HEAR FROM OUR CLIENTS

“I appreciate the care and time Allegro Medspa takes to provide me with the information I need when I want to introduce a new product or procedure to my routine. I make informed decisions via their consultation process. They take the time to explain the process, expected outcome, and cost in a way that allows me to consider my options. I never feel pressured and always feel as if they have my long-term health and success in mind.” 

–Annalise D., Santa Rosa, CA, medspa patient.

“Allegra MedSpa makes you feel welcome from the get-go. The staff is professional and puts one at ease the minute you walk in. Your needs are met with quality care and results. Putting you first with their range of knowledge and skills is what they are all about. I encourage anyone who wants to make a self-improvement to pick up the phone and make an appointment. You won't regret it. I sure haven't.”

–Kyra N., Santa Rosa, CA, medspa patient.

“I started my laser hair removal process with Diana at Allegro MedSpa, and I am so pleased with the result! After only 3 treatments, I’m seeing major hair reduction on my face, legs, and underarms. I can’t wait to see the final result after 6 treatments! I’m, above all, so glad this procedure is pain-free (I’ve had very painful laser hair removal in the past.) If you’re considering it, I definitely recommend it! Make sure to book with Diana! She is so detail-oriented and makes sure she gets every little hair!”

–Ayaka J., Santa Rosa, CA, laser hair reduction patient.

“I had a great experience at Allegro MedSpa of Santa Rosa. The staff were all very friendly, and Karen, who did my injections, was outstanding! Karen took her time to let me know her recommendations regarding filler and Botox. I went with her recommendations for injection locations, and I am very happy I did! Karen really has an eye for what she does, and I will definitely be seeing her for future injections.” 

–Erica A., Santa Rosa, CA, Botox and filler patient.

“Allegro MedSpa is one of those places you stumble upon and instantly know you went to the right place! EVERYONE is so warm and friendly. I instantly knew I was in great hands after my first HydraFacial with Jenn. She is so knowledgeable and truly took her time examining my skin and treating it with exactly what it needed. She also helped set me up with a daily skincare routine that has completely changed my skin for the better…Absolutely recommend getting dermaplane too. You’ll thank me after.”

–Nicole P., Santa Rosa, CA, HydraFacial, skincare, and dermaplane patient.

“OMG, ok, well being a 270 lb ex-football player, I have never taken the time or even thought of taking care of my face, so my spouse talked me into going here and getting a HydraFacial. I totally fell in love with it and purchased the membership, which is WELL, WELL, worth it, but I absolutely love going in every month! The staff is so awesome, friendly, and helpful!!! My face is healthy, and I love it!!!”

–Big Ref, Santa Rosa, CA, HydraFacial patient.

“Love my lips!! Kirstie is a talented NP and as gentle as one can be with a needle. 10/10 recommend.” 

–Lori N., Santa Rosa, CA, lip filler patient.

“Karen spent a lot of time addressing my concerns and coming up with a detailed plan to achieve my goals. She is extremely knowledgeable, professional, and did an amazing job on my filler.”

–M Lynn M., Santa Rosa, CA, dermal filler patient.
