Show patients by login or user

dear friends

I have a proyect that i modify to use in a car workshop… i create a few users to acces the data. problem is that all users can see other users patients (all of them) and i want to show only patiens in their registry.

for example, this is admin patient list:

and this is a user patient list:

(due to new user i cant upload image, but is the same list in both users)

as you see, the list show all patients from other users…

can you help me??
if help requires money there is no problem.

best regards!
