Kahlil Mateus
Medical Assistant
What an experience to have Kahlil kick off our participation with the co-op program at Franklin’s own Tri-County Regional Vocational Tech High School! This young man has exceeded every expectation and has a very bright future. We simply could not have asked for a smarter, kinder, wiser, or harder-working medical assistant. We can’t wait to see where his dreams take him and are stoked to participate in his origin story.
