Our Approach
At Portico Longevity and Primary Care, we are dedicated to helping you slow down life, live longer, and look and feel younger.
As a private medical and esthetics practice, we offer a range of services to help you be your best self.
From in-depth longevity consultations and nutritional counseling, to sports medicine and hormone testing, we are here to maximize your health. As part of our commitment to personalized care, we also offer direct primary care—giving you consistent access to your provider, same-day or next-day appointments, and ongoing support without the complications of insurance.
Our rejuvenating skincare, laser, microneedling, and Botox treatments go beyond the surface, because beauty is truly more than skin deep. Imagine experiencing all of this in a warm and welcoming spa-like atmosphere.
Our facility features an infrared sauna, cold plunge pool, copper tub mineral bath soaks, steam room, and Vichy shower for you to relax and enjoy. We believe that no one should dread going to the doctor, which is why we prioritize personalized care and attention.
Our team will get to know you personally and make you feel at home. You can even unwind in our garden and savor a cup of tea or a glass of artesian spring water.
OUR PORTICO
Vanessa Mendes RMT
Vanessa is a registered massage therapist and certified yoga instructor who has been practicing for over 20 years. In the last 5 years, she has added scalar energy healing to her practice, bringing to Charleston the highly advanced Rasha system. The Rasha is a consciousness-coherence technology that includes brain optimization, chakra harmonization, psycho-emotional transmutation & relaxation. Vanessa’s unique form of healing is just another way of working with the body, mind, and spirit to both heal and prevent illness.
Vanessa’s approach to healing the nervous system to release stress living in our bodies allows us to offer specialized therapies for those needing a reset. She works mainly out of our James Island location and offers massage, yoga, sound bath therapy, in addition to Rasha scalar plasma energy therapy, Bio Well energy scans, and brain tap therapy sessions. Additionally, she teaches private cooking lessons and is helping us set up our first Portico garden!
Katie St Clair
Senior Aesthetician
Katie began her career in 2016 as a licensed esthetician, where she developed a passion for skincare and a deep desire to help others feel confident in their skin. In 2021, she expanded her expertise by becoming a licensed massage therapist, combining her knowledge of skin care with the healing benefits of therapeutic touch. Through her travels to Europe and Asia, Katie further advanced her career by specializing in advanced facials and becoming certified in Thai yoga massage.
Katie’s diverse background in both esthetics, massage therapy and sound healing allows her to offer a holistic approach to wellness. She is committed to continual education and strives to stay at the forefront of her field to provide the best possible care for her clients.

By enhancing her clients’ well-being, she feels it helps them become kinder and happier, and in turn, spread that positivity to those around them. She is passionate about creating an environment where every client feels truly cared for and empowered.
When she’s not at Portico, Katie enjoys traveling, surfing, paddleboarding, yoga, sound healing, and taking art classes—though she admits she's not particularly good at it, she enjoys the process!
