Experts in Pediatric Urologic Care

About Our Practice

Pediatric Urology of San Antonio provides expert, compassionate care for children and adolescents with urologic conditions across Central and South Texas. With clinics in both San Antonio and New Braunfels, our team offers a full range of services—from early evaluation and diagnosis to advanced surgical treatment. We care for patients from infancy through adolescence, and in many cases, continue care into young adulthood. Whether managing a routine concern or a complex condition, our approach is always thoughtful, collaborative, and personalized to each patient’s needs.

  • Timely access to appointments, including same-week consults for urgent needs
  • In-house diagnostic services including renal ultrasound, urodynamic testing, and cystoscopy
  • Comprehensive evaluation and individualized treatment plans
  • Minimally invasive, laparoscopic, and robotic surgical options when appropriate
  • Ongoing communication with referring providers and caregivers

Whether your child needs a quick office procedure or surgery at a local hospital or surgery center, we make every effort to keep care centralized and coordinated. We aim to minimize the stress often associated with medical visits while ensuring that each child receives care tailored to their specific condition and stage of development.

A Trusted Partner in Pediatric Urologic Care

Experienced, Fellowship-Trained Pediatric Urologists

Our team of board-certified and fellowship-trained pediatric urologists has years of experience managing conditions that impact the kidneys, bladder, genitalia, and urinary tract. Whether your child is experiencing urinary tract infections, urinary incontinence, or requires evaluation for a condition like hydronephrosis, vesico-ureteral reflux, hypospadias or undescended testicles, our providers are equipped with the training and clinical insight to offer the highest standard of care. Our team performs open, endoscopic, and minimally invasive procedures, including laparoscopic and robot-assisted surgeries using the Da Vinci system. We also provide prenatal consultations for expectant families when fetal urologic anomalies are detected, ensuring continuity of care from diagnosis through treatment.

Our physicians have held leadership and academic appointments at major children’s hospitals and regularly contribute to research and clinical education.  We follow best practices outlined by the American Urological Association’s pediatric guidelines to ensure our clinical protocols are evidence-based and aligned with national standards. Their work has been published in peer-reviewed journals, presented at international conferences, and featured in medical textbooks, reflecting a commitment not only to patient care but also to advancing the field of pediatric urologic care. Our providers are also fluent in multiple languages, including Spanish, Portuguese, and French, allowing us to serve a diverse patient population with clarity and cultural sensitivity.
