Dr. Cynthia Rivas is an endocrinologist who approaches her patients' health concerns with empathy and understanding.
"I take time to understand their perspective while addressing their medical conditions and concerns," she said. "I also involve them in the decision making. This helps them feel empowered to take control of their health."
Dr. Rivas chose medicine as a career path because she wanted to help people prevent and manage both chronic and acute medical conditions. She has always been fascinated with endocrinology specifically because of the difference she can make in a patient's quality of life.
"Most of my patients' conditions are caused by hormone or metabolic imbalances, and with the right approach, we are able to treat them and improve their overall health and well-being," she said.
One piece of advice Dr. Rivas has for patients is to take a balanced approach to exercise and diet.
"Focus on activity that aligns with your fitness levels and goals, and choose healthier food options when you're able and avoid ultra-processed foods," she said.
Dr. Rivas is originally from Marcay, Venezuela. She earned her medical degree from Universidad Autonoma de Guadalajara in Mexico. She completed an internal medicine residency in South Texas and moved to Tucson for a fellowship.
While in Tucson, she fell in love with the desert and its people, and now calls the Old Pueblo home. When she's not working, Dr. Rivas enjoys practicing yoga and Pilates, travel and trying different foods.
