Quest Dive - Diane Thiele

Hi, I'm Diane and I could go on about my qualifications but I think it is more important that you know that I have been in the travel business for over 30 years and I love what I do. I love to travel; I love to scuba dive and I love adventure. I'll treat your vacation as if it were my own.

I’m just a girl from the midwest, as a child you’d find me eagerly packing my bag a week before departure, on the way to visit family. Today, little has changed, and I’m still staring out of airplane windows. Once on land, there isn’t much time until I explore underwater and delight in it’s silence. Travel, for me, is an assault on the senses- sights, experiences, flavors and sounds every where you look. I want to help you experience this amazing world.

Quest Dive - Diane Thiele

Woof! I'm Penny a.k.a. office dog. I, too, chase squirrels, chipmunks and occasionally deer! When I'm not outside doing those fun things, I'm here in the office napping, begging attention or barking at anything that passes by (you might hear me in the background, if you are on the phone with my human). I'm not so fond of water but I sure do like to watch the fish in our aquarium. I hope to howl with you soon.
