Tony Alonso


Dr. Alonso completed his undergraduate degree at Oklahoma State University and completed a Master’s degree from the University of Tulsa prior to obtaining a Doctor of Pharmacy degree from the University of Oklahoma. After completing internships at Oklahoma State University Medical Center, USA Drug, and the University of Oklahoma Schusterman Center, Dr. Alonso worked as a Pharmacy Manager for Drug Warehouse and Walgreens in Tulsa and Sapulpa. He joined One Stop Rx as a way to better serve patients through the science and art of compounding.

“Working with physicians to individualize prescription medications is extremely rewarding professionally. Helping patients become healthier and happier through compounding is extremely rewarding personally as well”.

As a Tulsa native, he has continued to raise his 3 children in Tulsa along with his wife Cindy. He enjoys volunteering as a youth basketball and baseball coach in the community. Cindy has been the owner and director of Happy Campers Academy on Cherry Street since 2003. “There isn’t another place on the planet I would rather raise a family than Tulsa. I love this city and I am proud to work at an independently owned pharmacy that puts the needs of Tulsans first”.

Specialized training includes the PCCA Compounding Boot Camp and the PCCA Comprehensive Compounding Course in Houston, TX.


Melinda Mast


Prior to completing her Doctor of Pharmacy degree from the University of Oklahoma, Dr. Mast worked as a pharmacy technician and intern for Drug Mart located in Tulsa. She completed internships with Cushing Regional Medical Center, Oklahoma State University Medical Center, and USA Drug. Dr. Mast has worked as a pharmacist for May’s/Med-X, Drug Warehouse, and Walgreens. She joined One Stop Rx as the Pharmacy Manager to ensure the philosophy that the patient always comes first.

“I knew I wanted to make a difference in patients’ lives and customer service is a top priority at One Stop Rx. Sharing my knowledge with my patients and counseling them on commercially available medications and individualized compounds is the reason I became a pharmacist in the first place”.

Melinda was born and raised in Sapulpa. Following in her footsteps, her son and daughter both have careers in the pharmacy profession. She enjoys volunteering with the American Cancer Society’s Relay for Life and the Walk to End Alzheimer’s. “It’s flattering that my kids think so much of me and my profession that they have decided to work in the same field”.

Jocelyn Anstine


Jocelyn Anstine began her career serving the public at the age of 16​, when ​she gained an appreciation for serving the members of her community. Upon graduation from the University of Oklahoma , she worked as an in house claim representative and as an underwriter for State Farm Insurance. Missing the face to face interactions she had formerly experienced, she decided to attend pharmacy school in hopes of returning to the community. Since completing her PharmD also at OU, she has worked in a retail/compounding pharmacy. Although she briefly worked for one of the ​large​​ retail chain pharmacies, she feels much more at home in the community​ pharmacy​ setting at One Stop Rx in​ ​Tulsa​, OK​.

Jocelyn and her husband Travis live in a suburb of Tulsa with their 4 children aged 17 to 2, and their dog Max. In her spare time, she enjoys running, going to the lake with her family, watching her kids play volleyball, baseball, and cheer and fall Saturdays watching Sooner football.
