Dr. Ron Lambert
Dr. Lambert was drawn to dentistry. He was five years old when he first decided to become a dentist. In part, he was following in his father's footsteps. But, alongside of this, he always had a desire to help people and enjoyed hobbies that required a great deal of dexterity. Dentistry allowed for him to benefit from both of these at the same time. To pursue his adoration for dentistry Dr. Lambert attended and graduated, with honors, from the University of Colorado School of Dentistry in 1991. After completing a General Practice Residency at the University of Washington he returned to Colorado to practice in Louisville for many years. Dr. Lambert's passions for Dentistry influenced his philosophy of practice and lead him to become a Clinical Instructor at the University of Colorado School Dentistry. While there he focused on the complex subject of bite and the adverse effects of the often undiagnosed and untreated improper forces that lead to early failure of many restorations and fracture or loss of natural teeth. His intimate knowledge of Dental Anatomy has also made him highly skilled in the art of Cosmetic Dentistry. Dr. Lambert practices with a high degree of empathy for his guests. Understanding that most dental treatment is tolerable at best, he makes every effort to address the uncomfortable nature of treatment and the anxiety it may evoke. It is our tremendous pleasure to have Dr. Lambert here in our practice. We know that you will come to appreciate and enjoy him as much as we do!
