Samuel Torres2024-07-20Trustindex verifies that the original source of the review is Google. Joanna has been my go to for a few years now. She knows what massage therapy is necessary based on what you may be feeling. From deep tissue, to cupping, and my most recent, the lymphatic drainage massage. If I could give 10 stars that’s when I’d be giving Day of Beauty spa. If you’re on the fence when it comes to making a decision on visiting let me be the one to push you over because you won’t regret it. Amy Tribbey2024-05-30Trustindex verifies that the original source of the review is Google. Joanna chose the perfect name for her spa. It is truly a Day of Beauty, from start to finish. The location and property is french farm like with beautiful flowers and plants everywhere and a lovely welcoming front porch. The ambiance and decor once inside is truly perfection. Her detail is impeccable, with so many pretty things to see and a fantastic attached shop full of the most unique and high quality gifts. It smells lovely with fresh grown flowers from her garden and tastes wonderful with a yummy cookie and tea in a very special fancy tea cup. All this is just to start! Jonanna herself is stunning, inside and out. She was so warm and welcoming to me, spent time chatting with me before and after my facial and even walked me to my car. It felt like I had known her forever, like a true friend. The facial itself was way beyond anything I have ever had. The table itself was warm and cozy and soft, and everything she did to my face felt and smelled wonderful. Her skill level is beyond compare, with incredible attention to every aspect necessary, ever detail. My skin felt and looked amazing when I left. With my whole heart I recommend making an appointment with Joanna and giving yourself the gift of her true Day of Beauty.
