I am a Psychiatric Nurse Practitioner (PMHNP) who believes that true and lasting healing happens when we treat the whole person—mind, body, and spirit—not just symptoms. I approach each patient with compassion, curiosity, and deep respect, ensuring you feel empowered to explore your healing journey in a safe and supportive space.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over a decade of experience in mental health care, supporting individuals across inpatient and outpatient settings. Through my work, I have cared for clients with a wide range of needs, including chronic and severe mental health conditions, and I understand how overwhelming it can feel to navigate symptoms while trying to maintain daily life.

My care philosophy is centered on partnership. Treatment is not about taking over your care, but about working with you to explore your symptoms, goals, and values. Together, we develop a treatment plan that feels respectful, personalized, and empowering. If you have concerns or hesitations about medication, we will discuss all available options openly and thoughtfully, moving at a pace that feels right for you.

I work with individuals experiencing depression, anxiety, trauma, ADHD, bipolar disorder, schizophrenia, OCD, and other mood and thought-related conditions. During the initial session, we focus on understanding your concerns, reviewing your history, and identifying practical steps toward improvement. Care may include psychiatric evaluation, medication management when appropriate, brief psychotherapy, education, and ongoing support.

I believe mental health care should feel supportive, clear, and collaborative—not rushed or overwhelming.

You do not have to face these challenges alone. My role is to help you reduce symptoms, strengthen coping skills, and regain balance so you can function at your best and move forward with confidence and stability.

Diana Lankenau has a Master of Science in Nursing from Florida State University and Chamberlain University. She has a Bachelor's in nursing from University of Miami. BA in Psychology from Florida International University. She is Board Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-BC).

My practice centers on helping people work through depression, ADHD, and bipolar disorder with care that actually fits their life. I've been in independent practice for about two years, and in that time I've found that the providers people stay with are the ones who listen well and adjust as things change. I'm a PMHNP with full practice authority, so I can manage medications and provide psychiatric services without a collaborating physician. I see clients via telehealth throughout Illinois, with flexible scheduling available Monday through Saturday. If you've been waiting to find someone who's approachable and genuinely wants to get you moving in the right direction, I'd like to be that person.
