Dr. Sims then spent two years in South Africa volunteering for his church. Upon returning, he relocated to California and attended dental school at Loma Linda University. Dr. Sims is now calling the valley home, to be near his family and give care to the community.
Outside the dental office, Dr. Sims enjoys spending time with his wife, son and daughter and her family. He shares dedication to the community by volunteering his time to provide free dental work for under privileged children. In his remaining time, Dr. Sims finds relaxation boating on the lakes around the valley. Dr. Sims is truly an asset to the community.
Dr. Liz Wallmann
I’m Dr. Liz Wallmann, and I am so excited to have joined Centre for Progressive Dentistry. I know that most people don’t love going to the dentist, and it is my goal to keep you as comfortable as possible while providing the highest quality of care. I do my best to treat every patient the same way I would treat my family.
I am originally from St. George, Utah. After graduating from high school, I attended Brigham Young University where I received a degree in statistics. I completed my dental education at the University of Texas Health Science Center at San Antonio Dental School. I received additional training as a part of an advanced education in general dentistry residency, which I completed at the Audie L. Murphy VA Hospital in San Antonio, Texas. Since completing my residency, I have been actively involved in study clubs and continuing education in order to stay up to date and continue to provide the level of care you deserve.
I have come to love Arizona in the years I have spent here and am honored to call it home. I love baseball and am an avid Diamondbacks fan; I can regularly be found at Chase Field during baseball season. I also love Disneyland and make trips out to Anaheim as often as I can. I enjoy spending time with my family and am lucky enough to have some family members here in the valley.
I am excited to have joined the exceptional team at Centre for Progressive Dentistry and look forward to getting to know all of you!
Dr. Danielle Bitton
Dr. Danielle “Dani” Bitton is excited to call The Centre for Progressive Dentistry home again after a 7-year hiatus to continue her academic studies and attend dental school. She first came to this practice as a dental assistant in 2007 after moving to Arizona from Idaho. While assisting her mentor, Dr. Thomas Sims, she discovered her passion for teeth, people’s smiles, and providing exceptional dental care to patients. Dr. Sims and the rest of the dental family at The Centre for Progressive Dentistry were a great support and motivator in helping her to make the decision to continue her education and become a dentist herself.
She completed her dental education at Midwestern University College of Dental Medicine- Arizona where she graduated with honors and was awarded the prestigious William S. Kramer Award of Excellence and the Russell O. Gilpatrick Award, given to the student who excelled throughout their four years of dental school. With the perspective as an assistant, and now a dentist, Dr. Bitton holds herself to the highest standard in providing exceptional care delivered with a gentle touch.
“What a great opportunity I have to combine two of my passions- people and teeth!
I am dedicated to your comfort and caring for your smile for years to come.”
Dr. Bitton is excited to return home to The Centre for Progressive Dentistry, where she can continue to put “People First, Teeth Second.”
Out of the office you can find Dr. Dani enjoying life with her husband Josh, and their three children, Berkley, Blake, and Beckam.
