Can you work with our existing EHR vendor?

Yes. We have integration patterns for Epic (using App Orchard), Cerner (via the HealtheLife and Code APIs), athenahealth (More Disruption Please marketplace), eClinicalWorks, NextGen, and direct FHIR R4 endpoints on smaller EHR systems. The integration approach depends on the EHR's available APIs, your existing data flow, and the workflows you need to support. Some integrations are real time bidirectional, others are batch nightly syncs depending on the use case. We scope EHR integration carefully during discovery because integration architecture decisions are hard to reverse later.
