The Rev. Jeff Tindall of Carnegie Presbyterian Church said he has agonized with parishioners who have needed health care and couldn't get it. Some couldn't afford it, others lost a job that included health care benefits, still others were denied coverage due to the now-banned practice of insurers refusing to cover pre-existing medical conditions. So on a recent snowy Sunday morning, Rev. Tindall yielded his pulpit for a couple of minutes to Shannon McGee of the Allegheny Intermediate Unit -- a branch of the Pennsylvania Department of Education -- which has been helping educate local residents about how to enroll for coverage under the Affordable Care Act.
