The sugar bug battleground is Dr Alegra’s favorite Super Place. She can often be found taking a few extra moments to share with families how to prevent cavities. She has a passion for helping kids stay healthy and happy. She began to learn her super powers at the early age of 15 when she assisted a dentist near Philadelphia, Pennsylvania who loved his patients and showed her the art of dentistry. She started her advanced power training with a full scholarship to dental hygiene school. Since then she has earned 3 degrees including her doctorate from Temple Dental School and 2 certificates. Her final certificate was received from the University of Minnesota as a pediatric dentist. She has been honored multiple times, receiving awards for dental health education and as the Most Outstanding Female Dentist in her dental class. Her favorite achievement, capturing the heart of her husband, “The Closer” Abe, makes her even more energized as he is always devising new schemes to combat those crazy sugar bugs. Together they hope to empower kids throughout the Valley to make it Cape Time and defeat sugar bugs every day.
