Denise Coscia, PhD
Denise Coscia, PhD., received her doctoral degree with Psi Chi honors at Hofstra University in 2007. Hofstra’s doctoral training program is cognitive-behavioral and therefore has prepared Dr. Coscia well for helping our patients to understand their strengths and weakness in cognitive behavioral terms.
Her time at North Shore LIJ, provided a wide range of experience with psychological testing, evaluation and research, as well expertise in doing cognitive-behavioral assessments and diagnosis, and is therefore a major asset here at Suffolk Cognitive Behavioral. She had previously gained additional CBT expertise at The Bleuler Psychotherapy Group where she worked with a diverse range of, children, adolescents and adults presenting a full range of problems, e.g., from ADHD, to mood disorders to anxiety, phobias, and relationship problems. She has also developed CBT skills working individuals with more severe problems due to her valuable time interning at Brunswick Hospital Inpatient Psychiatric Unit and volunteering at Payne Whitney Cornell Medical Center. Further broadening her range of skills, she interned at both the elementary and high school levels , giving her the opportunity to develop insight and skills for helping the developing adolescent. Dr. Coscia’s experience working with aging populations and geriatrics has provided extensive experience and empathy for the challenges of growing older, something more and more American baby boomers are going to have to face and learn to thrive in. This full range of developmental experience has also provided Dr. Coscia with an understanding of adult family dynamics and the challenges of adults caring for aging parents and children.
All in all, we are very proud of the full range of life experience and CBT background Dr. Denise Coscia brings to Suffolk Cognitive Behavioral, as well as the deep care and empathy she has cultivated while working with both the challenges of adolescence, emerging adulthood, middle age, as well aging adults.
