I am SO happy we have a space like this in McAllen! Everything about The One Med Spa is amazing from ALL the people who work there, the style of the place, the procedures they offer, the results, etc.! It was my first time here and my first time ever getting Botox so I was doubly nervous. The minute I walked in I was greeted warmly by numerous people and immediately felt more at ease. Once I went in to get the procedure the nerves kicked back up because I had no idea what to expect…but Crystal was an angel! She made me feel so relaxed with how knowledgeable she was with everything, how thoroughly she explained it all and by how comfortable she was in her element. I HIGHLY recommend for everyone and anyone to visit The One Med Spa and experience the beauty that it is.

Matthew Morales, Owner of Quiet Mind Yoga Studio

I’ve known Crystal for 20+ years and she has always had a sharp eye for detail and it shows in all that she does. Maintaining natural results has always been so important to me and I love that Crystal and Dr. V. always give me honest feedback as to what I should be doing to maintain the natural results I want. I refer all my friends and family who are looking for the best and I’m proud to call myself a lifelong client and friend.

Ginna Mares – Owner of The Dry Room

“I started coming to The One Med Spa around 3 years ago and I can’t imagine now going anywhere else for my botox and filler maintenance. The spa is impeccable, their staff makes you feel special from the moment you arrive and during my treatments I know I am in the best hands! My results are always natural and I absolutely love the owners and entire staff!”

Perla Montemayor, Former TV anchor for Univision


I had the BEST experience I could ask for at The One Med Spa. Crystal was incredible, she thouroughly explained what the treatment entailed and educated me on the process and the results I will get. She made me feel completely at ease and I loved how detail oriented she was. I am in love with my results and will not let anyone else touch my face again. I highly recommend Crystal and the entire staff at The One Med Spa. I can’t wait to go back.

One of my favorite things about The One Med Spa is that Dr. V and Crystal are husband and wife team. They know exactly what you need just to accentuate your beauty and all of your natural features. So if you haven’t stopped by to check them out please do! You’ll look your best guaranteed.

I’m always impressed by the amazing customer service at The One Medspa! The entire staff is friendly and welcoming. I went recently to get a mini cheek pop by NP Audrey and I felt totally at ease! She made the experience comfortable and was very gentle with me. I’m very happy with the natural cheek pop I got! I was nervous it would look to obvious but she did the perfect amount! Thanks Audrey!!

I love coming to The One Med Spa because their customer service is impeccable! Whenever I come in for a facial or to touch up my Dysport,... I’m greeted warmly by the bubbly and friendly staff. In the past it’s usually been Zeke, the manager, but they now have new staff who are just as wonderful and friendly. Everyone is so attentive in making sure I’m comfortable while waiting to go into my appointments.Audrey is fantastic with her injections and won’t ever recommend anything not needed. If I’m interested in a service that won’t necessarily benefit me, she’ll tell me. I trust her abilities and her judgment which is another reason that keeps me coming back.Felicia is my go-to gal for my monthly facials and she always does an amazing job. I enjoy my appointments with her as I can relax while we laugh and catch up.If you’re interested in getting cosmetic treatments for your self care routines, I highly recommend you come to The One Med Spa. You won’t want to go anywhere else!read more

My experience at the One Med Spa has been amazing from start to finish every single visit. The staff are all extremely helpful and polite... from the moment they first greet you, and booking appointments is always such a quick and easy process. I've received botox treatments in a few different areas with Audrey and could not be more pleased with the results or with the service I received! I am always impressed with the professionalism of the staff and cannot recommend them or their services more

Love The One Med SPA! After months of searching, I found a place where I felt welcomed and comfortable. When I found them on Instagram, I... loved how the information is easy to find. The booking experience was fast and easy. When I first walked in, I felt welcomed. They treated me as if I had been a client for many years. Everyone, and I mean everyone is friendly and knowledgeable of the services they provide. I went back for my second time, and the quality of service was just as exceptional as the first time. I am extremely happy with my results, and happy I found The One Med more
