Theresa Harmanen | Co-founder and Yoga facilitator

Theresa Harmanen | Co-founder and Yoga facilitator

She has practiced yoga for almost 20 years but her interest in energetics, movement and the spiritual realm has been with her since a young age, influenced by her father who was active in bodywork and massage. She has a strong creative side and a deep love and respect for Mother Nature and often draws inspiration from that in her yoga. Besides studio classes and corporate classes, Theresa is also available for private sessions.


Theresa is a certified yoga teacher (RYT 200 hours) in Samayoga – a holistic yoga form inspired by traditional hatha yoga with influences of Qigong, the chinese five elements, flow style postures, pranayama (breathing practice), mantra, ayurveda, Vedanta, and meditation. Theresa is also trained in Embodied style Yin/Yang Yoga (100 hrs continuing education CE) as well as Pre- and Postnatal yoga (50 hrs continuing education CE).


She considers her yoga mat her sacred island and every time she steps on the mat she arrives back home. Her teaching is soft and layered but powerful. Topics she often returns to are moon cycles and life transitions, the innate female strength and intuition, gratitude practices, and how to easily take yoga off the mat and into your life.


When not on the yoga mat, Theresa loves spending time in nature with her husband and 2.5 yr old daughter. She also loves traveling, resetting by and in the water, learning (the forever student!) and reading about yoga, health and creativity, as well as diving deep into her design projects.

Claudia Menger | Co-founder and Yoga facilitator

Claudia Menger | Co-founder and Yoga facilitator

Claudia found yoga in her early twenties, in Amsterdam, and although that first time on the mat felt so different from everything she had done before, she fell in love and kept coming back to that small studio facing the canals. A one-year world trip gave her the opportunity to practice with teachers around the world, and when she moved to Oslo she knew it was time to start sharing her love for yoga and the lessons she had learned along the way, by teaching classes.


Claudia is educated in traditional Hatha Yoga (200 hr), as well as Yin (50 hr), Vinyasa Flow (50 hr), Mother/Baby yoga (70 hr), Prenatal yoga (50 hr) and Restorative yoga + yoga Nidra (25 hr), and Fertility yoga (40 hr). Her teaching journey started with studio classes in hatha, yin and vinyasa yoga, as well as corporate yoga classes. Then came a long fertility journey, a difficult pregnancy and a traumatic birth experience, which all helped her find her path to helping women navigate the big and small transitions in life, all through yoga. Currently, Claudia teaches studio classes and privates.


Yoga gives her energy and stillness, and her mat is where she always comes home. Her personal practice follows the moon and her cycles, making every session on her mat different from the previous one.


Claudia loves exploring Norway with her husband + 3-year old son, eating raw cake, traveling, and reading, reading, reading. Claudia is also a holistic health coach and Reiki practitioner.

Abigail teaches fertility yoga at Sanga Yoga.


Abigail found yoga in 2005 when a dance teacher suggested she take a yoga class to destress from working on her PhD. From her first class, she knew she had discovered something very special and vowed that one day she would train to be a yoga teacher. Many years later, Abigail is a certified yoga teacher (RYT 200 hours) in Vinyasa and Ayurveda. She is also trained in Yin yoga, Fertility yoga, and Yoga to support


For Abigail, yoga is her sanctuary: her place to go when life throws a curveball. Yoga helped her navigate fertility struggles, IVF, and cancer, and she now uses her experiences and training to support women walking similar paths.


She uses vinyasa, yin, and moving meditations to cultivate a balance between strength and flexibility, both physically and mentally. Her classes are interwoven with philosophy, anatomy, Ayurveda, and Chinese Medicine, and students can expect to find a calmer mind, a deeper breath, and a strengthened connection with their higher selves.

Abigail has a PhD in geophysics, and her love of science translates to
a deep-rooted interest in the physics of yoga. She has a passion for
anatomy and alignment, and her background in dance brings a
playfulness to her yoga practice.
