MassachusettsHolly James Corrigan, RN, MSN, PMHNP, is a board-certified psychiatric nurse practitioner committed to helping people navigate their mental health with skill and heart. She earned her BSN from Russell Sage College in 2009, her MSN from Massachusetts General Hospital Institute for Health Professions in 2016, and completed Psychiatry Redefined’s Fellowship in Functional and Integrated Psychiatry in 2025. Holly keeps current by attending top conferences, like the International Trauma Conference in Boston, ensuring she’s always at the forefront of her field.

Holly’s philosophy is simple yet powerful: care should fit the person, not just the diagnosis. She’s passionate about tackling complex issues—suicide prevention, C-PTSD, chronic depression, ASD, OCD—and advocating for underserved communities. For Holly, it’s about delivering real, meaningful support to those who need it most.

Her career began as a registered nurse in neurology, pediatrics, and emergency care, before she found her calling in psychiatry. Since then, she’s provided medication management and supportive psychotherapy in outpatient clinics and worked in inpatient units serving adults and adolescents.

Holly believes in patient-centered care based on the individual, rather than focusing only on a diagnostic algorithm. The first appointment will include a comprehensive psychiatric evaluation and a discussion about what your goals of treatment are. Pharmacological and therapeutic recommendations are both important elements of the treatment plan. Follow up appointments will be more concise, but may include various therapeutic modalities, medication changes, and supportive psychotherapy.

Dr. Karina Fatova is a board certified psychiatrist who hails from New York City but has made New Orleans her home for the past ten years. She is a graduate of Albert Einstein College of Medicine in Bronx, NY, and she did her adult psychiatry residency at Tulane University in New Orleans, LA. She was proud to have her first position post-residency at the River Oaks Hospital Trauma Unit in New Orleans, LA where she treated patients with Complex PTSD and eating disorders. The Trauma Unit was one of a few of its kind nationally because it provided very specialized treatment that was affordable to many. Dr. Fatova then went on to work at the New Orleans Veterans Affairs Hospital for the last five years in its ambulatory outpatient mental health clinic. Though her passion is Complex Trauma/PTSD, she also regularly saw veteran patients who have been diagnosed with anxiety, depression, bipolar disorder, ADHD, and adjustment disorder. During her five years at the New Orleans VA, she received three special commendations from the director of the VA for feedback from her patients about her effective integrative approach to supportive psychotherapy and medication management. She believes that her rapport with her patients, and their therapeutic work together, is just as important as the medication she prescribes to heal or alleviate their symptoms. Dr Fatova employs psychodynamic therapy techniques, at times, to help those patients who would like to explore childhood experiences that may continue to impact them in their adult lives. With respect to medication management she regularly helps patients target symptoms such as sleep issues, nightmares, persistent worry, emotional dysregulation, frequent mood changes, impulsivity, and "toning down the nervous system," among others. She strongly believes that treatment decisions are best approached as a collaboration between patient and doctor. She sees young adults who are just starting their journey into adulthood, as well as adults who have been navigating life with challenges, which may include untreated, or poorly treated, mental health symptoms. Often, by the time Dr. Fatova sees a patient, they may have lost a significant amount of faith in their mental health doctors, and she is particularly attuned to helping individuals with this type of experience.
