Thompson Health Canandaigua Medical Group

Pediatricians provide preventive health maintenance for healthy children and medical care for those children who are seriously or chronically ill. From immunizations to monitoring growth and development, from counseling on age-appropriate nutrition to guiding children and families through the potentially tumultuous phases of puberty and adolescence, prevention and health maintenance underscore every patient care interaction. Pediatricians work with other medical specialists and midlevel professionals to provide for the health and emotional needs of children.

Pediatricians are concerned with more than just the child’s physical well-being. They are increasingly involved with the prevention, early detection, and management of behavioral, developmental, and functional social problems that affect children and adolescents. Their skilled assessments may uncover depression or anxiety in children, particularly those who are technology-dependent, or whose activity is limited by chronic conditions. With structured evaluation and early intervention, the primary care pediatrician identifies and addresses the developmental and behavioral issues that result from exposure to prevalent psychosocial stressors.
