Lillian Varedi, CST

Lillian is originally from Hilton Head, South Carolina, and moved to Denver and joined our team in 2024.

She has been in the medical field for over 25 years, as a surgical technologist in general and dermatological surgery. Lillian has enjoyed the transition to a clinical setting because she gets to help patients throughout their healthcare journey, not just in surgery. Lillian coordinates our patients in clinic and also communicates with your referring and primary care physician to ensure your entire medical team is well-informed.

Spine related pain can leave patients feeling overwhelmed and confused.
