Patient education is one of her passions as is getting to know patients and their families as they deal with their allergies (and asthma and eczema), improving their health along the way.

Kalene

LPN, Clinical Manager

Kalene has been working in healthcare since 2016, beginning her career in allergy and immunology. After some time, she transitioned into orthopedic surgery to explore a different path but soon realized her true passion lies in allergy and immunology. She returned to the field where she felt most fulfilled and has since had the opportunity to work alongside a variety of providers. Over the years, Kalene has grown into leadership roles, initially as a supervisor and now as a clinical manager. In her current position, she manages both the clinical team and administrative staff, all while continuing her education in healthcare and leadership to further advance her career and expand her skills.
Outside of work, Kalene is an avid fan of murder and crime podcasts. They’re her go-to for keeping her brain engaged while she’s doing just about anything. She enjoys diving into mysteries, unraveling twists and turns as the stories unfold. When she’s not listening to podcasts, Kalene can be found experimenting in the kitchen, baking up a storm, or binge-watching TV shows—she’s always starting a new series. And yes, she might get caught stress-cleaning the house, either to avoid something else or simply because a shiny surface caught her attention. Sticking to just one hobby is practically impossible for her; Kalene is always jumping between interests, trying new things, and constantly learning—whether it’s a new hobby or a random fact that piques her curiosity. She loves variety and keeping life interesting, with no clear favorites in sight.

Vincent

Medical Assistant

I am a first year medical assistant with SanTan Allergy being my first place of employment fresh out of school. I am 20 years old and love to play and watch sports, be outdoors, and hangout with friends and family. I have lived in Arizona my whole life and actually struggle with asthma myself. I feel like having asthma myself allows me to be able to connect with the patients I’m interacting with as I know how hard life can be. I have really come to enjoy all of the things medical assistants do such as caring for patients and helping them do the things they love to do so everybody can be happy. In the future, I am going back to school to become a CST (Certified Surgical Technician). I am always looking to learn new things and expand my knowledge to not only the allergy and asthma side of the field but everything in between. I am willing to help when and where I am needed no matter what lies ahead.
