A Medical Spa with Purpose

Our Story
PI Aesthetics was founded in 2022 by Thoa Fenton DNP, inspired by her experiences as a hospitalist, mother, and community advocate. Through years of caring for acutely ill patients she witnessed firsthand how stress, burnout, and self-neglect affect both physical and mental wellbeing.
Her sense of purpose deepened while serving on the front lines during the COVID-19 pandemic, where she experienced the transformative power of community support during an unprecedented crisis. Those experiences shaped a belief that true wellness extends beyond the absence of illness and must include self-care, confidence, and personal empowerment.
Federico Fenton MD MBA joined as co-owner shortly after, bringing clinical expertise in aesthetic medicine, advanced ultrasound training, and a background in business rooted in the belief that companies exist to create value for their patients, their team, and their community, not just their bottom line. Together they built PI Aesthetics into a practice committed to helping patients feel genuinely confident and empowered in their lives, while supporting their community in meaningful ways.

Our Approach to Aesthetic Medicine

Natural Looking Results
We believe good aesthetic treatments should enhance your natural features, not change them. This requires understanding your individual anatomy, facial proportions, movement patterns, goals, and what makes you look like you. It also requires a level of artistry that goes beyond technical knowledge, the ability to see proportion, balance, and harmony, and translate that into results that feel completely like you. Natural results are part of the clinical standard we have built our entire practice around, and that standard requires knowing not just where to treat and by how much, but also when to stop.

Beyond the Mirror
A great aesthetic outcome is only meaningful when it translates into something real in your life that goes beyond your physical appearance. We measure true success not by how you look after a treatment, but by how you feel, and what that unlocks in your life. That means something different to every person who walks through our doors. For some it is showing up to an important moment with confidence that was always there but now feels fully accessible. For others it is feeling more at ease in social interactions, or finally asking for the raise they deserve, or simply feeling like the outside reflects the person they have always known themselves to be. Those are the moments that matter most to us. That is when we know we have reached the outcome we were truly working toward. Every consultation, every treatment plan, and every follow up visit is guided by this mindset. This is why our tagline is Be Empowered. Be You.

The Training Behind the Care
Aesthetic medicine is an industry without a universal or national standard of medical training. This stands in stark contrast to most areas of medicine, where training is highly regulated and standardized, from training program requirements to licensures, board certifications, and continuing education development. In aesthetic medicine no such standard exists, and the gap between providers in terms of training, expertise, and clinical judgment can be significant. At PI Aesthetics, we believe this standard matters, and we hold ourselves to a level of clinical rigor, ongoing education, and evidence-based practice that reflects that belief. We are constantly seeking advanced training opportunities and investing significant time and effort to stay at the forefront of our field, because we believe that is what our patients deserve.
One concrete expression of that commitment is our use of ultrasound guidance for filler treatments and filler dissolution procedures. Ultrasound is a powerful tool, but its value depends entirely on the skill and training of the person using it. Interpreting what you see beneath the skin in real time, understanding the anatomy, and making precise clinical decisions based on that information requires advanced expertise that goes well beyond simply having the equipment available. Our doctors have invested years in developing that expertise, including teaching ultrasound techniques to other medical providers.

Relationships Over Transactions
The way we measure success at PI Aesthetics is not by how many patients we see in a day. It is by how well we know, understand, and take care of the ones we see. Understanding your history, your goals, and how your needs evolve over time allows us to provide genuinely personalized guidance. It also means being honest with you at every visit, even when the honest answer is that no treatment is needed right now. That kind of relationship is the standard we hold ourselves to every single day.

A Business With a Bigger Purpose
PI Aesthetics was built on the conviction that the work we do can create meaningful change, not just in the lives of our patients but in the community we call home. We actively seek to deepen our community ties and support organizations focused on mental health, self-esteem, and the well-being of those who need support most. We believe small businesses have a unique opportunity to show up for their communities in ways that larger institutions cannot, and we take that opportunity seriously. One example of this is our partnership with Domestic Violence Services of Snohomish County, an organization that works to rebuild confidence, safety, and a sense of self for those who need it most, values that align deeply with our own mission.
