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.
