I couldn't find any specific information about a nonprofit organization named "Shay's Wellness Center" with the EIN 274620098. However, there is a for-profit health and wellness center called Shay Wellness in the Memphis area, which is not a nonprofit. There are also other organizations with similar names, such as Shay's Warriors, which is a nonprofit focused on cancer survivorship. Without more specific details, it's difficult to create an accurate Wikipedia-style article about "Shay's Wellness Center" as a nonprofit.

If you meant to inquire about the for-profit Shay Wellness or the nonprofit Shay's Warriors, I could provide information on those organizations. However, for "Shay's Wellness Center" as described, there is insufficient information to proceed.
