From Our Clients

“My experience at Allegro MedSpa was wonderful! Kelsey performed my procedures that day, and I could not have felt more reassured that I was making the right choices to meet my specific needs and desires. Her experience quelled any anxiety that crept up. I had complete peace trusting her suggestions and advice for not only treatment now but beneficial procedures in the future.😀Kelsey was patient, engaged, generous and made me feel like I was the most important person in her life for the time I was with her! I will absolutely ask for Kelsey again in the future!”


“I was at Allegro for some Voluma in my cheeks. Kelsey was great about discussing what I wanted and suggested additional Juvéderm for some areas that have been bothering me. I told her I bruise easily, and she kept icing my face after she injected each area. I’ve never had anyone take such care to reduce bruising. My appointment was yesterday and yes, I have bruising, but I can’t imagine how much worse I would look if Kelsey hadn’t taken such time and care with me. I can’t wait to see how great I look once this bruising goes away! Thank you Kelsey!”



“First let me say, absolutely amazing staff! I have been here twice, first time for a skin consultation and skin care routine. Came away with a skin care program that suited my needs as well as a friendly consultation that made me feel so comfortable. (I rarely go anywhere without my makeup on, but everyone made me feel “normal” and beautiful and accepted for me) My second time I visited the MedSpa, (along with my Aunt) I met with Kelsey! And let me say…loud and absolutely clear!…..She is truly awesome! Kind….gentle…down to Earth…..professional and very informative! This was my first time looking into any type of “refresher”…..and so naturally I had some anxiety about what I should and shouldn’t do. Kelsey, was sooooo patient and kind and helped me (and my Aunt) with my/our decisions…as well as what was appropriate for me and my needs. SO thankful for her advice and wisdom! Absolute hands down….I had such a wonderful experience! Thank you Allegro MedSpa!….Oh!..and the lovely girls at the desk?…All smiles and treated me like family. You guys made my nerves turn into excitement and joy! I will definitely be back again. Looking forward to it!”
