Dr. Helena Cho

After finishing her bachelor's degree at Bryn Mawr College, she continued towards her Doctor of Dental Medicine degree from Temple University Kornberg School of Dentistry.

Today, she most enjoys treating oral caries and disease, while also restoring smiles that help patients regain their confidence! As a general dentist, Dr. Cho loves the opportunity to provide oral care for everyone - from six-month-old patients visiting the dentist for the first time to 91 years old grandparents who need a check-up, Dr. Cho wants to ensure your family's dental care is her top priority! Along with her husband and two young children (who keep her busy outside the office!), Dr. Cho is very excited to join and serve the dental needs of the local community. In her free time, Dr. Cho likes to explore local parks and playgrounds with her kids. She is also very excited to try new restaurants in North Dallas because it has so much to offer!
