Pozitivf Fertility San Antonio

Where it all started

Pozitivf Fertility was founded in San Antonio in June of 2022 by industry pioneer Dr. Francisco Arredondo with one mission: to provide access to high quality, affordable fertility care to as many people as possible.

Dr. Arredondo reimagined the traditional fertility care journey by applying a cross discipline approach. Borrowing principles and methodologies like LEAN management and Toyota Production System, Dr. Arredondo eliminated redundant tests and procedures that didn’t add value. The result was a streamlined process where patients could get the same result (a baby in your arms), with fewer visits to the clinic, in less time and at a fraction of the cost.

See for yourself

Probably the best way to understand the Pozitivf difference is to take a tour of our offices. For visitors who have been to traditional fertility clinics, they see right away–because they see everything! The more you know (and see), the more comfortable and confident you’ll be embarking on this exciting journey.
