She began her career as a registered nurse before receiving a Master of Healthcare Administration (MHA) and a Doctor of Nursing Practice (DNP) degree, both from the University of Washington. Dr. Julie has specialty training in a wide variety of aesthetic medicine practices including the application of Botulinum Toxin A (BOTOX), Dermal Fillers, aesthetic laser, PRP/PRF, and more. “Aesthetic Medicine and Skin Health are my passion! I love my patients – and even more, seeing the look of joy on their faces when they see their results. I can’t imagine doing anything else.” Outside of the clinic, Dr. Julie loves spending time with her family, volunteering at school for her daughter Olivia, and the local foodie scene.

Olga Yudich – DNP, ARNP

Aesthetic Nurse Practitioner

Olga is a graduate of the University of Washington’s prestigious School of Nursing where she graduated with her Doctorate in Nursing Practice. She first learned about the aesthetic industry as a DNP student, where she met Dr. Julie in her final clinical rotation. “I was immediately intrigued. There was this whole other side of medicine where I could use my creative talents, make a difference, and apply the years of education and bedside experience I acquired.” Upon graduating, Olga started her career working as a cardiology nurse practitioner, all the while completing numerous aesthetic training, shadowing, and training with Dr. Julie at Radiance. In her spare time, she loves to stay active, spend time with her loved ones, and escape the Washington rain when she can with her husband and fur baby Ava.
