The Doctors

Your dentists

A four-doctor team means you're never far from an appointment, a second opinion, or evening availability with Dr. Brad.

Dr. Brad Pfeifle, DDS

"Brad The Dentist" — pronounced fi-fle

Dr. Brad moved to Arizona from a town of only 1,000 people in North Dakota back in 2003, graduated high school in Mesa, then attended Arizona State University (go Devils!) before heading back to the cold to attend dental school at the University of Minnesota.

After school, he commissioned in the Air Force and finished top of his class from a rigorous post-graduate Advanced Education in General Dentistry residency. He served over five years as an Air Force dentist with the privilege of living in Florida, South Korea, and Germany.

A self-described "huge dental nerd," Dr. Brad is constantly learning the newest dental techniques and technologies to bring to the practice. Outside of the office: ice cream (cookies and cream), the gym, hiking, and discovering new cultures around the world.

Dr. Theresa Herro, DMD

President, Central Arizona Dental Society

Dr. Herro was born and raised in Arizona. After graduating from Arizona State University with dual bachelor degrees in Human and Family Relations and Chemistry, she attended Midwestern University, College of Dental Medicine where she graduated with honors in 2012. Since then, the Valley of the Sun has been her exclusive home for practicing dentistry.

Dr. Herro proudly sits on the board for the Central Arizona Dental Society (CADS), a constituent of the Arizona Dental Association (AzDA), as President. She also donates her time, knowledge and expertise educating medical students at the University of Arizona's College of Medicine on oral disease prevention, health and wellness.

When she is not in the office, you can find her on some of the local hiking trails — or, given a good balance, winding down at one of Arizona's spectacular Northern wineries (a bit partial, being an AZ native).

Dr. Sadia Zubairi, DMD

"The highest quality dentistry, the most compassionate way possible."

Dr. Zubairi graduated with a double major in Biology and Psychology from the University of California, Davis, then pursued her childhood passion of becoming a dentist — graduating with honors from Kornberg School of Dentistry at Temple University in Philadelphia.

Due to her husband's training in pediatric cardiology and electrophysiology, she practiced dentistry in Maryland, Arkansas, Tennessee, and Virginia before moving to Arizona when he joined Cardon Children's Medical Center.

She takes pride in providing patients the highest quality dentistry in the most compassionate and gentle way possible. When she's not at work, you'll find her hiking, traveling, and spending quality time with family and friends.

Dr. Jossen Gastelum

A true Arizonan at heart — born and raised in Tucson.

Dr. Gastelum was born and raised in Tucson, Arizona, where he completed his Bachelor of Science in Physiology at the University of Arizona before pursuing dental training at the University of Louisville's School of Dentistry in Kentucky. During his time at Louisville, he served as President of the local Hispanic Student Dental Association chapter.

After graduating and practicing in Louisville, he returned with his puppy Louie to Tucson, where he served his hometown community for over two years before joining Sonoran Desert Dentistry in Scottsdale.

His current interests include conservative adhesive dentistry and cosmetic dentistry, expanding the options for comprehensive dental and facial aesthetic results. Off the clock he's outdoors with his pup, traveling, or working through the area's restaurant scene — he's a huge foodie.
