Welcome To Cornerstone Pharmacy

We opened our doors in June of 2017 and are excited to serve the pharmacy needs of the Coachella Valley. As a team, we have a combined experience in community pharmacy of over 70 years. We take pride in being an integral part of the community and treat our patrons with the utmost respect and professionalism. Our pharmacists are clinically experienced in patient care, hospice services and disease management. Our desire is to provide you with the pharmacy experience you deserve filled with care, service and individual attention.

If you are a current patient, we thank you for trusting us with your care. If you are a potential patient, we encourage you to stop by to meet our team. We would enjoy the opportunity to show you how a locally owned independent pharmacy can better your health.
