Aesthetic Nurse
Over the past 13 years, I have dedicated my career to the field of medical aesthetics & wellness, nurturing my passion for helping clients achieve their wellness and aesthetic goals. My journey began during my college years, where I simultaneously pursued a degree in organizational communication studies while working at a renowned med spa. This experience served as a catalyst for my growing fascination with the world of aesthetics and wellness.
Following my graduation, I pursued my interest in aesthetics and wellness by obtaining an aesthetician license. This allowed me to delve deeper into the practical aspects of the field, gaining hands-on experience serving as Practice Manager and clinical roles at various plastic surgery clinics and med spas. As my expertise and profound understanding of the medical aesthetic industry expanded, I found myself collaborating with several startups, aiding them in establishing their own successful spa ventures.
Motivated by a relentless pursuit of excellence, I decided to take the next significant step in my career and enrolled in a program for an accelerated second bachelor’s degree in nursing. This educational endeavor has equipped me with a comprehensive understanding of the medical intricacies involved in providing holistic care to patients, further enhancing my ability to blend my aesthetic/ wellness expertise with a profound understanding of medical principles.
My diverse background ranging from extensive practice management, consulting, to hands-on experience in various medical aesthetic settings, has enabled me to cultivate a unique skill set.
