Post Doctoral Fellows


In addition to Drs. Hansen and Watson-Perez, West Morris Psychological Associates employs Post-Doctoral Fellows. These highly-trained Post Docs have completed their doctorates in Psychology at American Psychological Association Accredited programs. Their training includes extensive coursework, research, teaching, and a full year clinical internship. In the state of New Jersey, graduates of these programs must then work for three years under the supervision of a Licensed Psychologist as they progress toward their own licensure. During this time, Post Doctoral Fellows hold a Temporary Permit to practice under supervision, issued by the New Jersey Board of Psychological Examiners.  


At West Morris Psychological Associates, we are highly selective in the Post Doctoral Fellows we hire.  Many clients find it beneficial to see a Post Doc because their fees are lower than the fees of our Licensed Psychologists.  Additionally, the quality of care is superb as they are highly supervised by our experienced Licensed Psychologists.


The New Jersey Board of Psychological Examiners has regulated that advertising Post Doctoral Fellows is not permitted. This is why you will not see our Post Docs on our website, nor will they be able to advertise in any way until they are fully licensed.
