An Approach Rooted In Experience

Cambria Welling RN

With over 10 years of experience in the aesthetic field, Diana offers a unique combination of experience, knowledge, and artistry. 

Diana has been a practicing nurse since 2013, and in her continuous drive towards education, she went back to school and received her Master’s in Nursing-Family Nurse Practitioner degree in 2022.


She is often referred to as a “perfectionist” and focuses on delivering safe, beautiful, and natural results for each of her patients.

At the heart of Diana’s approach is her goal to create and deliver the most natural and beautiful results possible for her patients. She believes everything is equally important in your self-care journey: looking after your skin, replacing volume depletion, softening lines, providing education, implementing preventative aging measures, and becoming your own beauty bestie and cheerleader in life.
