I started my practice in 2005 with the help of my wife initiating the philosophy of treating everyone like family and friends. I pride myself on a solid staff foundation built one team member at a time. We take the time to get to know our patients and over time their extended families as most of our practice have been built from inpatient referrals.

Zerada has been with our dental family since October 2008. She went to  Coastal Carolina where she graduated as president of her class and with honors in 1990.  In her 26 years of practicing dental hygiene, she has become licensed in 3 states, certified in anesthesia and nitrous.  Much of her philosophy comes from staying abreast of evidence-based research and knowing that oral health is encompassed with the whole body.  She believes in treating every patient with respect and educating them so they are invested in their oral health.

Zerada is named after her great-grandmother, she is married, has 3 grown children (4 counting her husband, who thinks he's Tom Selleck) and loves the company of her family & friends.  In her spare time she enjoys vacationing, cooking, working out, gardening, and making a "honey do" list for Tom.  The "golden rule" and laughing at herself keeps life simple.


Front Office

Becky has been in dentistry for over 35 years. She joined our dental family in February 2013.  Her first job after graduating from dental assisting school was an assistant in a children's dental office. Having worked as an assistant and the front office she has great knowledge and understanding of both aspects of dentistry.

Becky is married, has two sons, a daughter-in-law and loves being a grandparent.  She enjoys reading, knitting and of course watching the Colorado Rockies and Denver Broncos.



Amanda has been with our dental office since June 2014. During her last year in high school, she also attended dental assisting school, so she graduated from high school and assisting school at the same time. She is the youngest in the dental family she keeps us up on all the new trends. 

However, at home Amanda is the oldest sibling, she has two sister's and a brother, that she helps in guiding them in the right direction.

Amanda enjoys being with her loving family, traveling, snowboarding and just being in the outdoors. Of course, she hangs out with her friends! Oh, and she likes cookies.


Front Office

Elsa joined our dental family in February 2015. She has many years of experience in different dental specialties, such as pedodontics and orthodontics, but is now enjoying her continued learning of general dentistry. While not working in the dental field she worked for a local candy company in accounting and was given the chance to learn all about making chocolates and traditional hard candy. Something everyone in the dentistry should know!!

Elsa is married, has two grown children and two lovely granddaughters that live close by, allowing for lots of great fun and laughter. When she is not working, Elsa enjoys spending time with family, friends, gardening and being outdoors exploring new adventures.

She has been a wonderful addition to our dental family!


Dental Assistant

Emmalisa has 3 boys that are highly active in several sports including football and wrestling, which keeps her VERY busy. As a family, they enjoy outdoor activities like hiking, biking, and camping, to name a few. There is now a new member of her family, a Harley Davidson Sporty.  Emmalisa comes from a large family, consisting of six nieces, one nephew, many Aunts, Uncles, Grandparents and her parents, .. need we say more? She enjoys making party decorations for her families many celebrations. Don't ask about spare time... she hasn't any.

We have truly enjoyed her sense of humor, professionalism and it was seamless when she joined our dental family.



Zulma joined our dental family in July 2017. She was an assistant for 13 years and then went back to school to become a dental hygienist. She graduated from Colorado Northwestern Community College with honors in 2014. She maintains a high level of integrity by applying the latest evidence research base treatments while being gentle at the same time. Her philosophy is to treat patients how she wants to be treated.

Zulma lived in beautiful Summit County for 20 years and recently moved to the Denver area with her husband, son, daughter and miniature poodle, Rosie. Together they enjoy exploring new areas and learning new things. The number one thing they love the most is having daily meals as a family. In her free time, she loves spending quality time with her friends.
