RE: Recommendation for [first & last name]
I've worked on the same team with [first & name] for [#] years at [company name]. I found [him/her] to be an exceptionally talented and driven team member.
[Mr./Mrs./Ms./Dr.] [last name] is deeply motivated and never had any problems getting things done right the first time. Everyone in the office seemed to really like [first name] and I had the best time working with [him/her] .
I would strongly recommend [first name] to any organization. [He/She] is an honest worker and would be a great asset to anyone's team.
