Dr. Chaychi and her staff are absolutely incredible! From the moment I walked through the door they made me feel like a pampered princess. Dr. Chaychi really took her time explaining everything to me it made me feel so comfortable and educated. My results are even better than I imagined.

This place is a hidden gem! The staff is professional and friendly, and they have so many things to choose from. Janessa is amazing--she listens carefully, tailors treatments to your needs, and delivers incredible results. She is also insanely knowledgeable and talked through my desired results & treatment with me so I knew exactly what to expect. As someone who works in front of a camera, I need my treatments to look natural and subtle, and Janessa absolutely nailed it. Ask for Janessa, you'll love her!
