I am making the assumption that by Client you are referring to Accounts.
What is your Org Wide Default for Accounts? It should be Private. Now, keep in mind this means that while users with the same Role will not see each others Accounts, users with Roles above them will be able to see them (manager can see rep's Accounts but other rep cannot see rep's Accounts).
System Administrators are always going to see everything.
