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.

Dr. Kotadia is a board-certified psychiatrist who completed his psychiatry residency training program at Nassau University Medical Center in Long Island, NY. After completing training, he has been practicing outpatient psychiatry and specializes in the evaluation and management of major psychiatric disorders, including depression, and anxiety. He uniquely combines his education, training, and practical experiences into specialized treatment plans. Typically, he offers this in conjunction with supportive or emotionally focused therapy in 30-minute follow-up visits. However, occasionally Dr. Kotadia may believe that additional therapy is also needed and ask that you bring a therapist into your care team to provide the best outcome. A story that Dr. Kotadia came across years back still inspires him each day. A man was taking a morning walk at the beach. He saw that along with the morning tide, came hundreds of starfish. When the tide receded, the starfish were left behind and would die in the morning sun. While the tide was fresh, and the starfish were alive, the man took a few steps, picked one up and threw it into the water and continued throwing starfish back into the ocean. Behind him was a stranger who couldn't understand what this man was doing. He caught up with him and asked, "What are you doing? There are hundreds of starfish. How many can you help? What difference does it make?” The man did not reply, rather he took two more steps, picked up another one, threw it into the water, and said, "It makes a difference to this one.”With this story as his motivation and ultimate objective, it has always been Dr. Kotadia's goal, with each patient, to provide superior services.
