Mallory was extremely well-prepared for my appointment. She had been through all of my medical records and even pulled my CPAP records. I have never had a provider pull the CPAP records. She is very knowledgeable in the pulmonology area.

Mallory Hatmaker is the gold standard of how healthcare professionals should treat patients. The time she takes to ask questions, review treatments, explain what's going on. She provide rare quality of care in these times of insurance mandated medical visits.
