I've been a part of the beauty industry for almost a decade, and I love the fact that I've never stopped learning or growing as things evolve.

I love spending time with my husband, son, and our two corgis! It is never a dull moment in our house, especially with a 4-month-old baby!

My specialty is liquid facelift with HA dermal fillers. I also love bio stimulators such as Sculptra and PRFM, and I will always love injecting all the neuromodulators.

I love working with Scarlett, Neogen, and Agnes at Catalyst. I am so glad to be at Catalyst and a part of Dr. Mathison's vision.

After graduating college, I began my professional career as a float nurse at Essentia Health. The path I was on ultimately led me to my career at Catalyst, where I'm able to dive into my passion for dermatology and women's health.

In my free time, I love to travel, do anything outdoors, and learn!

I’m Alexis - I have 3 years of NICU experience and have recently pursued my passion of becoming a Nurse Injector. My goal is to enhance people’s natural beauty by making them feel confident in their own skin.

I specialize in SkinPen microneedling + PRP as well as the EmSculpt NEO body contouring device with more to come!

In my free time you can catch me running around with my 2 kiddos, at the lake, or spending quality time with family and friends.

My passion for art and photography led me to fall in love with aesthetic nursing. Aesthetics allows me to use my artistic eye to make women and men feel more confident and become the most beautiful versions of themselves. Along with Botox, lip and cheek fillers are my favorite area to use injectables to combat the aging process and increase the confidence of my patients.

My husband and I, along with our 3 beautiful children have lived and farmed in the Jamestown area for the past 25 years.

Chrystal Rittenbach graduated from the University of Jamestown with a BSN in 2001. She is licensed in North Dakota and Minnesota.

I was born and raised in Fargo. I worked as a Real Estate Agent for two years, in Family Practice for two years, in an OB/GYN clinic for 9 years, and in Maternal-Fetal Medicine for 2 years.

My calling as a nurse has always been taking care of people and making them feel beautiful inside and out. I have a passion for anti-aging, beauty, make-up, aesthetics, and plastic surgery.
