Joseph O’Leary, DDS, grew up in Rockford, Illinois. He attended college at the University of Notre Dame, graduating in 1985 with a Bachelor of Science. After completing his dental degree at the University of Illinois in 1989, he came to Colorado and furthered his education at a dental residency program at St. Joseph Hospital in Denver.

His residency allowed him to advance his surgical skills and learn to manage medically compromised patients. One-third of his time in residency was also spent at Children’s Hospital of Denver, giving him additional experience in meeting the needs of younger patients.


Dr. O’ Leary became the first dentist in Lone Tree, Colorado, when he founded Meadows Dental Group (formerly known as Arbor Dental Group-Lone Tree). He has been in practice in Colorado for over 30 years and in the Lone Tree location for over 20 years.
