I have been a patient of Dr. Yvonne Villarreal for the past five+ years, and have the greatest respect and trust in her abilities to track down causes of puzzling and complicated health problems, and to suggest rational and often more natural approaches through other modalities along with her excellent allopathic treatments. Doc V (as she is called) has made her office unique with an environment that respects a quiet, environmentally healthy experience for all her patients.
