Our Experience

Sari Schiff - Principal

Sari Schiff

OPS evolved from a transition that occurred in my own career path. I had spent 20 years in retailing at every level of service. Working in Store Operations to Real Estate Prospecting, Human Resources, Marketing and Special Projects. With my retail experience and seeing a trend declining in retail, I discovered medical management and took my skill set to retail medicine. Working with independent medical practices on sustainability and growth strategies. 

In my time working on those practices I was able to identify and implement best operations to help grow those businesses. We always start with patient experience and developing human resources. I truly love what we do and who we work with. Empathy is a driver to success.
