Posted on Crystal LaBathe Kassi at KÁLLOS Beauty Studio is absolutely fantastic, I can’t recommend her enough! She is amazing to work with, super thorough in how she explains each process and procedure and is an absolute pro in the industry with providing all the latest and greatest options along with all the know you need to make the right choice for you! I love the fact she keeps every individual clients goals and long term priorities in mind and builds a plan to achieve those over a period of time with the client, giving plenty of options along the way. I also love her down to earth style, she put me at ease right away and I trust her instincts and advice when I’m debating choices. She’s the best!Posted on Jennifer Goldfarb Kassi is super sweet and talented. I went to her for a consult and Dysport. My face looks natural and doesn’t feel tight. I can still show emotions while protecting my youth that I am desperately hanging on to. Highly recommend. She also carries great skincare like Plated.Posted on Christina Jones My First time ever having a procedure done to my face and everything turned out beautifully! I highly recommend!Posted on Kara Meyers Kassi is an absolute delight - she is sweet, kind, listened to me, explained everything and answered all questions I had, all while being very personable and putting me at ease. Her studio is a hidden gem, tucked away in a beatiful neighborhood in a stunning home where she's setup her private space. This was my first time seeing Kassi and I will absolutely be sticking with her. She did a perfect job on my injections and I was in and out in rapid time. She followed up a couple weeks later to make sure everything was ok. I highly recommend Kassi and KALLOS: A Beauty Studio!Posted on Jenna Jehowski Kassie's intentional and educational style is sure to get you the results you want! She is the most educated injector and facialist I have ever worked with. You will never go to anyone else once you see her!!Posted on Caitlin Rosencrantz Kassi is beyond amazing! She has the most down to earth personality. You instantly feel at home as soon as you walk in. Her expertise in this field is top tier. She is not there to make money, she genuinely cares about your experience and results. She’s honest about what treatments may work better than others and she is a perfectionist about her work. Not only is she amazing in clinic, she does not forget about you once you leave. She checks in multiple times on the day of treatment and frequently after. She wants the patient to be happy with their experience and is always available to answer any and all questions you may have. Truly, the best experience!!Posted on Marissa Anderer What a Gem!! I worried I wouldn't find an injector that I clicked with when Moving from Los Angeles to North Carolina. I've searched and almost lost hope until stumbling across Kallos on social media. I have never felt so welcomed and comfortable before and genuinely feel Kassi had my best interest in mind when going over options with me due to asymmetry! I couldn't be happier with my results here at Kallos and I will stick with Kassi for as long as she'll have me! lolPosted on Shauntavia Jones I loved Mrs Kassi she fulfilled my lip expectations, will be coming backPosted on Koryeah Dwanyen Kassi at Kallos is an absolute gem! For the past five years, she's been instrumental in helping me achieve my skincare goals. Kassi takes a natural approach, and her passion for what she does truly shines through in every visit. She's knowledgeable and always makes me feel comfortable and understood. You can tell how much she cares about her clients' happiness, and I always leave my appointments feeling refreshed and confident.
