Get to know Lindsey

Have you ever had a nickname (or two)?  If so, what are/were they?

In high school I was called “Dimples” and even received a pair of “dimple pokers” for my birthday one year, more commonly known as chopsticks.

When you were 8 years old, what did you want to be when you grew up?

My best guess is probably a musician – at that time I played the hammered dulcimer and later played the flute throughout high school and college.

What is one of the most memorable experiences you have had at ALL4?

Every ALL4 holiday party has proven to be memorable and is something I look forward to every year!!

What was the most memorable Halloween costume you ever wore?

I dressed up as my then-boyfriend’s hamster in college, Toby, complete with hula hoops wrapped in tin foil at my sides as the wheel. Needless to say, it was a little challenging to navigate the Halloween party that year…but that boyfriend is now my husband, so I guess it was worth it!

Stick shift or automatic?

Easy – stick shift.

Who is the most famous person you have ever met?

I didn’t meet him, but I saw Sean Connery’s locker at Skibo Castle in Scotland…

Do you have any hidden talents that people you meet would not expect?

I learned recently that I can make a mean deviled egg – which is strange because I usually avoid the kitchen.

What are you known for at ALL4?

My loud and intimidating personality? No, probably not…

If you were stranded on an island, what are three things you couldn’t live without?

Coffee, chocolate, and pasta.

What is the most unique thing about working at ALL4?

The culture and the people that make it up. Everyone here works hard towards a common goal and can spend quality time together both in and out of the office.
