Director of Operations

Henna Siddiqui

Henna was born and raised in Houston, Texas. She started her career in dentistry 10 years ago as a dental assistant and made her way to the administrative side due to her interest in patient education and knowledge in financial counseling. For her, the highlight of working in dentistry is the self confidence a healthy smile gives to patients and when she feels like she really made an impact on someone's life. In her spare time, Henna enjoys spending time with her family, reading and discovering new coffee shops.
