Lisa Mendelson is unfailingly pleasant, welcoming, patient and helpful. She has guided my husband through several emergencies and has been a perceptive diagnostician. She has deep knowledge of the many permutations of AL Amyloid and treats each patient with care, allaying fears and calming nervous caregivers. Lisa also has a delightful sense of humor that has helped to brighten some dark moments. Both my husband and I are deeply grateful to Lisa for the excellent care she has provided.
