I am curious where is this data sourced from! Thank you for putting this together

It's been a painstaking process of combing consolidator websites (eg. PetVet Care Centers, NVA) for practice names, verifying and adding them to a list over the course of over a year. I now get many people writing in to report practices that aren't on the list - admittedly it's not complete list as practices are still being acquired (although independents are now in the minority) and often the old practice branding is kept and the fact it's PE owned is hidden.
