World-Class Expertise. Hometown Care.
Choosing orthodontic care is about more than finding someone who can straighten teeth. It’s about trusting someone with your smile, your health, and, for many parents, your child’s care.
At Mountain View Orthodontics, families don’t have to choose between exceptional expertise and personal attention. Dr. Sebastian combines the latest advances in orthodontics with care that’s thoughtfully personalized to your health, your goals, and your smile.
World-Class Expertise, Right Here at Home
Dr. Sebastian has spent his career advancing the science of orthodontics through research, teaching, and clinical practice.
With more than 20 years of experience, he is a Clinical Associate Professor at Case Western Reserve University, has published more than 25 peer-reviewed articles, co-edited two orthodontic textbooks, and has taught orthodontists on six of seven continents.
But what matters most is how that expertise benefits the patients he sees every day in Longmont and Berthoud.
Every patient receives a thorough evaluation and a treatment plan designed specifically for them. Dr. Sebastian considers not only how your smile will look, but also your bite, jaw function, airway, long-term oral health, and overall well-being.
Care That’s Personal to You
No two patients are the same, and neither are their treatment plans.
Whether you’re considering early treatment for your child, braces or Invisalign® for your teen, or orthodontic treatment for yourself, Dr. Sebastian takes the time to understand your needs and explain your options. Sometimes the right recommendation is to begin treatment. Sometimes it’s to wait.
The goal is always the same: to recommend the care we would want for our own families and create a healthy, beautiful smile designed to last.
Hometown Care Means Being There for You
Mountain View Orthodontics is locally owned and operated by people who live, work, and raise their families in the same communities as their patients.
That local connection shapes the experience. The team gets to know patients, celebrates their milestones, answers their questions, and does everything possible to be there when they need them—including when unexpected orthodontic needs arise.
It’s advanced orthodontic care delivered with kindness, consistency, and the personal connection of a hometown practice.
The Best of Both Worlds
Families throughout Longmont, Berthoud, and the Front Range choose Mountain View Orthodontics because they can find something special close to home: a doctor helping advance the field of orthodontics and a local team deeply invested in the people they serve.
World-Class Expertise. Hometown Care.
And a treatment plan built around you.
