Derrick at City Smiles


Treatment Coordinator

Becky has more than 20 years of dental experience and even grew up in a dental office.  She is extensively trained in all areas of dentistry and has received several advanced degrees and certifications for dental assistants.  She will be there with you through any procedure to comfort you and ensure you are always receiving exceptional care.  Becky is one of Dr. Hill’s extra hands, someone he closely relies on and she always brings joy (and some sarcasm) to our day and yours!

Becky enjoys traveling internationally and experiencing different cultures.  When she is home you can catch her spending time with her boyfriend, hanging out with family/friends, and snuggling with her dog Pickles.  She loves to read, play cards, scrapbook, and do crafts.  Becky is also petrified of cotton balls.  (Thankfully, we don’t use those here!)
