"I love Onyx! Bobbi gives the best facial I’ve ever had! You don’t know how good a facial can be, until you’ve had one from Bobbi! In fact I won’t go to anyone else or anywhere else to get a facial. I trust Kristina fully with all my injection needs! She takes the time to sit down with you, listens to your wants, and explains your treatment very well. i love the atmosphere, it's clean and relaxing. Every employee I have encountered has always been very nice and helpful!"

Jessica G.

"I travel from Utah to come to Onyx & it is well worth the drive! I’ve loved all my procedures I’ve had here, but my favorite will always be my Dysport injections with Robin. The entire staff is so kind & professional too. Thank you Onyx for always going above & beyond for me as a client!"

Rachael H.

"Robin is amazing. I have been seeing her for years for injections and have never been disappointed. She has an artistic eye and is a perfectionist. She never rushes. She listens to what you want to see improved and masterfully makes the corrections. She is worth every penny. There is no need to shop around for a skilled injector. You will not find anyone better than Robin."


"Love Onyx and their staff are all so friendly! I did Dysport with robin and she is very knowledgeable and doesn’t over fill. I love how natural she keeps things but still gets the job done! McKenna is also amazing with product and has the best recommendations! Hands down recommend them!"

Aubrey S.

"Onyx is truly the best! Its location is easy to find and aesthetically pleasing when you first walk in. The girls at the front desk are so friendly and eager to help. Robyn and Kristina are highly skilled injectors and take the time to understand what end results you are looking for. I don't trust anyone else!"

Hannah D.

"I am currently 36 weeks pregnant and got the prenatal massage. It was my first time getting a massage and it was absolutely amazing! I have been struggling my entire pregnancy and this massage was not only relaxing but so calming. I absolutely loved the environment and the ladies are extremely nice! 100% would recommend"

Sierra J.

"Everyone was so WONDERFUL. Rachel answered multiple of my questions and was so patient with me the entire time through the phone and in person! She also helped me with scheduling ahead and prices- I was already convinced to go the membership route! It was my first time ever going to Onyx! Bobbi was amazing as well. She gave me a hydro facial and sat with me to listen to my concerns/skin problems while giving me advice and options in services that could help me. It was so relaxing and my skin is already glowing."

Tyree R.

"Robin Hall is phenomenal. Her attention to detail, care and thoughtfulness, effortless display of education allows me to completely trust her with my lips and service. I admire her for ensuring safety and prioritizing her best interest in the client and clients health. She did a perfect job on my lips. Thanks Robin!"
