Mariola Widuch, DMD


Mariola Widuch Centercare staff


Centercare has been serving patients downtown and in the historic districts for twenty-five years and Mariola has been part of that for twenty-one of those years. She is the omnipresent glue that connects all parts of the practice.  For supplies, insurance, software, clinical procedures, patient histories and all the details that make a dental practice go, Mariola is the final resource for everyone around her.
Mariola is a dentist, trained at the Medical Academy of Gdansk in Poland.  Within a month of completing her studies there, she was on a plane for Chicago to marry her American sweetheart, Mark. They came to Mesa and have a family of two boys, now 14 and 18.
Under Arizona law, Mariola would have to get additional training, out of state, to fully license to practice dentistry here. That hasn’t been feasible for her yet, but at Centercare we benefit from her knowledge and skills.



Raquel Barron


Centercare Arizona Raquel Barron


Raquel is the principal x-ray technician and infection control monitor at Centercare. She is originally from Wisconsin and came to us five years ago with a background in optical healthcare and in photography. She has received extensive training in radiography and in sterilization and is the principal trainer for the dental assistant externs that are sent to Centercare from schools around the valley. Her camera skills are much used as well with the large amount of intraoral photography that we do.
Out of the office, Raquel spends weeks every year as a mentor to socially challenged teens in urban Phoenix and in out-of-town camps. Raquel is a professional photographer and spends much off time shooting jobs and entering competitions.


Heidi Niebla

Heidi Niebla Centercare staff


Heidi did her formal dental assisting training at Arizona College of Allied Health and spent her extern training time with us here at Centercare. Her assisting skills and winsome personality has made her the darling of her patients and coworkers both.
In the years she has been with us, Heidi has developed a broad understanding of dental treatment and has the added advantage of being able to communicate that bilingually. She is technically adept and is one of the assistants chosen to run the software that builds our digital single-appointment crowns. Heidi is a skilled surgical assistant and is heavily involved in the whole process of surgical reconstruction at Centercare, communicating with suppliers, managing the digital workups prior to surgery and assisting the actual surgery.
Heidi is married and has 2 daughters, 5 and infant.
