Diana Muckler, MSN, PMHNP-BC

Hi, my name is Diana, and I'm a Board Certified Psychiatric Nurse Practitioner serving clients in Wisconsin. I specialize in anxiety, depression, ADHD, bipolar disorder, insomnia & sleep issues, obsessive compulsive disorder (OCD), life transitions, and post-traumatic stress disorder (PTSD) and trauma. I’ve been in nursing for over 10 years and completed my master’s and psychiatric training at Alverno College. I’m passionate about destigmatizing mental healthcare, and together with my colleagues at Lavender Psychiatry, I’m on a mission to create a world where feelings are felt, respected, and cared for.

My therapeutic style is characterized by compassionate, patient-centered care that recognizes the individuality of every person I treat. I combine evidence-based clinical practice with a warm, collaborative style, creating a safe environment where patients feel heard, respected, and empowered. My treatment philosophy emphasizes holistic assessment, thoughtful medication management, and …supportive psychotherapy tailored to each patient’s needs. I strive to build strong therapeutic relationships, promote resilience, and partner with patients in developing practical, sustainable strategies for mental well-being.

My practice is inclusive and welcoming, embracing diversity in culture, background, and experience. I have worked with a wide range of clients, including students, parents, professionals from various fields, skilled tradespeople, service industry workers, retail employees, entrepreneurs, artists, and technology experts. I am committed to providing a safe and supportive space where each individual feels heard, understood, and empowered to achieve their therapeutic goals. Starting treatment can be a scary and intimidating process. I’ve successfully treated many people who are new to psychiatric care.
