Owner, Master Aesthetician

Christina was inspired to become an aesthetician when she found herself struggling with acne as an adult and went to a dermatologist at a med spa. She received skin care treatments by a medical aesthetician and was hooked after that. Christina's service provider played such an important role in the healing of her acne, not only physically but mentally and emotionally as well.

Christina's background was health care and special education. She decided to take the leap of faith and go to school to become an aesthetician, and within two years of being an aesthetician Isella Day Spa was born! Throughout the many years Isella has been operating, her heart kept bringing her back to the reason she got into this business in the first place. She decided to obtain her master aesthetic license, brought on a medical director and started changing the course of her business. Sixteen years later–– that dream has evolved into Isella Aesthetics!
