How do I remove comma at the end of a string when using <apex:repeat> in Visualforce email template? (parsing)

I have a Visualforce email template based on Opportunity. In it I want to incorporate all the Opportunity Team Members whose Member Role = XYZ, say, "Sales Engineer". The following code works splendidly... 
<b>Sales Engineers:</b>
     <apex:repeat value="{!relatedTo.OpportunityTeamMembers}" var="oppTeam">
          <apex:outputText rendered="{!oppTeam.TeamMemberRole ='Sales Engineer'}">
          {!oppTeam.Name}, 
          </apex:outputText>
     </apex:repeat>
Except that it (obviously) appends comma + space to each repeat, leaving a trailing ", " at the end:
 
Sales Engineers: Maggie Simpson, Krusty the Clown, 

Where I want:
 
Sales Engineers: Maggie Simpson, Krusty the Clown
 
(i.e. with no ", " at the end). There's probably more than one way to do this, but I've reached the end of my coding knowledge at this point. Ideas?

Hi Beto, you could do this as it is not standard in visualforce this functionality: https://developer.salesforce.com/forums/?id=9060G0000005WMUQA2
There is an idea raised to incorporate a separator in visualforce: https://success.salesforce.com/ideaView?id=08730000000YIuvAAG
If it helps please like and mark as correct, it may help others.
