Array Formula to Pull in All Values Related to Certain Employee

[mrmmickle1]

I have data that looks like this:

Excel 2012
	D	E	F	G	H	I	J	K	L
5	Finalize performance of TWIST, VIM, NID, OTX1, ONECUT2;								Allan
6	Assess IP landscape that would allow for methylation to be run on LC480s under MethyLight patent license (call Mike Rondelli)								Jeff
7	Assess sequence for possible primer/probe sites that would allow for CpG-agnostic amplification/hybridization								Allan
8
9					1
10	develop strategy to assess CDKN2A INDELs by 2-3 <200bp multiplexed primer sets								Andrew
11	demonstrate multiplexing with PIK3CA of either single 324 primer set or combination of <200 primer sets multiplexed								Andrew
12
13			1		1		2
14									Olivia
15
16			1		1		2
17	SubTask								Olivia
Master List

Is there a way for me to use a formula to pull in all values associated with a specific name...

For Example:

Excel 2012
	L	M	N	O
5	Allan	Jeff	Andrew	Olivia
6	Finalize performance of TWIST, VIM, NID, OTX1, ONECUT2;	Assess IP landscape that would allow for methylation to be run on LC480s under MethyLight patent license (call Mike Rondelli)	develop strategy to assess CDKN2A INDELs by 2-3 <200bp multiplexed primer sets	SubTask
7	Assess sequence for possible primer/probe sites that would allow for CpG-agnostic amplification/hybridization		demonstrate multiplexing with PIK3CA of either single 324 primer set or combination of <200 primer sets multiplexed
