Patient Comments (2)
Woodside, NY |
Don't expect any sympathy from Doctor Diefenbach. She's unemotional and rather unfriendly. Also, don't expect her to return your calls or emails, or to bother explaining to you what your test results mean (she is way too busy). After that first visit, expect to deal exclusively with her assistants.
in New Jersey |
An amazing Dr. who is one of the best in her field. Subject matter expert in Lymphoma, highly personable/family-oriented yet professional at every level. Responsive, timely, caring, interactive... all the things you would hope for in world-class patient care. Her team is also second to none.
