Dripping Springs Healthcare is an interdisciplinary holistic psychiatry practice formed as a collaboration between nurse practitioners and psychiatric physicians. The DSHC model blends holistic nursing care with medical science. DSHC believes in a strengths-based and systems-oriented approach to health and wellness. Life stress and illness rarely arise from a single factor, so positive change is rarely the result of a single treatment.  We believe that diet, exercise, lifestyle, thought patterns, stress tolerance, capacity for mindfulness, and medical interventions all play significant and interconnected roles in mental, physical, and spiritual health.
