This commitment to lifelong learning and a patient-centered approach equips Dr. de Palma with the knowledge, skills, and mindset needed to deliver personalized, comprehensive care that enhances her patients’ oral health and overall well-being.
Beyond her professional achievements, Dr. Claudia de Palma is deeply committed to humanitarian efforts, particularly in refugee advocacy. She played a pivotal role as the Refugee Sponsorship Coordinator for the Diocese of St. Catharines, passionately supporting the reunification of families and helping them build brighter futures. Her unwavering dedication extends to her role on the Board of Directors at CASA EL NORTE, a transitional home for refugees.
Dr. Claudia de Palma is also a proud volunteer with Health Outreach, a not-for-profit charitable organization dedicated to providing health services, including public health, to impoverished people in remote areas of developing countries. Every year, she travels with the organization to Guatemala, where she provides much-needed dental care to remote communities, striving to enhance lives through her work.
In addition to her volunteer work, Dr. de Palma is actively involved in the local dental community. She has been serving on the Executive Board of Directors of the Niagara Peninsula Dental Association since 2020, contributing to the advancement of the profession.
Currently residing in Fonthill, Dr. de Palma cherishes spending time with her husband, Alex, their three children Jose, Sammy, Isabella and the family’s australian Labradoodle “Coco” . Outside of her practice, she finds joy in the outdoors, creating lasting memories with family and friends.
