If you use Oracle you can create a PL/SQL function you can use in your query that accepts an organization_id as input, and returns the first name of all employees belonging to that org as a string. For example:-

select
   o.org_id,
   o.org_address,
   o.org_otherdetails,
   org_employees( o.org_id ) as org_employees
from
   organization o
