  • As we plan for the May Osesshin, the Tahoma staff is working to organize as safe a practice period as possible.  The Covid situation is quite fluid.  We are following the Washington State regulations and will continuously update our policies to conform.  We are hopeful that we will be able to conduct our May 2023 Osesshin but recognize that our plans, as well as the dates, may need to change suddenly and without notice.  If you are purchasing airline tickets please be prepared to cancel your reservations.
  • We recommend that persons who are immunocompromised or have chronic medical issues not attend this practice period.
  • There may be a waitlist for this Osesshin.  Those on the waitlist will be contacted immediately as spaces become available.

Thank you,
