Our Story

Sierra Miranda, RPN is the founder of Mia Medical Aesthetics, a medical aesthetics clinic located inside Mia Bella Suites on Upper Wellington in Hamilton, Ontario. As a Registered Practical Nurse, Medical Aesthetician, and Master Lash Artist, Sierra has been part of the aesthetics industry since 2019 and opened Mia Medical Aesthetics in 2020.

Sierra specializes in creating natural, timeless results that enhance each client’s unique features while maintaining balance, harmony, and long-term skin health. Her approach is deeply client-centred, focusing on individual goals, facial anatomy, and safe, healthy practices to deliver results that are both realistic and transformative.

What truly sets Sierra’s work apart is her commitment to education, safety, and personalization. Every treatment is thoughtfully planned with the client’s lifestyle in mind—ensuring results are not only beautiful, but easy to maintain and aligned with how clients live their everyday lives. Her clients leave feeling happy, confident, and excited to return, considering their treatments an investment in themselves rather than a routine appointment.

Mia Medical Aesthetics primarily serves clients seeking natural yet noticeable enhancements—results that simplify their beauty routines while boosting confidence and allowing them to show up more effortlessly in their lives. Sierra’s core values are rooted in health, safety, and long-term care, with an emphasis on enhancing natural beauty rather than changing it.

Inspired by the way aesthetic treatments bring out the best in people, Sierra believes that when you look good, you feel good—and when you feel good, you do good. This philosophy is reflected not only in her work, but in the clinic itself. Designed with girly, pink, chic, and luxe elements, the space radiates a youthful, feminine, and uplifting energy—creating an environment where every client feels comfortable, confident, and celebrated from the moment they walk in.
