Meet The Hygienists
I have been a practicing dental hygienist in Tucson, Arizona since 1995. After attending Arizona State University, I received my Associates of Applied Sciences degree in Dental Hygiene from Pima Community College. The field of dental hygiene is rapidly evolving. To keep current and continue advancing my clinical skills, I attend numerous continuing education courses in all fields of dentistry as well as read professional publications. I am also a member of the Arizona Dental Association. Most recently, I have become State Certified in Soft Tissue Laser Therapy. Since 1996, I had worked in the same dental practice. For the past 20 years I have worked in the same dental practice. As of January 2017, I transitioned to Dr. Bell’s practice. Here, I have been afforded the opportunity to treat our patients with the tools and technology of dental hygiene above the standard of care. I am pleased to continue working with all my long-term patients and look forward to establishing new ones. I enjoy treating and maintaining my patient’s periodontal health and smiles at this practice. I am married and have two amazing children. My wife is a practicing dental hygienist as well. Outside of work, I enjoy family, exercise, sports (especially U o A), and numerous outdoor activities.

We have retired!
Retired as of April 2, 2021
After many years of working in the dental field, I made the decision to retire on April 2, 2021. The decision was difficult to make because I have truly enjoyed working with every single one of the dental practice’s (Dr. Bell’s) patients. I hope I made you feel welcomed and part of our dental office family. I poured my heart and hard work into making sure things were resolved however, in November 2020 our family was blessed with a beautiful grandson. The more I held him, my heart was stolen. I decided to take care of him full time. I can assure you that the office will continue to take care of you as well.

I am immensely humbled and touched by your confidence and loyalty throughout all these years; it means more to me than you will ever know.

I will be leaving you in extremely capable hands of my fellow hygienists whom I have tremendous confidence in.
