Since we've opened our doors, in 1995, we've been trusted by our patients to provide quality dental care for their families. We now enjoy 3 generations of happy, healthy patients who have helped build this practice into the "Family Dentistry" we are today
Dr. Keen was born and raised in Southern California, living in the Rancho Cucamonga area since 1990. He graduated with a biology degree in 1985 from USC, and graduated USC Dental School in 1989, following his passion for cosmetic dentistry. Dr. Keen’s ultimate mission is to deliver the highest quality dentistry for his patients in a gentle, caring environment.

When he’s not in the office, Dr. Keen takes pride in being a family man. He loves spending time with his wife, Diana, and their two sons Bryce and Blake.
