Founded by Kat McDonnell, Studio 108 Yoga & Pilates is built on decades of wellness, movement, and Seacoast community roots.

What began in 2018 as Kat teaching in her husband’s family farmhouse under the name Evergreen Yoga has steadily grown. In 2025, Kat opened Studio 108 in Stratham, combining classical yoga with state-of-the-art modern Reformer Pilates and heated classes. In September 2026, we expanded to Portsmouth’s West End to broaden our supportive network while keeping our core values firmly rooted.

Kat brings extensive certifications, including Hatha Yoga, the Barkan Method, Reformer Pilates, and Trauma-Informed Yoga, to a studio culture that deeply values both students and instructors.


Whether you’re stepping into our Stratham or West End locations for the first time or have practiced with us for years, Studio 108 is a welcoming space to build physical strength, emotional balance, and genuine connection.
