Ph.D.-ed philosophers vs Doctors of philosophy vs philosophy Ph.D.'s? Basically, I'm asking how to refer to a group of individuals who all have the same degree.

I'm referring to them in the third person, as in, "I work with a group of (x)".

let's just assume for purposes of the title, that all the individuals in said group actually have the literal job title "philosopher", and it is important to call attention to the fact that they have doctorates in (stand up) philosophy.

My inclination would be the first one, but in searching, that doesn't seem very common.

To expand, I'm writing my application essays for graduate school.  I work in a non-academic setting that still has a research focus, and I'm trying to briefly describe the organization in a way that would support the narrative I'm building, that working here has fostered my interest in research.

The organization is made up almost entirely of Ph.D. holders in largely the same field.  But naming one as a practitioner of that field does not by itself imply that they hold a Ph.D.  That's why saying "I work with a group of philosophers" doesn't convey the right message.
To expand upon @MattSamuel's comment, any/all of the following probably work:

I work with...


...a group of philosophy Ph.D.s
...a group of philosophers with Ph.D.s
...a group of doctors. Doctors of what you ask? Philosophy.
...a group of philosophy researchers (ed. note: tends to imply Ph.D.s, but not explicit)


The simplest option in my opinion? "This is Dr. X, Dr. Y, and Dr. Z. They all study philosophy."
