Yes please :-)

With respect to the 'Dr' title, though... You would only be able to call yourself 'Dr' if:

1) The courses that you are getting the certificates for are part of your enrollment in a PhD or PsyD program

AND

2) After you had finished them (plus your thesis) the degree would be conferred in a graduation ceremony. Whether you attend the ceremony or not you can't use the title legitimately until after that ceremony.

Outside the USA (e.g., in the UK, in Australasia) clinical psychology can be part of either a Masters Program or a PhD or PsyD program in a university setting. If a person does courses as part of a Masters degree then when the Masters degree is conferred they are still not allowed to use the title 'Dr'.

There are also other ways to get license to practice - but these other ways don't allow one to use the 'clinical psychologist' title or the 'Dr' title...
