I've been coming to Julie for years. She is an expert at what she does. I trust her as she takes care of her clients. She is never pushy and only wants what is best for each client. Her work is incredible, she always answers all my questions, environment is safe and clean as well as she genuinely cares. I have friends that are looking for first time botox aswell as switching to a new aesthetician and she is a must go to! read more

Love KNMedspa! Had many micro-needling treatments with Kathy in the past which I will always recommend! Had my first RF micro needling treatment with Sarah the Venus Viva,I'm sold! I hate my turkey neck and have tried many creams and other treatments to tighten the skin with little to no change. One venus viva treatment (no down time!)has made a nocticeable difference and I feel so much more comfortable and confident. I can't wait to have my next 2 treatment to see the full result!!! read more

What a great experience I just had at KN Medspa with Julie Lambert, RN - she was truly amazing! She took time answering all my questions about my treatment and offered suggestions for my future ideas/treatments which I posed to her (which I desperately need) all with absolutely NO sales pitch whatsoever! The entire process was seamless and professional and Julie made me feel totally at ease, was extremely kind and positive. She did an amazing job and educated me on my skin's needs and I totally appreciated it and her! If you're looking for a quality, compassion educated professional, I could not recommend Julie enough!!! I would rate her: 10/10 read more

Julie is awesome!! She's very knowledgeable and does great work. She's a master at what she does!

KN Medspa is the best skin care and wellness spa I have ever experienced. Kathy and her team are top notch and I feel lounger everyone I leave! Would never go elsewhere and now traveling there from Maine. Totally worth the trip! read more

Kathy is the best! She knows exactly what you need and is always honest. She will fix and preserve your face from aging in the most natural looking way. read more

I can't say enough about Kathy Nash and her staff. I have had a few different services performed by her knowledgeable and caring staff. Kathy is a GENIUS with a needle. All of her injectable treatments are tastefully done and almost painless. I highly recommend trusting her to make you look and feel great... PS.. she's super nice too!! read more

Kathy Nash is the best ever!!! So professional and made my whole experience fun, special, and personalized. She performed Kybella on my double chin area and produced such a great result with minimal pain. Cannot recommend more! read more

I have had laser hair removal performed on my face for about 10 years now. What used to be a lawn of hair growth has been reduced to a few hairs now and then. After receiving treatments from the same place in Cambridge for many years, I decided to try somewhere new in my home town. KN MedSpa is located in a quaint South Natick historic building and has a boutiquey feel. The staff is friendly although I wouldn't describe them as "down to earth." However, I can not justify the cost of laser treatments here. For very significant hair removal elsewhere, I've always paid between $60-80 per session. Using the same machine and requiring far less time (15 mins), my session at KN MedSpa was $250. That's 3-4x more expensive! It probably works out to $10/15 per hair, which is outrageous. I have frequented Essentially Bare in Cambridge for the past 8 years. Their staff is equally knowledgeable and skilled, the office is in a medical office building and very bright and clean, and (using the same machine) I've had outstanding results for a fraction of the price of treatments at KN MedSpa. I will be returning to Essentially Bare and continuing to recommend it to my friends looking for a local laser hair removal center. It is worth the drive. I really wanted to love KN MedSpa but am quite disappointed. read more

" You look so pretty " my husband remarked when I returned home after my appointment with Tricia for eyelash extensions. "Your skin looks tighter" after 2 micro needing appointments with Kathy. Need I say more??? I think I will. I love this cozy spa. It is pretty and friendly with just the perfect amount of professionalism to inspire confidence without feeling off putting. Great products as well! read more

Kathy Nash is down to earth and knows her stuff. I had two sessions last spring to remove red broken capillaries and some sun damage and almost a year layer I still get complements. I have had rosacea since high school (25 years) and suffered with a flushed, red face because I thought laser treatments were too expensive or only for fancy people. As a master esthetician, I had tried every cream and lotion. I have sent many clients here and recommend without hesitation. A hidden gem. read more

The owner, Kathy, is so good. I started seeing her for her regenique facials after I had a nasty staph infection (MRSA) on my face. After that experience I was skeptical of anyone touching my face, but trusted her 100% because she is an RN and knew exactly what MRSA was and understood what I needed. That was in 2009. Since then I've seen her regularly for facials and dermaplaning and now microneedling. It is amazing. My best friend lives in LA but had Kathy do her lip injections because she felt getting it done in LA wouldn't look natural. She loves her lips- says Kathy is an medical practitioner but really more of an artist with injections and fillers. She knows exactly how to make everything look natural and not obvious so you don't look like some Real Housewives cast member. You look like yourself, when you were 28. Trisha now does my facials and a lot of the other treatments too, and she's also phenomenal. She's been with Kathy for years and has learned from the master ;) read more

The best facial I have ever gotten! See Tricia at KN MedSpa for instant, but lasting results. I have never been able to say before that I could see results from a facial treatment but honestly I leave feeling like my skin has been deep cleaned. I even love the cozy, but modern feel of the spa's decor! Love this place! read more

Why go under the knife when you have the great expertise of Kathy Nash and her med spa? She is a wizard at what she does and will find a way to rediscover your youth. Bravo. read more

After I got warm recommendation about Kathy from a friend I went to KN Madspa for a blackhead facial treatment. I came all the way although it is far from my home and was extremely disappointed. Trisha, who took care of me did superficially work, she kept talking very fast though I told her my English is not so good and I didn't understand what she did, I had allergic reaction to their wax which never happen to me before, they charged 125$ for 45 minutes (for a treatment that suppose to take an hour) and latter when I left a massage for Kathy to complain she never returned my call. I have to say that the place looks very nice and the administration worker was lovely but I will never go there again. read more

I recently had some laser treatments at KN Medspa and was overwhelmingly impressed with the results. I highly recommend their services and was astonished at how great my skin looked afterwards. Kathy listened to what I was looking for, and offered suggestions that were tailored to the specific needs of my skin. Very stylish and comfortable setting, and a staff that is both friendly and knowledgeable. Highly recommended. Great products also, I tried some Image moisturizer that I am in love with! read more

No place better for customized personal attention and transforming your skin. Kathy has set high standards for her staff and herself. They never try to "sell" you a service , but give you options and every one of them has a great impact on looking and feeling younger. Professional, serene, transformational. read more
