Colleen Basham, MSN, APRN, FNP-C
Bachelor & Master of Science in Nursing from Regis University • Board-Certified Family Nurse Practitioner by American Academy of Nurse Practitioners • Member of American Association of Nurse Practitioners
Colleen Basham is a certified nurse practitioner, specializing in dermatology. After five years working in an all-natural spa, she was inspired to pursue a nursing degree at Regis University where she graduated with honors. She then went on to work in cardiology, internal medicine and public health before returning to Regis University for her nurse practitioner degree. With a range of medical experience under her belt, Colleen has found her way back to her original love – skincare. Having struggled with her own skin issues over the years, she is forever passionate about helping others feel truly confident in their skin.
As an Austin native (that’s right, y’all), she considers Colorado home after almost two decades in Northern Colorado. When not exploring all things skincare, Colleen loves to take advantage of everything Colorado has to offer, adventuring with friends and her loyal pup, Althea. She is honored to be part of the Seitz Dermatology team, excited to connect with the Wellington community and eager to start helping patients reach their skin health goals.
