Testimonials

Patients reviews

Patients describe Hana as knowledgeable, kind, and precise—valuing her educational approach and the natural results she consistently achieves. 

I rarely write reviews but this is just one of those times I felt I needed to. I was referred to wonderbar by a relative who had a great experience so I wanted to give it a try. I went for a consult where everything was explained in detail and all my questions were answered. I went forward with two treatments on my face. First off all the staff has been very friendly, helpful and knowledgeable. Hana did my procedures. She’s amazing and keeps you comfortable throughout. It’s quiet and private, a very nice environment. Booking is easy and you get a text reminder so no mistakes are made in schedules etc. I have only good things to say about the experience and plan on using more of their services in the future!

Nurse Hana is the BEST! Not only is she extremely knowledgeable and great at her job, but she really cares about her patients. She takes the time to understand your goals and explain your options. When I say “she takes the time” I really mean it. I’ve never felt rushed during any of my appointments.

I have been seeing Nurse Hana at the Wunderbar Med Spa within Korman Plastic Surgery for almost two years now, and I highly recommend seeing her! Right off the bat, she took the time to explain | the benefits of different treatments (I originally was seeking IPL) she shared with me all of the things we could do to achieve my desired results, and why. For example she talked about BBL and what that does and why it is a great start for a skincare journey (evening the tone of the face by reducing redness and removing brown spots). This was the first treatment aside from Botox that I started with her and since then have also done the PRP facials (“Vampire Facials”), as well as a few other things along the way…. She is always so good at what she does and I’m thrilled with my results. When I look back at photos from first seeing her to now, I can really tell how much improvement has been made, and it’s so exciting!! Also why I wouldn’t go to anyone else! | I also appreciate, when it comes to Botox, she is honest I’m not wanting to overdo it and completely freeze a face, she talks about why you want some motion for the health of your face, etc. and I think it says a lot that she doesn’t just try to inject a ton of units just because. She is very thoughtful in her approach, in wanting the best for her patients long term. Also, she is fun to talk to! I just adore her as well as the office staff! Gabriella is who I have been seeing lately and she is always so kind and welcoming, it’s always a wonderful experience!
