About Us
Who We Are
DM Integrated Health Partners is a psychiatric mental health practice dedicated to expanding access to specialized care for individuals and families across Texas — with a special focus on rural South Texas and Bexar County. Founded by two doctorally prepared Psychiatric Mental Health Nurse Practitioners (PMHNP-BCs).
Our motto, “Dedicated to Mind and Medicine,” reflects our belief that effective psychiatric care must honor both the person and the science. Mind represents respect for each patient’s story, culture, and values; Medicine stands for using evidence-based practice, clinical expertise, and careful follow-up to ensure safe, effective treatment.
In everyday practice, appointments are unhurried, collaborative, and rooted in open communication rather than quick fixes. Patients can expect thorough evaluations, transparent discussion of options, and shared decision-making that prioritizes their goals and well-being.
With deep roots in the communities we serve — and as a proud military veteran and lifelong Texans — we are committed to bringing high-quality, compassionate psychiatric care back to the areas that shaped us. At DM Integrated Health Partners, our mission is to make sure that geography, background, or circumstance never stand in the way of quality mental health care.
