SQL Server 2012 - DB Table Record Merge help needed

Question

Ok, so here is what I have and what I am trying to do.  I have a couple of tables I need to pull information out of.  The information is stored singly per record in each table like this:
User 1 Info
User 1 Info1
User 1 Info2
User  1
Info3
User 2 Info
User 2 Info1
etc...
What i want to do is query these tables and get my results back like this:
User 1 Info, Info1, Info2, Info3
User 2 Info, Info1
Is this even possible?  I ask because I need to tie these tables to another table to get some results I need to review but the table in its current state creates multiple records because of their design.
Thanks.

Answer 1

Ok, so after looking online for examples and looking at the answers here and my original note, I notice I didn't really explain this very well or correct.  So I want to re-explain this.
I have two tables I need to combine into one result list so I am creating a view for this.  
Table 1 has Name that I need
Table 2 has ContactKey that I need
The two tables are tied together by a common factor of Group Key.  The SQL code I have to combine the tables into one view looks like this:
SELECT        dbo.GroupMain.Name, dbo.GroupMember.MemberContactKey
FROM            dbo.GroupMain INNER JOIN
                         dbo.GroupMember ON dbo.GroupMain.GroupKey = dbo.GroupMember.GroupKey
This results in a list of Names (which are group names that any specific record can be tied to and any record can be tied to more than one) and a MemberContactKey number which is a unique identifier for the record tied to this Name.  So if I organize the
results, I will get something like this:
Name MemberContactKey
Group1 123456
Group2 123456
Group3 123456
Group1 456789
Group2 456789
Group1 789456
Group2 789456
Group3 789456
And so on.  The Name option can be expanded to any number of groups I need/want to create with no problems.  How I want this to look is like this:
MemberContactKey Name
123456 Group1, Group2, Group3
456789 Group1, Group2
789456 Group1, Group2, Group3
I tried using a STUFF call but that didn't seem to want to work unless I did it wrong.  
Thanks for the assistance
