Meet the Team Behind Essential Medical Beauty Treatments
At our Brownsville practice, medical know-how, advanced aesthetic technology and real personal attention come together. Meet the team that guides you through every step of your treatment.

Francisco Javier del Castillo, MD, FACOG — Medical Director

Dr. del Castillo entered this profession because he values helping patients improve through a range of treatments that genuinely work. He finds satisfaction in solving patients' problems and makes time to talk with each person, building a full picture of the health concern and how it affects their life. His aim is to provide high-quality, compassionate care to every patient, because each one is special.
He is skilled at treating female conditions from adolescence through post-menopause and is experienced in gynecologic surgery, offering both traditional and minimally invasive options for concerns such as urinary incontinence and pelvic floor relaxation. Taking a whole-person view rather than focusing only on disease, he also provides acupuncture alongside traditional Western medicine to help manage a range of issues related to pain, stress and obesity.
Having seen the toll excess weight takes on many of his patients, he now offers a highly effective, outcome-focused medical weight loss program for people who know firsthand the difficulties and complications of carrying extra weight.
Dr. del Castillo is medical director of Essential Medical Beauty Treatments, which brings the latest medical technology breakthroughs to appearance enhancement. Services include:
- Vectus® laser hair removal treatments
