I’m so happy that Nadja was my stylist! 12 out of 10 perfect! Super nice, very hospitable, AND MY HAIR LOOKS AMAZING! I’ve given her business cards to several friends! I will definitely be back!

Perfect morning at the spa! It was a birthday treat from my daughter....I enjoyed the Experience Room and the Salt Room. Both were very relaxing! Spotless facility and top notch staff.
— Heather B.
Amazing facilities, great services. Had a signature facial done and it was so relaxing and my skin glowed for days after.
— Kathryn O.
Great experience!! The staff was welcoming and the space is beautiful. Sasha, works in the spa and she performs my brow tweezing. She does a perfect job! She is the only one I trust to shape my brows! I’m always so pleased.
— Lauren D.
From day one of going into this spa I was greeted by Dave treated very special all of my needs were taken care of. The staff is professional, respectful and ensure that you have a wonderful time. I love feeling more relaxed than when I came in I so appreciate the staff taking that extra time to make sure that my needs were mad and that I was okay this is what service should look like 365 days out the year.
— Gloria W.
I received an incredible signature facial from Alina! She was so kind and knowledgeable, and she took the time to discuss my skin concerns with me. I felt so relaxed and rejuvenated after! Also, the facilities/amenities at this spa were fantastic. Overall very impressed and I’ll definitely be back!
