Pencol History
In 1925 PenCol Pharmacy opened its doors. The pharmacy was located at Pennsylvania and Colfax, hence, the name PenCol. PenCol became a staple for the neighborhood and eventually, customers came from all parts of Denver.
In 1973, Marshall Tobin, newly graduated from pharmacy school, opened his first pharmacy, Medisave pharmacy. In 1985, Marshall merged Medisave with Pencol and the pharmacies became PenCol Medisave Pharmacy. He then took the pharmacy into what was to become the future – compounding individualized/specialized medications.
Compounding is making prescription drugs the “old-fashion” way – from scratch, mixing the ingredients by hand so that each patient’s prescription is custom made to fit their specific, individual needs.
When Pencol moved to its current location, Marshall made one final change to the pharmacy, he re-named it Pencol Compounding Pharmacy. Pencol specializes in:
- BHRT – Bio-Identical Hormone Replacement Therapy
- Pain Medications
- Sterile Preparations
- Environmental medications
- Dermatology
- Veterinary medicines
- Specialized dental formulations
- Children’s medications
For over 40 years Marshall and the staff at Pencol have been proud to serve Denver, Colorado and other cities around the country as a premier compounding pharmacy. At Pencol, patients always have, and always will, come first.
