First Quarter Mental Health

First Quarter Mental Health is a locally owned psychiatric practice founded by Yvonne MacKillop, PA-C, and Todd MacKillop, PA-C. First Quarter Mental Health was built on a shared passion for helping individuals and families access compassionate, high-quality mental health care. As married Physician Assistants with more than 30 years of combined experience in medicine, Yvonne and Todd bring a deep understanding of healthcare and a commitment to serving their community. Under the clinical leadership of a board-certified child, adolescent, and adult psychiatrist, our practice specializes in individualized psychiatric medication management delivered with compassion, respect, and collaboration. We believe effective mental health care begins with listening, recognizing each person’s unique strengths, and creating treatment plans tailored to their individual needs and goals. At First Quarter Mental Health, we proudly provide neurodiversity-affirming care and strive to create a welcoming environment where every client feels seen, heard, and valued. Our philosophy is simple: Different, Not Deficient.
Supported, Not Judged. We believe mental health treatment should be empowering, evidence-based, and centered on helping people thrive. Whether you are seeking support for yourself or a loved one, we are committed to partnering with you every step of the way. At First Quarter Mental Health, our goal is not simply symptom management—we are here to help individuals build confidence, resilience, and a strong foundation for lifelong well-being. Through collaborative care, thoughtful medication management, and genuine human connection, we strive to help every client reach their full potential. As a family-owned practice, we are committed to providing the same level of care, respect, and dedication to our clients that we would want for our own loved ones.
