@vgdmayo Thanks to @loribmt for tagging me in this conversation. OHSU, going to their website, gave me this information for drs there treating the condition your husband has: https://www.ohsu.edu/health/find-a-doctor/search?accepting=&age_group=&distance=&gender=&insurance=&language=&location=&online=&pcp=&shuffle_seed=PS-66089c29a76a25.04961389&sort=&term=waldenstroms%20macroglobulinemia&vector_name=&vector_value=

I am a patient at Willamette Valley Cancer Institute and Research Center, in Eugene. They have several locations. I plugged in your husband's condition and here is the result of the doctors who treat it, and the locations they are at: https://www.oregoncancer.com/physicians?specialty=&special_interest=Lymphoma&location=

I am biased, and admit that. I have been a patient for 5 years, and feel grateful to have Dr. Yasenchak as my oncologist. By the way, he was a Mayo Clinic resident doctor before he moved out here 8 years ago, and still keeps in touch with his colleagues.

If I can be of any further help, please let me know! As a fellow blood cancer patient, we know the frustration of getting a great medical team in our corner.
