Merging Dups but keeping certain data

I'm trying to figure out how to merge duplicate rows but I only want certain data. How do I do that?

Example:

Here are two rows, the second row only has email and phone number. I want all the data from row 1 but only the email and phone# from row 2. 

Is this possible to merge them and keep all data from row 1 and now add the email and phone onto it? I have a list of 15,000 I need to go through and trying to find a faster way than manually coping and pasting the email and phone on to the row with the most data.
