At the heart of my practice is the belief that patients deserve to be heard.

I provide psychiatric evaluations, medication management, supportive therapy and evidence-based interventions for conditions including anxiety, depression, ADHD, mood disorders, trauma related concerns and life stressors. I have ten years of experience working in the mental health field in inpatient, outpatient residential, long-term care, tele-health and community mental health settings.
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).

No single approach fits all clients; I tailor my approach to each client, making it relevant to the specific problem they are facing. The best way to understand your current issues is to examine how your past influences who you are today. I also emphasize understanding your emotions and past patterns to ensure a better understanding of yourself. I strive to provide a gentle and warm experience, ensuring you are comfortable within the therapy setting and process these hard feelings through a genuine relationship. I also ensure that you understand the process of our work together so you can feel informed and empowered.
I have extensive experience in community mental health and private practice settings working with teens and adults. I received my Masters of Science in Psychology from Johnson & Wales University. I am licensed to practice in Rhode Island, Connecticut and Massachusetts.
For 18 years, I worked in education as an elementary school teacher, school therapist, and Director of Counseling, giving me a unique perspective on the challenges teens and families face. In private practice, I work with adolescents (13+), adults, and older adults, helping them navigate stress, anxiety, depression, life transitions, and relationship struggles. My clients often say they appreciate my direct, motivating, and real approach, which helps them feel like an equal in the therapy process.


Headway helps you manage obsessive-compulsive disorder with expert-guided support — from finding the right therapist or psychiatrist, to understanding costs, to scheduling with ease.
Finding the right OCD therapist in Westport starts with looking for a provider who has specific training in obsessive-compulsive disorder. Some providers use specialized approaches — particularly exposure and response prevention (ERP) and cognitive behavioral therapy (CBT) — so a provider's experience with these methods may be worth considering as you explore care options with a qualified professional. Consider whether you prefer in-person sessions in the Westport or broader Fairfield County area, or whether virtual appointments fit your schedule better.
Therapy in Westport and surrounding towns in Connecticut can be expensive, especially for specialized care. Using your in-network insurance benefits is one of the most direct ways to reduce what you pay per session. On Headway, you can enter your insurance details to see estimated costs before you book, and many patients pay as low as $0 per visit. Nationally, Headway partners with over 100 insurance plans, making it easier to find an OCD specialist who fits both your clinical needs and your budget.
Reading a provider's bio before booking can help you understand their approach, the populations they work with, and whether they feel like a good match. Many providers on Headway also offer a free phone consultation, so you can ask questions about their experience with OCD and get a sense of their style before committing to a full session.
