Dr. Brad Pfeifle, DDS

Dr. Brad Pfeifle, DDS

You are probably wondering how to pronounce Pfeifle (It`s fi-fle). To make it easy, I go by Dr. Brad. Or others call me “Brad The Dentist”.

My family moved to Arizona in 2003 from a town of only 1,000 people in North Dakota. I graduated high school in Mesa, and then attended Arizona State University (go Devils!). I must have forgotten how cold the midwest is, because I returned to the land of snow and mosquitoes to attend dental school at the University of Minnesota.

After school, I commissioned in the Air Force, and finished top of my class from a rigorous post-graduate “Advanced Education in General Dentistry” residency. I served over 5 years as a dentist in the Air Force, and had the privilege of living in Florida, South Korea, and Germany.

I developed a love of traveling and exploration, and a passion for discovering new cultures. Besides traveling, I love ice cream, especially cookies and cream. Luckily, I also enjoy spending time in the gym, and hiking.

I am a huge dental nerd, so I am constantly learning the newest dental techniques and technologies to bring to our practice.

I am beyond excited to join such a great team and community.

I look forward to getting to know you!

Dr. Sadia Zubairi, DMD

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

Due to my husband’s training in pediatric cardiology and electrophysiology, I then had the opportunity to practice dentistry in Maryland, Arkansas,Tennessee, and Virginia! I moved here to beautiful Arizona along with my family when my husband joined Cardon Children’s Medical Center.

I take pride in providing my patients with the highest quality dentistry in the most compassionate and gentle way possible. When I’m not at work, you will find me hiking, traveling, and spending quality time with family and friends. I am absolutely excited to be part of the Sonoran Desert Dentistry and look forward to meeting you!

Dr. Theresa Herro, DMD

Meet Dr. Herro

Dr. Herro was born and raised in Arizona. Upon 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. Due to the dynamics of the field, growth through learning new technology continues to be paramount to her dedication in providing excellence in care and treatment. It is through integrity and compassion that she cares for her patients and always acts in their best interest.

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 through 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 because health and fitness are an integral part of her life and a source of discipline she lives by. However, as she loves a good balance, you may also find her winding down at one of Arizona’s spectacular Northern wineries (but maybe she’s a bit partial being an AZ native).

Whether your goal is to eliminate pain, straighten your teeth or simply have a better, brighter smile, Dr. Herro would love the chance to help you achieve your goals and increase your quality of life.

Dr. Jossen Gastelum

Hi! I’m Dr. Gastelum, and I am excited to welcome you to Sonoran Desert Dentistry! I consider myself a true Arizonan at heart—I was born and raised in Tucson, Arizona where I completed my 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 my time at Louisville, I was actively involved in leadership roles with various dental organizations and even proudly served as the President of the local Hispanic Student Dental Association chapter.

After graduating and then practicing in Louisville, I returned with my puppy Louie to my hometown in Tucson where I served the community I was born & raised in for over two years. These days I am so excited to be based here in beautiful Scottsdale, Arizona and to have the opportunity to serve this wonderful community. When I’m not at the office you may find me taking advantage of the sunny outdoors with my pup, traveling the world (for business and for fun), or enjoying the many restaurant options in the area (I’m a huge foodie).

Like all of the providers at our office: I am committed to providing personalized care, and I make it a priority to invest my time into the most advanced continuing education available to ensure that you have a dental experience that is nothing short of exceptional. My current interests include conservative adhesive dentistry and cosmetic dentistry expanding the options for comprehensive dental and facial aesthetic results. I’m eager to meet you and to provide exceptional dental care alongside my amazing Sonoran Desert Dentistry colleagues.

Meet The Team



A great hygienist, with a real ability to connect and understand people, is how Dr. Brad describes Dental Hygienist Anna. “My patient’s rave about Anna and how comfortable and confident they feel when they are in her chair” said Dr. Brad. A graduate of Lane Community College in Eugene, Oregon, Anna was attracted to dentistry for the opportunity to truly help people and create beautiful, healthy smiles. She was attracted to Sonoran Desert Dentistry for the opportunity to accomplish both of those and work with a team that is committed to advancing their skills and knowledge with dentistry and technology. “I joined this great team in 2011 and feel blessed to call this wonderful group I work with my friends. When I’m not at work, which, by the way, I love, I enjoy baking, traveling and hiking. My grandmother, aunties and uncles live in Anacortes, Washington, my best friend lives in Oahu, Hawaii, and my family is in Eugene, so these are the places I enjoy traveling to the most. Last but not least, I adore spending time with my cat Lucy!”



Hi, I'm Stephanie and I am a dental hygienist! Every day is an opportunity to make a difference in the oral health of my patients. I have always been passionate about living a healthy lifestyle, and that led me down the road to dental hygiene. I look forward to helping patients understand the value of the oral-systemic/health connection.

In my free time, I enjoy traveling, hiking, and strength training at the gym. Some of my favorite places I have traveled to are Greece and Iceland.



My passion for helping others is what led me to become a dental hygienist. I prioritize my patients' needs to help them have a comfortable positive experience at the highest quality of care. When I am not at work I am typically enjoying the outdoors. I love hiking, running, skiing, snowboarding, volleyball and traveling. I have taken some big road trips from New Hampshire, my home state, to Florida and from New Hampshire to California! Through my travels, I can say that the sunny state of Arizona is my favorite!
