As far as estate planning specialists are concerned, consider reaching out to Denise McCarthy at Cody, Cody and McCarthy. They have an office in Newton (that's almost Metrowest, right?)

Also, I see that
@eboos has an office in Worcester. I haven't had the occasion to work with him yet, but he seems like he might be a good choice as well.
I handle basic estate planning (simple wills, POAs, conventional revocable trusts, etc.), but for complicated engagements and HNW individuals, I generally refer out.
