrals to trusted licensed therapists while continuing psychiatric medication management, so every part of your care works as one plan.
Her passion for mental health is rooted in both her professional experience and her personal understanding of life’s challenges. Guided by her Christian faith, Rebecca approaches every patient with empathy, dignity, and compassion while honoring each individual’s personal beliefs and values. She is committed to creating a safe, welcoming environment where patients feel heard, respected, and empowered.
At MindOak Psychiatry, Rebecca’s mission is simple: accessible, high-quality psychiatric care that helps people overcome challenges, build resilience, and thrive. Whether you are seeking support for anxiety, depression, ADHD, bipolar disorder, trauma, or another mental health concern, she is dedicated to helping you achieve lasting wellness through personalized, compassionate care.
