The Ideal Locale for Group Celebrations, Retreats and More…

Osmosis is open to host groups of 6-36 for Spa Celebrations that honor any social occasion. In addition to a complete menu of rejuvenating spa treatments that focus on vitality and well-being, Osmosis offers a holistic mind/body/spirit experience that is totally unique and transformational.

Guests who participate in the special Spa Celebrations, mix and mingle as they flow from one relaxing spa service to the next, sampling each of our services with the highly personalized care of your dedicated staff. You and your guests will enjoy the unique properties of our Cedar Enzyme Bath with Japanese tea service, intuitive massages performed by the highly skilled touch of our massage therapy team and a luxurious aromatherapy skin care session featuring organic French botanicals considered among the finest in the industry along with a consultation from our experienced Estheticians. Afterwards, partake in an exquisite lunch of seasonal local organic cuisine.

Embraced by the coastal hills of Sonoma County, Osmosis’ sacred Asian-inspired environment naturally brings reflection and contemplation. The 5-½ acre property along Salmon Creek features a Japanese style meditation garden with soul-stirring rock gardens and bonsai trees surrounding a serene pond. Guests of the Spa Celebration receive a guided tour of the garden bringing deep meaning to the peaceful setting. Relaxation time in our Field of Hammocks along the banks of Salmon creek with a mind balancing Hemi-Sync® sound session completes the ultimate social relaxation experience.
