Meet the Doctors

They are one-of-a-kind!

Spencer Mack, DDS Andrew Hansen, DDS

Welcome to Mack and Hansen Orthodontics

Our mission at Mack & Hansen Orthodontics is to be, first and foremost, loving people who are committed to building up every single person we come in contact with. We don’t see ourselves as a business or a company, but as a team of advocates for our patients, their families, and our communities.

While straightening teeth and aligning bites will be our job, inspiring goodwill and elevating others will be our livelihood. We will be the world’s best listeners to those who need our attention and the world’s loudest cheerleaders to those who need our encouragement. We’ll meet selfishness with generosity, coldness with warmth, and we at Mack & Hansen Orthodontics will treat others how THEY want to be treated. Always.

Dr. Spencer Mack and Dr. Andrew Hansen believe that everyone deserves to have straight teeth, a comfortable bite, and a fantastic smile. As such, we make treatment affordable for everyone and are an IN-NETWORK orthodontist with dental insurances.

We are here for you! Whether you are in Longview, just down the road in Kilgore, Marshall, or Gilmer, or in Mount Pleasant, Henderson, or Carthage, we offer LOW down payments, affordable payment plans, and accept ALL insurance, FSAs, HSAs, and CareCredit. Even better, your initial consultation is always FREE!

What patients are saying

“My daughter was very insecure about her teeth. She went from insecure to non-stop smiling in just a few months! For me that was just amazing! We love Mack & Hansen’s welcoming environment and their staff...always smiling, very helpful, energetic, and the most friendly in/out of the office. We Thank You All! I am FOREVER grateful for 'HER' smile!” ~ Sophia H. of Longview
