Common complaints

Limited/very small volume of reviews on some platforms (e.g., only 1 review on WebMD practice listing), making overall complaints/experiences hard to assess
One WebMD practice listing indicates 'front desk will cancel less than 4 hours before appointment' (suggesting scheduling/office policy issues rather than clinical complaints)
