excellent

Reviewed on Oct 21, 2016

The doctor was unable to answer primary question I had re: clinical study being done on pacemaker. Appeared to know little about it even though it had been included in the medical records I had sent to CC from a different health organization. Lack of awareness made it impossible to explore possible side affects and second opinion re: effectiveness and recommendations.

Dr Callahan is very attentive.
