How would I create a query, that pulls only 1 customer name from the customer table per account?

Tables

AccountTable
AccountNumber (PK)
Address
OtherInfo, etc...

CustomerTable
AccountNumber
FullName

If I do a left, inner, or right join, it will still get the incorrect number of records.

For instance.

Account table has 2 accounts.

1, 123 main street
2, 443 apple ave

Customer has 3 names

1, John
1, Jane
2, Bob

The returned results would be

1, 123 main street, John
1, 123 main street, Jane
2, 443 apple ave, Bob

How do I make it pick only 1 customer name, so that I am not duplicating address information?
