Meet Our Team

Kata Barragan
Clinical Support Orthodontist

Kata Barragan is a highly valued member of our clinical support team, bringing extensive international training and experience to her role in assisting Dr. Miller with comprehensive patient care. A licensed dentist and orthodontist from the National University of Colombia, Kata has been an integral part of our practice for the past 12 years.

In her role, Kata collaborates closely with our team, applying her strong clinical background to support patient communication, education, and treatment planning. She is known for clearly explaining procedures and emphasizing the importance of proper oral care, helping patients feel comfortable and informed throughout their treatment.

Kata’s advanced skills in orthodontics stem from her years of experience working with diverse patient populations in Colombia. Her expertise continues to elevate the level of care we provide.

Outside the office, Kata is deeply devoted to her growing family - her husband, their 2-year-old daughter, and a new baby girl on the way. She enjoys reading, traveling, and dancing, and as a former ballet dancer, she loves attending ballet performances whenever she can. Now rooted in this community, Kata is committed to building meaningful connections and contributing to the positive impact our practice makes each day
