We transitioned to Principle Health for our Lab Provider, in my 30 + years I have never had such a smooth transition converting to a new lab, very impressed with the professionalism and communication! Thank you Team Principle!

Partnering with Principle Health Systems has been a game changer. Providing phlebotomy and PCR testing makes them a one stop shop for meeting patient needs. There are so many things that set this company apart. Communication, customer service, attention to detail and attitude of excellence, just to name a few. Highly recommend partnering with Prinicple Health Systems.

Started a relationship with Principle last year with Touchstone Communities in our Houston area Communities. That was the start. This was followed with our new company, ML Healthcare. We wanted to continue this partnership with Principle in our new facility, Cypress Pointe Health and Wellness. Working with Principle has been great! They are true Partners in our healthcare facilities. Our organization values our relationship with Principle, and we look forward to continuing this relationship in our new facility – Sylvan Shores Health and Wellness.

Our Skilled Nursing Facility has used Principle Health Systems for the past three years. I have never reached out to them for assistance that I wasn’t able to connect with someone right away. They have skilled professional staff that provide excellent customer service and communication.
