He paid for his own schooling with scholarships and working as a real estate broker, during which time he was awarded Realtor Magazine’s ‘30 Under 30’.

After graduation, Tarik partnered with his father at TLW Construction and is now serving his 14th year as vice president and also helps to manage a sister steel company - Caliber Metal Buildings. During this time, Tarik has shared responsibility for the design and construction of roughly 4 million square feet of self-storage and through this experience has developed a reputation as one who understands his trade and takes special interest in the operability and functionality of the finished product. Tarik has developed three storage projects on his own account resulting in valuable knowledge gained from the owner’s perspective which he is able to implement in his construction client’s projects.
