Her scope of practice encompasses health promotion, disease prevention, diagnosis and management of common and complex health care problems. Before becoming a registered nurse, Diane worked as clinical research coordinator at UTMB where she explored and was exposed to research studies involving substance abuse, eating disorders and depression. Diane experienced great satisfaction in her work with patients as this is where her passion and love working with patients started. Diane has five years of working as a registered RN working in different areas of patient care such as orthopedic, trauma, neurology/neurosurgery and internal medicine. She is bilingual in English and Spanish, and holds two Bachelor’s degrees, (BS in Biological Sciences and a BS in Nursing); and in order to fulfill and address the needs in her work with patients, Diane completed a Master’s of Science in Nursing from the Family Nurse Practitioner Program in Texas Woman’s University.
