We believe in a team approach to your child’s health and well-being. Your child’s physician, along with the entire staff of LPPG, collaborates with each family to provide excellent pediatric care, education and support to every child.
Our five physicians (each is a partner in the practice) and two nurse practitioners are supported by a full team of kid-loving RNs and two medical technicians. The doctors hand-picked each staff member, not only for their extensive pediatric skills, but for their desire to help parents raise happy, healthy children. Rounding out this team is the clerical and administrative staff which stands ready to assist each and every patient family.
Each of our skilled and passionate providers has dedicated their career to child-focused health care. We hope you find these brief biographies helpful in getting to know them.
