Dr. Abby Reineck currently serves as an outpatient child and adolescent psychiatrist. She has been practicing for 13 years. Dr. Reineck's practice primarily offers medication-management services in conjunction with either supportive or eclectic therapy. Follow-up appointments average 30 minutes, but may be more or less. Occasionally, Dr. Reineck believes the addition of a therapist is needed and will request you bring a therapist into your care team. This will be asked of individuals if she believes it will lead to an improved clinical outcome. Reineck received her medical degree from Boonshoft School of Medicine at Wright State University, located in Dayton, OH. She completed her psychiatry residency and child and adolescent fellowship at Dartmouth-Hitchcock Medical Center, in Hanover, NH. After completing her training, Dr. Reineck moved to Brattleboro, VT, where she became an attending psychiatrist at The Brattleboro Retreat, working on both the child and adolescent inpatient units. The Brattleboro Retreat's location was such that it served a large number of patients from nearby states, which included New Hampshire, Massachusetts, Connecticut, and New York. However, it also served as the only psychiatric inpatient facility for children and adolescents in the entire state of Vermont. Dr. Reineck also worked as the lead psychiatrist on the inpatient, adult, dual-diagnosis unit. This unit provided care for individuals struggling with addiction and mental-health related issues, some of whom required medically supervised detoxification. After roughly five years, Dr. Reineck moved from Vermont to Erie, PA. She began working at a residential treatment facility for child and adolescent patients who required care in a highly supervised and highly structured setting. Dr. Reineck also began serving as a child and adolescent psychiatrist for patients enrolled in a school-based partial-hospitalization program. Dr. Reineck gradually transitioned from these roles into strictly outpatient work. She worked as an outpatient psychiatrist in Butler, PA, where she treated child, adolescent, and adult patients. Dr. Reineck eventually narrowed her scope of practice to providing psychiatric treatment for only outpatient children and adolescents. She did so out of facilities located in Erie and Meadville, PA. Drr. Reineck completed her undergraduate studies at Ohio University. While Dr. Reineck has experience treating a wide variety of patients, her primary focus has been treating children and adolescents with a vast array of presenting concerns.
