Krystle Fiengo

Hi, I’m Krystle Fiengo, PMHNP-BC, a Board-Certified Psychiatric Mental Health Nurse Practitioner with over 15 years of experience in healthcare. My path into psychiatry has been both professional and personal. I started as a pharmacy technician, drawn to how medications could support healing. Over time, I realized I wanted to care for the whole person—mind, heart, body, and soul. That desire led me to become a nurse and, eventually, a psychiatric nurse practitioner. I’ve worked in a wide range of settings, including pharmacies, acute rehab, hospitals, inpatient psychiatric units, a neuroscience research unit, and community mental health. These experiences gave me a deep and well-rounded understanding of mental health care and the many factors that shape well-being. Along the way, I’ve been mentored by amazing professionals—a Yale psychiatrist and professor, a physician with expertise in addiction medicine, and several experienced pharmacists—whose guidance continues to shape my clinical values and approach. I specialize in treating anxiety, depression, bipolar disorder, and trauma-related conditions. I use a trauma-informed, person-centered lens to create a safe, respectful, and empowering space where individuals feel heard, supported, and not judged. I believe healing begins with connection, and I approach every session with empathy, curiosity, and care. My own lived experiences have given me a deeper understanding of what it means to struggle and reach for help. I carry that insight into every interaction and stay grounded in compassion. I’m a strong advocate for my patients and believe in informed choice, open communication, and shared decision-making. Together, we’ll explore what wellness looks like for you and work toward it—at your pace, honoring your goals and values.
