Meet the Doctors

Dr. Gretchen Hoover

Dr. Gretchen Hoover loves being a dentist and gets the most joy out of having her patients go from being afraid of the dentist to looking forward to their next dental appointment.

Pain-free dentistry is something she is always working to achieve, and her patients would definitely agree. Dr. Hoover holds herself to a high standard of excellence and believes in surrounding herself with a wonderful, well-trained team that helps her be the best Dentist possible for her patients. Creating a positive energy when you walk through the doors is paramount with Dr. Hoover. Being the Best Dentist in Austin and providing the best care available to everyone she sees is Dr. Hoover’s goal, and one all of her patients would say she has already achieved.

Personally, Dr. Hoover and her husband Dale have two beautiful daughters, Brodie and Tatum, as well as a handome energetic son-Cort.  They love spending time together with their two dogs, and love staying active and traveling.

Dr. Hoover attended the University of Texas in Austin, where she received her bachelor’s degree. She then returned to Houston where she completed her master’s degree at the University of Houston Clear Lake. She completed her Dental school training at the University of Texas Dental Branch in the Houston Medical Center. Dr. Hoover graduated from the University of Texas Dental Branch at Houston, where she was President of her class. She received the coveted Student of the Year Award and Senior Dental Student Award.

We want our Dental practice to be one that we would want to go to. So we all work very hard together every day to make sure that it truly is.

Dale Hoover

Mr. Hoover is the Business Manager as well as the Marketing Director for About Smiles. He has been an integral part of helping About Smiles grow as a company over the past 12 years. He is also Dr. Gretchen Hoovers husband.

Dr. Hoover and Dale started with just one office in South Austin 12 years ago, and through the implementation of strategic marketing and proper business management, as well as excellent patient care, have been able to grow to two offices proudly serving the greater Austin and Round Rock areas.

Together they believe that by treating the patients who trust About Smiles with their dental needs, exactly the way that they would want be treated is the key factor in the success of About Smiles.

Dr. Sarah Herman

Dr. Herman grew up in California and has gone to school up and down the coast. She completed her undergraduate studies at University of California at San Diego and her dental training at the University of the Pacific Arthur A. Dugoni School of Dentistry in San Francisco. After dental school, she completed a General Practice Residency with the VA in Sacramento for additional training in oral surgery, periodontal surgery and implants.

Dr. Herman is passionate about dentistry and patient care. She treats patients like family and strives to ensure her patients are comfortable throughout their appointments while receiving excellent clinical care.

When she's not at the office, Dr. Herman loves spending time with her family. She and her husband Matt, a local orthodontist, spend most weekends wrangling their two little girls Olivia and Nora. Dr. Herman grew up surfing in California, but is more likely to throw her back out with elaborate gardening projects these days. She still loves to ski and always has her nose in a book.


Dr. Smita Rewari

Dr. Smita Rewari graduated from Texas A&M School of Dentistry in 2008. Her main focus during her career has always been to provide the highest level of patient care and to be on the cutting edge of dental technology and research so her patients can benefit from that. She has a high comfort level with all aspects of dentistry and truly enjoys building relationships through her work as a dentist. Growing up in another country and experiencing dental issues herself made her empathetic to patients who are nervous or fear certain aspects of dental care and she prides herself on being able to help these patients by demystifying dentistry and creating a calm and pain free environment for procedures. She is also certified to provide Nitrous and Oral Sedation and is happy to discuss these options with patients that are interested. In her free time, she enjoys hanging out with her husband and two daughters as they experience all the great food and culture Austin has to offer. She also enjoys reading, writing, performing in community theatre and is passionate about staying active and eating well.
