Tori Flodin

Practice Manager

Originally from Chicago, Tori moved to the desert 20 years ago. She is a Certified Aesthetic Consultant with over 18 years experience in salon and spa management. Her focus shifted to medical aesthetics 12 years ago when she became the Spa Manager for the largest laser training school in the country and helped open their second location in Dallas, Texas a few years later. She then became the Director of Destination Courses, where she coordinated laser and injectable trainings all across the country. While she loved the experience of helping people embark on new careers, she missed working in an office where she could see each patient’s transformation from start to finish.

She joined our team in November of 2017 and immediately found her home! Her attention to detail and love of organization makes her the perfect person to ensure the office runs smoothly. She is passionate about guiding patients on their health, wellness, and aesthetic journeys – and always does her best to create an unforgettable patient experience. Her knowledge and personal experience of treatments and procedures makes everyone feel comfortable when scheduling.
