What Our Patients Are Saying

"The staff at Cornerstone saved my life! And that isn't for dramatic effect. I have been a customer for a few years and pick up my prescriptions for some serious, but not so obvious problems. I recently went to the doctor for a checkup and he prescribed me a new medication for an anti-coagulant. John, Carlos, and Dolly know me, and knew the mix of medications I was on. They called my doctor and he immediately cancelled the script. Had I taken the medication I would've almost certainly bled to death. Thank you guys! I owe you one."


"My son Sam is severely autistic and blind. He can't swallow pills and he hates the taste of antibiotics, which he needed because he was really sick. John offered to make him a custom mix of medicine because he knew he could make it taste better. He called his colleagues up to figure out the best formula and after two tries he got the flavor just right, and Sam actually enjoyed 'medicine time'."


"Going to Cornerstone feels like a visit to your family's house. Everyone treats you so nice and they make sure that you get the best care. Delivery is no problem at all. John has the best employees... They greet you with a smile all the time. You'll be happy choosing Cornerstone I promise."


"At Cornerstone Pharmacy everyone is treated like family. John and his staff go above and beyond their customer's needs every day! At Cornerstone your health and well being is their #1 concern. Having a local pharmacy where the staff knows you by name is so rare these days, at Cornerstone everybody knows your name. Stamford is very lucky to have them."
