Marsh Landing Behavioral Group evolved from Dr. Mark Tomaski's solo child psychiatry practice on Third Street South in Jacksonville Beach. Dr.Tomaski opened this practice in 1996 while practicing as the first child psychiatrist at Nemours Clinic, and consulting for Wolfsons Children's Hospital Psychiatry Unit and Jacksonville's community mental health care system. With recognition that Northeast Florida offered only fragmented mental health care, he began developing a private group practice to provide comprehensive care to children and families. Marsh Landing Behavioral Group is now an established multidisciplinary practice integrating classic treatment concepts and the modern neurosciences.

Marsh Landing Behavioral Group offers medical and behavioral therapy to children and families coping with a myriad of problems. Specialists in our group provide adult psychiatry, child psychiatry, clinical psychology, and family counseling.
