Hi wasky and welcome. Will try to help give you the "guided tour" of treatment options for Metro Boston.
You have already learned about MGH/MEEI. I have, first hand, met soooo many that had their AN treatments with Barker/McKenna. If you go to the forum home page, do a "Search" option for Barker, McKenna, Mass General, MEEI, etc... you will see MANY conversations that will end up in your search results. Folks here have been great about reporting outcomes, potential after affects, etc, so the forums are a VERY valuable resource for the historical info regarding their work. Too many that participate on the forums for me to count, but some that come to mind are
CrazyKat, jcinma, kbonner, etc, just to name a few. I have met them many many times over the years and can't even tell they had brain surgery!
Brigham/Womans..... Dr. Peter Black's team is top notch. He has been doing a great deal of international traveling recently and Dr. Elizabeth Claus and the rest of the team are assisting with his procedures. Now, what I can share is this.... Dr. Claus was (and is) my first NS on my AN journey. Honest, down to earth, hand-picked protege of Dr. Black. FYI.... she is now (officially) a member of the ANA USA Medical Advisory Board (noted on the ANA home page) and I'm thrilled to see her join the ANA team. I've known her for 5 years... and would recommend her in a New York minute.
gingerbread6 (on this forum) just had her surgery with Dr. Black.. and is doing follow up with Dr. Claus. I believe she is in agreement with me about this overall statement.... a terrific resource as well.
Tufts University. I know of
Helga (here on the forums) that had her recent surgery there. I know of someone else that recently had their surgery there as well (he is not active on the forums but have spoken to him/his wife on the phone as I'm a member of the ANA Willing-to-Talk list). Both folks are reporting good outcomes but some after affects that are not uncommon to the surgical procedure.
Since surgery is the route to be done (ie: AN too large for radio-treatments), I know of many that had radio treatments in Boston (such as myself) and know that the neurosurgeons affiliated with the radio-teams are top notch as well.
We are blessed to live in a medical mecca here in Metro Boston.... so, many, such as myself, do not see the need to travel elsewhere (and to endure the expenditures, esp. in today's tough economic climate). Bay State Med and UMass Medical are also both top notch.... for me, I'm kinda partial to the facilities in downtown Boston.
So, I hope this helps. My suggestion would be doing the "search" option here to get a feel for what everyone is reporting. I have met (face to face) far too many that have been treated locally.... and most of them are here on the forums and more than happy to share their experiences with you.
Hang in there... and again, welcome!
