Welcome to Chandler Pediatrics!
We are delighted you chose to come in for a visit and I would like to introduce myself and share a bit about my background.
I am a native Arizonan, raised in Tempe. I was always interested in the medical field and became a hospital volunteer while in high school then ended up working part-time in the emergency room while attending Arizona State University. I had the opportunity to meet and work with many nurses and doctors which had a great influence on my career. I earned a nursing degree at Arizona State University and worked in an emergency room for 12 years.
I married my college sweetheart and we have five children. I continued to work as an ER nurse, but always knew I wanted an advanced degree, so when our children were 2, 4, 6, 8, and 10 years old respectively, I started my graduate degree. I completed a Masters in Nursing with a Certificate as a Family Nurse Practitioner. I began working in family practice but eventually ended up working in Pediatrics as I had always dreamed of. I enjoy working with kids and their families, especially love the ability to follow our patients as they grow, and supporting our families through the different stages of growth.
Outside of the clinic, I enjoy watching our kids sport activities, cooking, crafting, hiking and volunteering in our community, especially our church.
I am committed to building long- term relationships with our patients and their families founded on trust, compassion, education and open communication.
I feel humbled and honored to care for our patients and their families and thank you for choosing Chandler Pediatrics. I look forward to meeting you and support your child’s health and well-being.
Warmest regards,
Mary Margaret Rivera, FNP-BC

With 15 years of experience as a Pediatric Nurse Practitioner, I am passionate about providing compassionate, comprehensive care to children and families. My background is primarily in pediatric primary care, with additional experience in pediatric cardiology, gastroenterology, and pediatric dermatology. I practiced in pediatric dermatology for 1.5 years, and skin health remains a special clinical interest and personal passion of mine.
I also had the unique opportunity to live in London for two years, where I worked at Great Ormond Street Hospital, one of the world’s leading children’s hospitals. That experience broadened my perspective on pediatric medicine and deepened my commitment to family-centered care.
Outside of work, I enjoy spending time with my husband, our one-year-old son, and our Italian Greyhound, Lefty. In my free time, I love traveling, discovering interesting food, cooking, taking long walks, reading, and exploring local farmers markets whenever I can. I speak English and Spanish.
