I’ve been going to On the Side for over 10 years and have never had a single bad experience. I most often book massages and facials, and they are consistently exceptional. I see Ana every eight weeks for a facial, and she is truly amazing. Not only is she incredibly kind, but she’s also so knowledgeable and always knows exactly what my skin needs. I completely trust her expertise. The front desk manager, who has been there for as long as I can remember, is just as wonderful, always pleasant, welcoming, and ready to help with anything you need. They also have the cutest shop, offering everything from skincare products and candles to jewelry, clothing, and more. I often find myself stopping in just to pick up a gift! I truly cannot recommend this place enough.

5/5 stars for my prenatal massage at On the Side Day Spa. What a little hidden gem in Westfield! As a pregnant client, I was honestly nervous about finding a place that truly understands prenatal care, and they were incredibly well equipped. From the supportive pillows and positioning to my therapist Ashley's knowledge and attention to comfort, I felt completely safe and cared for by professionals the entire time. The facilities are beautiful and luxurious, the changing room was spotless and well stocked, the robes were cozy, and the whole experience felt relaxing from start to finish. If you are pregnant and looking for a legitimate, professional prenatal massage, this is absolutely a place you can trust. I will definitely be back!

Mariana was amazing! She is very knowledgeable at what she does and took the time to explain everything step by step, which made me feel completely comfortable and confident in her care. She’s gentle, professional, and truly attentive to your skin’s needs. You can tell she genuinely cares about her clients and wants the best results for them. I left feeling refreshed, glowing, and already looking forward to my next appointment. Highly recommend her!

★★★★★ 5.0 Corbiey Ouellette · Jan 2026

This was my first time getting any kind of spa treatment. I got the man’s day off package as a gift which included a 90 minute deep tissue massage and a sports pedicure. This is not something normally in my comfort zone and I was actually nervous. Allison was my masseuse and within 10 minutes. I felt like she was a family friend. It was not awkward and she’s very good at what she does. I felt relaxed and comfortable. Flor Did my pedicure and it was the same thing she was very good and helped me to feel relaxed. The rest of the staff works overtime to make sure that Experience. The atmosphere is incredible. Truly, a lot of effort is put into giving their customers a great experience and I’m already looking forward to my next visit. Piece of advice don’t be nervous and if you think this is s

A very relaxing experience even with a lot of customers which speaks volumes in itself. It’s a very large spa with many rooms in a calming environment. The essential oils they use smell wonderful. I had a pedicure, facial and massage. All excellent. I highly recommend this place.
