From the measurement desk
Written for the question you actually typed.
Each piece answers one owner question in the owner's words, with the measured data we have and arithmetic anyone can check.
Is it weird to contact patients who haven't been in for two years?
The awkwardness is yours, not theirs — measured. What long-lapsed patients actually experience when a practice reaches out, and the wording that lands.
Should we spend on new-patient ads or on recall first?
The order-of-operations answer, with arithmetic: why the quiet file usually out-earns the ad budget, and the one case where ads should still win.
