Dr. Wallin, a cosmetic dentist serving Casa Grande, Arizona, practices dentistry with one primary goal: to provide excellence in dental care. Dr. Wallin received his dental education at the University of the Pacific, located in San Francisco, and known for it’s progressive approach to patient care. The “Humanistic Approach” is a way of teaching that each patient is much more than just the teeth we treat and that relationships with our patients are key to understanding the needs of individuals. Dr. Wallin’s practice is modeled after the “humanistic approach” he was taught in school. Dr. Wallin is known for his clinical competence and ethical integrity and loves being able to play a small part in redefining a new level of patient care among some of the best dentists and dental specialists in the Casa Grande and Phoenix area. Dr. Wallin loves the charm of Casa Grande and most importantly the warmth of the people who comprise this community, and is committed to the growth and health of our friends, family, neighbors who compose our patients.
