An Evening With Ryan

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

I have not, but I’m always open to suggestions!

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

Neurologist. This sounded appealing to me until I learned that I would be in school for 10+ years.

3. What about ALL4 has surprised you the most?

I have been pleasantly surprised with how quickly I am getting pulled into projects.

4. What was the most memorable Halloween costume you ever wore?

For a few years in college I went as Michael Meyers from the Halloween series.

5. Stick shift or automatic?

Stick shift. Although I have to say that the next car I get will be automatic. 100,000+ miles on a stick shift is tough on your knee.

6. Who is the most famous person you have ever met?

Billy Gibbons (ZZ Top). I used to see Billy pretty regularly at YardHouse’s CityCentre location in Houston, Texas.


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

People are generally surprised to hear that I’ve been a musician for over 25 years.

8. What would you like to become known for at ALL4?

I’d like to be known as someone that anyone in the company can approach for air quality questions. I’m always happy to have conversations and help out.

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

Air conditioning, a fishing rod, and my brother’s uncanny knowledge of how to clean a fish.

10. What is the one thing that most attracted you to ALL4?

What attracted me the most to ALL4 is their involvement in high level air quality permitting. I also have to mention that ALL4’s reputation in the industry was another factor.
