FOUNDER, MSN, FNP-C
Welcome to Onyx Med Spa! We are so glad you are here. A little about me:
I started my career as a family nurse practitioner, spending a decade in urology and oncology. After losing my husband in 2014, I felt a deep need to create something meaningful for both myself and my daughter. My own journey has been shaped by resilience facing personal challenges and learning the importance of perseverance. Working in a challenging environment during events like the Marshall fire pushed me to reassess my priorities. I wanted more flexibility for my family, and a supportive work environment where everyone felt valued. That’s what inspired me to open my med spa. This is also why I named it Onyx Med spa, as Onyx symbolizes strength, resilience, and transformation. I am so grateful for the journey and the opportunity to help others feel confident and cared for everyday.

Hi, I’m Megan! As a Colorado native, I have always had a deep appreciation for natural beauty - both in the world around me and in the individuals I work with everyday. I began my nursing career as a Bone Marrow Transplant nurse, where I solidified clinical skills and developed a strong understanding of patient care and safety. Along the way, I discovered my passion for aesthetic medicine. Now as a nurse injector, I am dedicated to creating a safe, honest, and welcoming environment to deliver personalized and effective treatments tailored to each individual’s goals.
When I am not at the med spa, you can find me enjoying the Colorado lifestyle: hiking, playing pickleball, or skiing. I also love curling up with a good book, binge-watching a great show, and spending quality time with my loved ones.
I look forward to meeting you and continuing to help clients feel supported, confident, and empowered!

Hi! I’m Amanda! I grew up in Colorado and have always loved spending time in the mountains - hiking, camping, and making memories with friends. After receiving my Bachelors in Psychology and Public Health from CU Boulder, I went on to complete my Bachelors of Science in Nursing at Anschutz Medical Campus. I started my nursing career in 2023 as a Bone Marrow Transplant nurse, where I found a passion for building meaningful connections, supporting patients through challenging times, and continually expanding my education in healthcare and oncology.
Over time, I realized I wanted to blend my love for caring for others with my creative side, which led me to aesthetic medicine. I’m so excited to bring everything I’ve learned in nursing to Onyx Med Spa and to help others feel confident, supported, and naturally beautiful.
I can’t wait to get to know you and help you feel your best - inside and out!

Hi, I’m Kaylee! I have been a nurse for over 6 years, with most of my background in emergency medicine, but aesthetics has always been my passion. I grew up in Wisconsin and moved to Colorado as a travel nurse, where I discovered my love for combining medical knowledge with the art of aesthetics. What excites me most is being able to help people feel confident, empowered, and comfortable in their own skin—it’s such a rewarding part of what I do.
When I’m not in the office, you can usually find me with my family, friends, or my Pomeranian. I love staying active with the gym, Pilates, and (my favorite) line dancing the night away.

"they are both amazing and caring and great at what they do"
OMG! This place…. Richelle and Amanda have been fantastic. I came here wanting to find a path to better looking skin and help with post menopausal wellness/weight loss. Richelle and I are working on refreshing my 56 year old Colorado weathered face. She is great at letting me know what they offer and listening to my thoughts and what I can afford. Amanda is helping with my wellness/weight loss. She is knowledgeable about the medications available and supplements you can use to support your journey. They are both amazing and caring and great at what they do.

"she is attentive, thorough, and has an eye for detail which is so important when it comes to injectables"
I have been seeing Richelle here for Daxxify for a while now and will never go anywhere else! Besides the product itself being amazing, Richelle is truly the best at what she does. She is attentive, thorough, and has an eye for detail which is so important when it comes to injectables. I have been to a lot of med spas around Denver and Onyx stands head and shoulders above the rest.
AMY
"she listened to all my concerns, gave me other options I could do"
Amanda is the best! I got a my first chemical peel and was super nervous. She listened to all my concerns, gave me other options I could do, and made me feel I was making the right choice for me. Throughout the process from applying the chemical peel and to when I was done peeling, she answered all my questions, checked in to see how I was doing, and even checked in after the week was up to see how everything went!
