​
How we do it
​​​
By offering a tailored approach designed to meet your specific needs:
-
When it comes to graduate student support, this might be as simple as a reading and returning edits on a single chapter of the dissertation, or it could be reading the entire paper and returning written suggestions followed by video conferences to workshop suggestions.
-
When it comes to agency support, this might be as simple as reviewing and advising on a handful of proposals following solicitation for a study, or it could mean reviewing completed work(s) and holding in-depth conversations about quality of findings and implementation strategy.
