What Matters
John says Coffee matters a lot: "I like how it tastes" and he's "gotten into the science of making espresso," calling it "science making coffee in that way."
John says Telemedicine matters "increasingly so," as it helps "improve access" and allows doctors "to see them where they are."
John says Pizza matters, noting "you should be able to try different kinds of pizza and have your favorite. That's important."

Takes (8)
Kids with complex medical needs shouldn't have to travel six hours just to have a conversation with a specialist.
Seeing a teenager with autism comfortable on his own couch makes the whole visit work better — for him and for me.
You can still form a real doctor-patient relationship through a screen — that used to feel impossible to me.
Constipation affects up to one in four pediatrician visits, but parents still feel like they can't talk about it openly.
If kids had asthma, parents would swap strategies freely — GI problems deserve that same openness.
After all my training, I still rushed my constipated toddler to the ER thinking it was appendicitis — it fools everyone.
Telehealth isn't right for everyone every time, but it genuinely improves access for families who need it most.
Making espresso is basically applied science — pressure, volume, speed — and I'm a little deep into it.
