From the top of my head:

;with cteMembers as (select M.MemberID, O.OrgID, count(O.OrgID) over (partition by M.MemberID) as cntOrganizations
from Members M inner join Contacts C ON M.MemberID = C.MemberID inner join Organization O on C.OrgID = O.OrgID)

select cm.MemberID, stuff((select ',' + cm1.OrgID from cteMembers cm1 
where cm1.MemberID = cm.MemberID and cm1.cntOrganizations > 1
order by OrgID for XML PATH('')),1,1,'') as OrgIDs from cteMembers cm
where cm.cntOrganizations > 1
GROUP BY cm.MemberID
ORDER BY cm.MemberID
