My boss asked for a referral for an interior designer to decorate our new office building so I reached out to the Yelp community and got turned on to Neilsen. I sent all the contact info on to my boss and she was thrilled that I had a referral for her so quickly! Brownie points for me!
Nosomuch. While Nielsen might be extremely talented, his follow through and time management were less than adequate. He wouldn't return my boss' phone calls without her leaving him several messages, was 2 weeks late turning in his proposal, and would go out of town for weeks at a time without letting her know he was gone....I could go on and on, but really, I don't want to re-live the embarrassment again.
I know there is the chance that perhaps there were some crossed circuits here, especially since there are so many positive reviews, but honestly, something was amiss with this experience and that's why the low marks (I don't give a lot of low marks normally and it pains me to do so).
I'm not saying don't use this company, because they are probably extremely talented, but I would evaluate the situation you're in before you recommend them to someone so you don't end up in the same predicament I am in.
