About the clinic
The schedule is the philosophy.
Most clinics book four patients an hour and call the squeeze inevitable. Wrenmoor books two, publishes its prices, and holds sick slots open on purpose. Everything else follows from that arithmetic.
How we work
Thirty-minute visits
Double the industry norm, by design. Diagnosis is mostly listening, and listening doesn't compress well.
Prices on the wall
The self-pay menu is printed, posted, and honored. Insurance is verified before the visit so the bill never surprises anyone.
One doctor, your family
The same physician sees your kid's strep and your father's blood pressure. Patterns live between visits — continuity is how they get caught.
Dr. Tobias Quennell, MD
A doctor who did the math and changed the schedule.
Dr. Quennell spent a decade in a high-volume group practice watching fifteen-minute slots turn medicine into triage. Wrenmoor is the clinic he rebuilt from the schedule up: fewer patients per hour, prices anyone can read, sick slots held for the day they're needed, and lab results that come with an explanation instead of a shrug. Board-certified in family medicine; practicing in Grapevine since 2016.
