Reiki Treatment


Reiki is Japanese and stands for "universal/divine life force energy". It is an ancient energy healing technique that was rediscovered by Dr. Mikao Usui on his own healing journey in the late 1800s.

Reiki is non-invasive and balancing in nature. In a session, the practitioner channels Reiki in through their crown and out through their palms, onto the client - by either applying gentle touch or just hovering the hands above the body.


While Reiki promotes general wellness & relaxation, it also assists with reduction of stress and chronic pain, insomnia, support of the immune and endocrine systems, blood pressure regulation, and other ailments.

First session 90 minutes; follow-ups 60 or 90 minutes. Packages available.

We are all built differently and come to the mat with different needs - 

therefore, a "one size fits all" approach never works. I am convinced that yoga should be accessible to everyone, which is why I strive to remove barriers and diffuse intimidation that often keep one from starting a yoga practice in the first place.

My preferred style of yoga is Vinyasa, that I teach based on the client's needs: more vigorous or rather gentle and restorative.


By aligning movement and asana with breath, using the help of props, and introducing yogic philosophy to the client, yoga becomes a powerful tool that facilitates healing and growth.

Sessions last 60 or 90 minutes.

Ayurvedic Consultation

Ayurveda (Sanskrit for "life knowledge") is a 5,000 year old ancient healing system in the Vedic tradition of India and sister science to yoga.

During the intake, I will look at your tongue and take your pulses, as well as determine your current metabolic state with any imbalances (Vikruti) by asking questions (in person or with the help of a quiz).

The outcome: a tailored, individual therapeutic plan (chikitsa) that will help to create balance and give guidance on how to incorporate simple Ayurvedic tools into our daily western life.

First session is 90 minutes; follow-ups are 60 to 90 minutes in duration.

Intuitive Mentoring

Living in a time and place that is often egoic and disharmonious, especially to empaths and gentle & sensitive souls, one sometimes reaches a crossroads and looks for guidance.


Spiritual mentoring is a helpful tool to bring you back to a more harmonious path that is right for you, and in tune with nature and the sacred agreements that were made between your soul and the divine.


Mentoring is an investment in yourself, and can be done in person, or in the comfort of your own home, online via Skype or FaceTime, or over the phone.

Session are 60 minutes or longer, upon request.

Yoga Nidra 

Yoga Nidra is an ancient meditation & relaxation system that combines focus, meditation and visualization, bringing the practitioner into a state between wake and sleep. Brainwaves drop to uber-relaxing frequencies.

Over time and with a continuous practice, a tangible reduction in stress and tension can be achieved. Beyond that, a large number of scientific studies were conducted on the effects and benefits.

All in all, Yoga Nidra is a great modality for inexperienced practitioners, as it is practiced lying down in savasana (corps pose), which makes it so accessible.

Sessions are 60 minutes in duration.

Available in-person, online or pre-recorded.

Meditation - Pranayama

Meditation is a state of being where we can experience a deep awareness of self that allows and facilitates relaxation, healing and the building of overall resilience.
The gift of meditation is one of the biggest I have received, as over time I have achieved a higher level of concentration and focus, but also stability and a more relaxed attitude towards life.

Pranayama is Sanskrit for "to control/restrain breath/life force".


Controlling and redirecting the breath in new ways, made me unleash new powers, and helped me overcome and heal deeply embedded fears and phobias.

Sessions last 60 minutes.
