About Us

Pekin Lab has been a family owned independent pharmacy located in Pekin, Illinois since 1949. Current owners Mark and Lea Ann Probasco are the third family to own and operate the business. We offer a variety of services to the community: prescriptions, over-the-counter medications, home oxygen, home medical equipment and free delivery just to name a few.

The owners of Pekin Lab are Mark and Lea Ann Probasco. Mark came to work at the Lab in 1996. A few years later he became part owner. Now in 2012 he has taken over full ownership of the Lab. Mark is a lifelong resident of the area. He attended Bradley University out of high school before transferring to St. Louis College of Pharmacy. Mark graduated from STLCOP in 1995.

Lea Ann is a graduate of Butler University. She began her career as a pharmacist in 1991 at an area hospital. Lea Ann joined Mark at the Lab full time in 2012. You won’t see her too often behind the counter in the pharmacy. Most of her time is spent in her office taking care of the business side of the pharmacy. You might also see her with her two young “assistants.” Mark and Lea Ann’s daughters. When not in school the girls hang out in a basement office and try to help out. If we need an art project done or a toy tested that is their specialty.
