Jennifer Sibo, DDS, FAGD, D. ABDSM

Jennifer Sibo has practiced locally in Castle Rock and Denver, but her love of dentistry started much earlier. While attending Liberty High School in Colorado Springs, she began with a job as a sterilization technician for a group of oral and maxillofacial surgeons - and quickly worked her way up to a surgical assistant both in office and in hospital operating rooms. She earned a degree in biology from the University of Colorado and her professional Doctor of Dental Surgery degree from the University of Minnesota.

In 2017, Dr. Sibo earned her Fellowship (FAGD) from the Academy of General Dentistry (AGD). This award is one of the most rigorous dental continuing education awards offered today. Upon completing her fellowship and earning this prestigious honor, she joined an elite group of less than 5 percent of all general dentists.

In 2021, Dr. Sibo earned her diplomat status with the American Board of Dental Sleep Medicine. Less than 25 dentist in the state of Colorado have this designation. Dr. Sibo assists patients in treating snoring and obstructive sleep apnea with oral appliance therapy.

Dr. Sibo is proud to be a member of the Smile Source network of extraordinary dental care) practitioners, who strive to provide patients with the best care available.

Mercy Vaska, DMD

Dr. Mercy Vaska is passionate about the benefits of a healthy smile. Not only is smiling a universally recognized expression of happiness that can unite us all, but smiling is proven to elevate mood, lower blood pressure, and increase life expectancy. 

Dr. Vaska began her pursuit of helping others achieve confident smiles by graduating Magna Cum Laude from the University of South Alabama with a B.S. in Biomedical Sciences, and she received her DMD from the University of Alabama at Birmingham. In order to provide the best care for her patients, Dr. Vaska believes in a lifetime process of growing and continuing education. 

Dr. Vaska moved from Alabama to Colorado in 2018 to pursue her dream of helping others through dentistry and to be near the mountains. Dr. Vaska practiced in Denver prior to moving to Highlands Ranch with her husband, Erik, and their cat, Mia. And she could not be happier to now be part of the Peak View Dental family! Outside of the office, Mercy loves spending time outdoors–hiking (especially 14ers!), skiing, backpacking, and rock climbing. She also enjoys live music, cooking, painting, and traveling.
