Office Visit

"I love this med spa ! My style is very simple, jeans and no makeup. This place is for everyone.  I've seen Wendy (receptionist) greet patients with a warm smile and an approachable personality. She's emailed the doctors on more than one occasion  to get information I wanted. I've been a "fan" of this spa since they opened. Danielle (aesthetician) has always treated me with kindness and honesty. I'm a regular with her for Vela Shape, great for circulation and skin tone. I've also tried Ulthera ( for my face ) It's somewhat uncomfortable but worth it. She talked me through the procedure and described the process as she went along. Daniele has also given me a few facials and finished with a great eyebrow wax. I asked what products she would recommend for me. She advised me of products she knew would be conducive to my style.( not too much) I use a facial wash, sunscreen, vitamin C serum, lotion for my rosacea and I just started using a Retin A product for patients with rosacea. (I'll let everyone know how it works)The spa also has Cool Sculpting. Clients and staff who have had it done are thrilled with the results. The doctors didn't feel I was a candidate due to a minor medical condition .Dr. Canales and Dr. Furnas are always aware of their patients in the spa. I always feel safe and reassured with the procedures I've had done. I've also had great IPL treatments ( for rosacea) with Lisa (RN). Lastly, an added benefit of going to Allegro is learning of new procedures and surgeries from the spa and the doctors. Whew .....and that's what I know and experienced at Allegro Medspa"



"As a patient of Dr. Canales, and a background in aesthetics, it is with great pleasure that I write this review. I come here to see Joy for Juvederm and Botox. Each and every time I have minimal bleeding/swelling/bruising. She is honest about what is needed, and is confident in her work-- as am I. I have been to many other cosmetic surgery offices to receive treatments and left with heavy brows from poor placement, and uneven lips. Joy has even corrected a botched job I had in SF a year ago. She's amazing and I highly recommend her."



"I recently got the breast augmentation I've been wanting for years! Dr. Canales and his staff are so welcoming and sweet. I was so nervous right before surgery and naturally, I cried. The nurses wiped my tears and rubbed my head to calm me down before I fell asleep. I've never felt so cared for. Megan is the biggest sweetheart and Dr. Canales is extremely professional and kind. I look forward to the 4hr drive for my appointments. I would highly recommend The Allegro MedSpa for all of your needs."
