  • Challenges with communication, including unresponsive phone lines, lack of follow-up, and difficulty reaching staff via patient portals
  • Frustrations with medication refills and prescription management
  • Issues with being dismissed or released as a patient without clear communication

"Worst office I have ever dealt with... The office staff was unhelpful, difficult and ineffective. ... 2 days before my next appt I found out, with no email, letter or phone call that they had “released” me as a patient."

Healthgrades (Dr. Edward Condon)

"The lady at front desk is so rude. She lacks empathy and because of her I decided to switch doctors. Plus getting an appointment takes months and when you finally do get an appointment it takes forever to be seen."

Vitals (Dr. Andrew H. Lane)

"Dr. Eschler was the only endocrinologist that took my concerns seriously about my goiter. She was very thorough."
