Meet the Founder

Welcome to KÁLLOS, where beauty meets expertise, and every client is celebrated as a masterpiece. I'm Kassi Jillson, a Board-Certified Nurse Practitioner with a passion for aesthetic mastery and a dedication to enhancing natural beauty.

With over 20 years of experience within the healthcare industry, and seven years of experience in the aesthetic industry, my journey began in intensive care before transitioning to specialize in injections and the artistry of aesthetics. Hailing from Minnesota, I've had the privilege of training alongside some of the nation's leading providers, honing my craft to deliver unparalleled results.

At KÁLLOS, my mission is simple: to empower and elevate. I believe in the transformative power of subtle enhancements and the importance of personalized care. With a commitment to excellence and ongoing education, I strive to exceed expectations while fostering meaningful connections with each of my clients.

From advanced injectables to innovative skincare solutions, every treatment is tailored to enhance your natural beauty while preserving your unique essence. When not injecting, I am a proud wife and mother to 3 kids (Lydia, Sam, and Nora)who inspire me with their boundless energy, creativity, and curiosity. Their presence is woven into my practice, reminding me of the importance of nurturing both body and soul, and I am dedicated to creating a practice that reflects these values.

She answers all questions, listens and responds with solid & actionable advice and is never pushy. No treatment/ consult is too small for her. I found her approach each appointment I’ve had with the same professional approach & care."

Kassi truly gets to know what the goals of the customer are, thoroughly explains each procedure, and then provides a price before starting. I highly recommend"
