About La Ru Medical Spa

Our Story

La Ru Medical Spa was created with a simple goal: to bring clinical-grade, results-focused aesthetic care to Mammoth Lakes — whether in our office or your own special location. Our vision blends medical expertise with the refined touch of artistry — helping you look refreshed, balanced, and naturally radiant. As a long-time Mammoth local, DeAnna has her family roots in this community. La Ru was built for the people who live, work, play, and thrive in the Eastern Sierra — offering high-quality aesthetic treatments without leaving the mountains we love.

Our Philosophy

We believe that aesthetic medicine should elevate — not change — your natural features. Every treatment is tailored with intention, blending clinical precision with an artistic eye to achieve subtle, harmonious, confidence-building results.

The Story Behind the Name

La from Lola. Ru from Rexy Ru.

Lola and Rex — the inspiration behind La Ru Medical Spa

Lola & Rex — forever the heart of La Ru

La Ru was born from love — and a little bit of dog hair.

Lola and Rex — better known as Rexy Ru — are the beloved Boston Terriers of DeAnna and her family. When Lola passed away, her memory became the foundation of something lasting. La from Lola. Ru from Rexy Ru. And just like that, a name that means something real was born.

They were the kind of companions that make every hard day easier and every good day better. It felt right to carry them forward into something meaningful — a practice built on care, connection, and showing up for the people and things you love.
