Patient Reviews for Heather Mast

“I’m always nervous trying a new spot for Dysport or Botox but Viva Day Spa put my nerves at ease and did a great job! Heather was outstanding! She was extremely intelligent and definitely knew her stuff! I was very happy with the results of the service she provided and she even recommended some treatments for me to try in the future. The only downside to Viva is it tends to be a little pricier than most places but with that you get top quality so I think it’s worth it!”— Jaime S. | Yelp (April 2023)

“I always have the best experiences at Viva! I recently started seeing Heather for my Dysport and I am blown away by her attention to detail and the wealth of information she is able to give me if I have any questions. I’ve always been worried about my eyebrows after injections and she took my concerns and helped make sure I was completely happy with my results.” — Allison W. | Yelp (March 2023)

Jamie did a chemical peel and some ipl! She is the sweetest person. So knowledgeable. I also just saw Heather another amazing knowledgeable provider. She did my Botox and dissolved some old lip filler. I already have my return visit. Viva is lucky to have these ladies!!!” — Shannon W. | Yelp (March 2023)
