“I have worked with IPS for 20 years in multiple different medical offices. Customer service with Leila Montgomery is amazing. I can call, text or e-mail and someone will get back with me right away. Couldn’t ask for better service or nicer people. They always get the report to me quickly so the provider and patient don’t have to wait.  Overall I love IPS. They go above and beyond to give great patient care and their pathologists are knowledgeable and some of the best around.”
