Client Success Stories

"Kristin is an incredibly knowledgeable and skilled injector. During our first visit, she listened intently as I shared my hopes for my results. She was then very thorough and detailed as she walked me through her plan. After two weeks, I was happy with my results, but she still offered for me to come back in for my first time client touch up appointment. I am SO happy I found Kristin and would highly recommend her. I will be going back and signing up for her membership soon!"

"Kristin is fabulous! She took me in for a walk in when I thought I had booked an appointment. She walked be through all the details pros/cons of a few of her services I was interested in. Did a quick baby dysport touch up and I was out the door. She kindly follows up after services to ensure all settled. Highly recommend and will definitely be back."

"Kristin is amazing! I’ve never had a better overall experience. From the moment I walked in she eased my nerves of receiving injectables and neurotoxins. I noticed real results right away and she followed up and has a true perfectionist eye. If you’re considering booking, don’t hesitate. This Med spa is truly a gem and exceeded all my expectations! Thank you Kristen!"

"Amazing service, had my lips done for the first time and could not have asked for a better experience. Kristin made me feel at ease and comfortable with the whole process. My lips look fabulous and most important no discomfort whatsoever."

"I love talking with Kristin about all things beauty! She listens to my concerns and always has great feedback, telling me not what I want to hear but always the truth. In that way, I know I am getting honest feedback, which is so important because aging can be so taboo and petty.. I leave her office feeling better then when I entered- and to me that’s the best sign of a positive experience!! As a mom of four, my schedule sometimes changes last minute and Kristin always tries to accommodate that, not only finding time for me, but being understanding as well. I could not recommend the “Lean and Lovely” Kristin more!! ❤️"

"Kristin is so lovely! I’ve followed Kristin on instagram for years and was really impressed with how she treated her patients, and how natural everyone looked. When I was ready to talk about Botox, I booked a consultation to discuss my areas of concern and her recommendations. She is very knowledgeable and happy to answer any/all questions. I had never done anything to my face beyond regular facials and she was so kind and let me decide on my own what I felt comfortable with without being pushy at all. Treatment included a complimentary follow-up to see how everything settled and touch up if needed. I can’t recommend Kristin enough. She takes so much pride in her work and you can tell she loves what she does."

She doesn’t over-do it and is always checking in after our appointments to make sure I get the desired results! I am so grateful for her and I have referred all my friends to her! Truly a gem!"
