About Tulsa Oklahoma Team

Drue and Lisa Smallwood

Drue and Lisa are the thankful owners of Mighty Dog Roofing of Tulsa. They’ve been married 20 years and have lived in the Tulsa area throughout that time. They have four boys and enjoy chasing them all over Green Country watching more football, basketball, baseball, and soccer games than they ever thought they’d see.


Drue has 20+ years of experience in the construction industry. During this time, he has engineered complex systems, managed projects, led teams, and delivered millions of dollars of products and services.  He loves to work with a team to accomplish a shared goal, and he enjoys sitting down with a client or colleague to discuss an issue and develop an action plan towards a solution. He strives to work together with everyone to make an impact in the world, whether in our workplaces, communities, or families.  Drue has volunteered for 15 years with a non-profit called Bless the Children Ministries (btcm.org). He’s been to Uganda five times helping orphans, their guardians, and the community where they live to achieve sustainable success.  In addition to Uganda, he has visited nearly 30 countries in his career and on missions trips, but he still loves to be on “Tulsa Time” more than anywhere else.   He enjoys coaching youth soccer, serving in his local church, visiting great Tulsa eateries, live music, traveling, and working around his property with his dogs, Ace & Gracie. 


The Tulsa Mighty Dog Roofing team has over 50 years of construction and roofing experience. The team has lived and worked in the Tulsa community for decades, and they will be here when the storms come and go. They look forward to working with you to beautify and protect your home and business.

Meet the Team

Dennis Cagwin
General Manager
As a roofing and construction industry veteran and longtime Tulsa resident, Dennis is excited to help our customers with their home exterior needs. Dennis is married and has two boys, two girls, and a dog named Lucky--his family keeps him busy! He is actively involved in the community where he can be found running the game clock or working behind the scenes at a local church or school event. Dennis is the kind of guy you can trust, and he will be leading the Mighty Dog team in Tulsa.

Tim Schnakenberg
Operations Manager
Tim comes to Mighty Dog with years of roofing experience. He is a loving husband and father of twins and a dog named Sadie. Tim is a walking sports encyclopedia and enjoys being a fan of his two kids’ whatever season they are playing. He and his family are active members of their church where they can be found serving wherever needs arise. One thing many do not know about Tim is he had a previous career as a radio announcer. We are fortunate to have Tim leading our Mighty Dog project team in Tulsa.

Chief Dog
Ace is a full-blood Australian Shepherd that is about as loyal as the come. Often found at his owner's feet or riding around in the family vehicle, Ace represents our core values, trust and dependability.

The Protector
Gracie is the protector of the Smallwood property. Part Pyrenees and part mystery, she has been known to hold her own while surrounded by a whole pack of coyotes. She is all bark and no bite, though (don’t tell the coyotes).

The Lucky One
Rescued as a puppy, Lucky has been a favorite of the Cagwin kids for many years now. Dennis kind of likes him, too.
