Excellent service and an overall pleasant experience. Victoria was professional and knowledgeable. She proposed treatments addressing both my anesthetic and medical concerns.. I could not be happier with the results. Also, the Receptionist, Mattie, was pleasant and efficient. I look forward to future treatments.

Hayes Valley is the best! Kate did an incredible job with Dysport removing the wrinkles from my forehead, Sandra gave me great abs and glutes with Emsculpt, and Linda gave me my youthful facial structure back with Sculptra. These women are truly amazing. So glad that I found them!

I love Hayes Valley Medical and Esthetics! I've been coming for a while now for Botox and filler treatments. Linda is AMAZING! She knows just the right amount of product needed in all the right places to bring out my best facial features. I feel more handsome every time!!

The front desk staff are super sweet and helpful. They always ask exactly what I want and I never feel like I'm being 'upsold' or encouraged to do anything other than what I came in for. I would highly recommend HVME to anybody that is on the unsure about trying some of the services they offer. You won't be disappointed. Thank you!!

Diana at the front desk is so sweet, the medical assistant was amazing & personable and Kate who did my procedure is my favorite! As I walked out and met my husband, I told him how much I enjoy being there & what a good vibe Hayes has.

Sheila and Linda took great care of me and I look younger and vibrant.  I do not trust anyone else for injectables.  Linda is careful, thoughtful, and respectful of one’s budget. I have followed her from Marin into SF and I will continue to follow her where ever she practices.

I highly recommend Hayes Valley Medical & Esthetics!! All the front desk staff are warm, friendly and professional and Denise is the best for laser, she goes above to make you feel comfortable and at ease. Andrea is exceptional at explaining the services they offer. They are the best in SF in my opinion and I do my research!
