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!
