Dr. Simms
Thomas M. Sims, DDS

A family oriented individual, skilled dentist, active youth leader, and community volunteer, Dr. Thomas Sims makes the dental experience a personal one. His 25+ years of dental experience and continued education in the dental field ensure you will receive painless, top quality care. He strives to keep up with the latest technology and bring up-to-date equipment into his beautiful dental practice. Dr. Sims is a proud member of the American Academy of Cranial and Facial Pain, American Academy of Cosmetic Dentistry, and has successfully completed education in Motor Nerve Reflex testing, Dental Sleep Medicine and Temporal Mandibular Disorders. In his practice, he provides dental treatment including crowns and bridges, composite fillings, implant dentistry, full mouth rehab, treatment of craniofacial pain, temporomandibular disorders, sleep disordered breathing, and obstructive sleep apnea.

Dr. Sims might be a familiar face to some as he is a third-generation Arizonan. He graduated from Saguaro High School and continued his education at Arizona State University. 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 Thomas Sims. 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 Thomas Sims and look forward to getting to know all of you!
