While attending New York University College of Dentistry, Justin was elected as student council president and served on many associations or committees. After completing education at NYUCD, he matched with the University of Texas Houston for his oral surgery and medical school training. During that six-year residency, many opportunities were afforded to work with world-class physicians and surgeons, true giants in their own specialties.

After graduation, he went on to become board certified by the American Board of Oral and Maxillofacial Surgery. Since graduation, Justin has worked in several different offices, including ClearChoice, which afforded him a special subset of skills adapted to handle complex oral reconstruction with dental implants. He also served as a part-time assistant professor at Memorial Hermann TMC, which is consistently ranked as one of the busiest trauma centers in the US. 

His belief system is very simple yet all-encompassing: treat each patient as if they are your own family member. This has truly allowed him to create lasting connections with his patients, who are like extended family.

Outside the office, Justin loves to volunteer his time at a local faith-based clinic treating the underserved population in Houston. When he is not busy with oral surgery, he loves to spend time with family and friends and take part in outdoor activities like paddle boarding and fishing. Justin, Angela, and Vincente are dog lovers and have three dogs at home that hold the titles of CEOs of Happiness.
