Meet The Team


Margie Williams, DDS

Dr. Williams has over 30 years of dental experience. She was introduced to dentistry as an assistant in her brother-in-law’s dental office and soon discovered her love for everything teeth. This led her to the Loma Linda University School of Dentistry where she graduated with a Bachelor of Science in Dental Hygiene.

After practicing hygiene for several years in a variety of settings, she obtained her dental degree at the University of Colorado School of Dental Medicine. She briefly held an appointment as a Clinical Instructor in the Department of Surgical Dentistry and still enjoys sharing her love of dentistry with future dental professionals. Some of her team members have gone on to become certified dental assistants, hygienists, and dentists!

Dr. Williams has a passion for learning and strives to educate her patients on all of the treatment options available to them. She believes patients should be able to fully participate in their care and choose the best treatment for themselves. Dr. Williams has a strong interest in providing comprehensive treatment including complex full mouth rehabilitation. Williams Family Dentistry is a true “family practice” with Dr. Williams being very comfortable caring for all members of the family.

Dr. Williams has been a resident of Central Park for many years where she lives with her family. Outside of the office, you’re likely to see her at one of the neighborhood pools or restaurants.


Molly Johnson, DDS

Dr. Molly Johnson has been a resident of Central Park since 2011 and loves the sense of community that makes our neighborhood so special. She enjoys treating so many neighbors and friends!

She is a graduate of the University of Colorado School of Dental Medicine, where she was elected to Omicron Kappa Upsilon (a national dental honor society).

Dentistry is a second career for Dr. Johnson. She attended Trinity University in San Antonio, TX where she played soccer and graduated with both bachelor’s and master’s degrees in Accounting. She spent 6 years working as an accountant, but ultimately found her work to be unfulfilling. Dentistry was appealing to her because it involves a lot of patient interaction, demands continuous learning, and always has advancements in technology. Her goal as a dentist is to make her patients feel comfortable and informed while providing high quality dental care.  She feels honored when patients recommend Williams Family Dentistry to their family members, friends and coworkers.  

Dr. Johnson lives in Central Park with her husband and daughter. She loves the Colorado outdoors and enjoys skiing, biking and cooking.

Dr. Johnson is a member of the American Dental Association, the Colorado Dental Association, and the Metro Denver Dental Society.

Nika Pesaran, DDS

Dr. Nika Pesaran was born and raised right here in Colorado, and early in her life she was sure of two things. First, she never wanted to leave this beautiful state, and second, she wanted a profession where she could provide preventative, comprehensive care to her community. She went on to receive a Bachelor of Science in Integrative Physiology at the University of Colorado at Boulder and her DDS at the University of Colorado School of Dental Medicine. After dental school, she moved to the Pacific Northwest where she completed her residency in Advanced Education in General Dentistry in Seattle, before she moved back to Colorado forever. Dr. Pesaran is passionate about providing the best care in a friendly, and comfortable environment. She hopes that everyone who sits in her chair has a positive experience and leaves feeling educated and empowered. 

When she is not practicing Dentistry, Dr. Pesaran can be found spending time with her family, teaching or taking yoga, cooking, traveling, and exploring all the incredible things this city and state have to offer.
