Ivonne Sahagun-Carreon MD
President, River Valley Pediatrics MD PA Board Certified by the Fellow American Academy of Pediatrics F.A.A.P
Dr. Ivonne Sahagun-Carreon—known to most simply as “Dr. C”—is the heartbeat and backbone of River Valley Pediatrics. With nearly three decades of experience in pediatric medicine, she brings unmatched clinical expertise, deep compassion, and the kind of wisdom that only comes from truly being in the trenches. A graduate of Baylor College of Medicine, Dr. C trained at Texas Children’s Hospital under the mentorship of the legendary Dr. Ralph Feigin, one of the most respected names in pediatrics. That world-class foundation continues to fuel the exceptional care she provides every day. For more than 20 years, she has served New Braunfels and the surrounding areas—earning the trust of generations of families. Whether she’s treating a newborn, managing complex chronic conditions, guiding a teen through mental health struggles, or mentoring the next generation of providers, Dr. C shows up with one mission: to serve with excellence and heart. At River Valley Pediatrics—a privately owned practice built on hard work, trust, and family values—Dr. C leads by example. Her vision, grit, and unwavering dedication continue to shape not just this practice, but the future of pediatric care in Central Texas.
"There’s no substitute for experience, no shortcut for trust. I’ve spent my life earning both—and I’m still learning every day." - Dr. C

River Valley Pediatrics Staff
Our Support Team
Behind every check-up, phone call, chart update, and smiling face at River Valley Pediatrics is a team that’s been through the fire—and came out stronger. We’ve seen what it means to adapt, evolve, and rebuild. Like many businesses, we faced challenges during and after the pandemic. Staff turnover, changing expectations, and operational growing pains hit hard. But instead of making excuses, we made changes. RVP has doubled down on quality—from top to bottom. We listened to feedback (even the hard stuff), studied our reviews, revamped our workflows, upgraded our systems, and committed to fast, responsive, high-quality care for every family who walks through our doors. The result? A fully stacked, highly trained, and ridiculously dedicated support team that knows how to move. No calls left unanswered. No messages left hanging. Less wait time. More face time. Efficient, compassionate care—every time.
This isn’t just a staff list. This is the team that stood up, showed up, and helped bring River Valley Pediatrics into a whole new chapter. And we’re just getting started!
