Chief Clinical Officer - Dentist

Dr. Christine Coughlin

Dr. Christine Coughlin is from Los Angeles, where she attended the all-girls Catholic college-preparatory school, Marymount High School, a historical monument established in 1923, known for a rich history in empowering young women to become ethical leaders who dedicate their lives to service. During her time at Marymount, Dr. Christine participated in many amazing community outreach opportunities, where she discovered a deep passion for making a difference in the world by loving and serving others.

…a deep passion for making a difference in the world by loving and serving others…

Dr. Christine always had many passions and interests. She excelled in Art and received the Art Studies Award from the Bank of America Foundation. She played the piano from age four and competed up to age 17. Dr. Christine also played point guard as captain for Marymount’s Basketball team. She always invested in her teammates and encouraged them to play their hearts out together.

Dr. Christine graduated Magna Cum Laude from Marymount and went on to Westmont Liberal Arts College in Santa Barbara on a scholastic scholarship and was on the Dean’s List every semester. She graduated with honors Pre-Dental Cum Laude with a Bachelor of Science in English and a background in Studio Art.

That summer, Dr. Christine went on a mission trip with International Service Learning, a global volunteer program, where she helped raise funds and provide essential Medical and Dental care to the underserved villages of Nicaragua and Costa Rica. She fell in love with the precious villagers, who were full of joy and gratitude for the little our team was able to offer for such a great need.

This powerful experience touched her heart deeply, and she found her purpose: to give love and hope to others. And she knew Dentistry was the right path for her.

Dr. Christine went on to the University of Southern California School of Dentistry, where she met her husband, Nathan, and they have been inseparable since. They both received their Doctor of Dental Surgery degrees, got married, and got their first home and puppy (Sophie). Dr. Nathan continued his studies in the Orthodontic Specialty at USC. After he graduated, the two moved to Dallas to follow their dream of opening a Dental & Orthodontics practice together. Dr. Christine loves pouring into her team and her patients and wants more than anything to help them thrive.

During her free time, Dr. Christine loves spending time with the ladies of the Dallas Beloved Women’s Ministry, which serves previously incarcerated women, playing Pickleball with her husband and The Dinkers (their Pickleball group), and cooking healthy meals for her family while hanging out with their sweet golden retrievers, Lola & Sophie.
