Obvious bias, since I work there, but Elation Health is very focused on building EHR software that makes it possible for independent primary care providers to be successful and not have to spend hours per day doing paperwork.

Speaking from personal experience, moonlighting as a paramedic, paperwork is a universal challenge in healthcare (I often spend more time documenting a call than the call itself took from patient contact to transfer of care to the ER). It is shockingly rare for EHRs (regardless of the speciality they focus on) to actively try to make life better for the clinician. That's a large part of why I'm at Elation for my day job; the founders (and therefore the whole company) have a ton of empathy for the doctors (and staff) we serve.

He was part of a hospital system so he used their software. I know nothing about medical software but my impression is that there is a huge amount of paperwork regardless involving insurance, prescriptions, testing, etc. Stuff is more integrated and electronic than it used to be but there's still a lot of manual interactions, phone calls, faxes, etc.
