About Diane

Hi, I'm Diane Witkowski, PMHNP-BC. I believe that compassionate, evidence-based mental health care can make a meaningful difference in every stage of life. My goal is to provide a welcoming, supportive, and judgment-free environment where children, adolescents, and adults feel comfortable discussing their concerns and actively participating in their treatment journey.

I began my nursing career more than 15 years ago as a Registered Nurse at Children's Hospital, where I developed a strong foundation in patient-centered care. Throughout my career, I have also served as an auditor and quality improvement specialist, helping to improve the quality and delivery of care for individuals receiving home-based services. These experiences strengthened my commitment to clinical excellence, patient safety, and high-quality behavioral health care.

I later earned my Master of Science in Nursing with a specialization in Psychiatric Mental Health Nurse Practitioner. My clinical experience includes emergency medicine, wellness medicine, and psychiatry, providing me with a broad perspective on the connection between physical health, emotional well-being, and overall quality of life.

I provide comprehensive psychiatric evaluations, medication management, and supportive psychotherapy for children, adolescents, and adults experiencing conditions such as anxiety, depression, ADHD, bipolar disorder, trauma-related disorders, schizophrenia, and other behavioral health concerns. My treatment philosophy combines evidence-based practice with clinical expertise, thoughtful observation, and individualized care tailored to each person's unique needs.

My training in trauma-informed care and experience working with individuals from diverse cultural backgrounds have reinforced my passion for increasing access to compassionate, affordable, and equitable mental health services. I believe that every individual deserves to be treated with dignity, respect, and empathy while working toward lasting emotional wellness.

Outside of the clinic, I enjoy spending time walking my dog, listening to motivational podcasts, and, whenever I get the chance, enjoying my daughter's homemade chocolate chip cookies. I look forward to partnering with you on your journey toward healing, resilience, and improved mental well-being.
