Our story
A practice at the same address for twenty-eight years.
Two specialist orthodontists, one Fleming Island office, and twenty-eight years of Clay County families. Thousands of the smiles walking around this county started in our chairs.
Oasis Orthodontics, in short
Oasis Orthodontics is a two-doctor specialist orthodontic practice in Fleming Island, Florida, founded in 1997 and known as Aiosa & Hoffman Orthodontics until May 2026. Dr. Derek Hoffman and Dr. Samantha Montoya see new patients; founder Dr. Lori Aiosa is semi-retired and continues with the families she has known longest.
Rooted in community.
A straight smile is the part you can see. What we are actually watching is how a child grows into their bite, and whether they will still like their smile at forty.
We have been serving the Fleming Island community for twenty-eight years, creating personalized smiles that last a lifetime. What started as Aiosa & Hoffman Orthodontics has grown into one of Clay County’s most respected practices, now continuing as Oasis Orthodontics under the leadership of Dr. Derek Hoffman and Dr. Samantha Montoya.
Over the years we have had the privilege of transforming countless smiles, from children taking their first steps toward a confident grin, to adults rediscovering the joy of a beautiful smile. We are honored to be part of so many families.
“Specialist orthodontic care rooted in genuine relationships, delivered to three generations of the same Clay County families.”- continuing the standard set by Dr. Lori Aiosa in 1997
The practice changed names in 2026, but the address and the standard of care have not. Dr. Lori Aiosa, who opened these doors as Aiosa & Hoffman Orthodontics in 1997, is now semi-retired and continues to see her existing patients here.

Orthodontic specialist.
Both of our doctors completed an additional three-year, full-time, university residency in orthodontics and dentofacial orthopedics in addition to dental school. That difference matters.
In Florida, any licensed dentist can offer braces or aligners. A specialist orthodontist has completed a full-time residency accredited by the American Dental Association in moving teeth and guiding jaw growth. Dr. Hoffman trained at the University of Florida; Dr. Montoya trained at UF as well, and is board-certified by the American Board of Orthodontics.
For routine teen cases, results from either path can be similar. For complex bite work, surgical planning, severe crowding, growth-modification cases in children, and adult treatment after years of wear, residency-trained specialists tend to plan and execute these cases more predictably. The difference is most visible in the cases that do not go to plan, which is the moment the depth of training shows.

The people behind your smile.
The same people greet you at the first visit and at the last retainer check. They will know your name, and before long they will know which of your kids hates the fluoride tray.
Modern tools. Quiet ones.
We buy equipment when it changes what we can do for a patient, and we leave it alone when it only changes how the practice sounds.
- Precise planningDigital impressions and 3D imaging for accurate treatment plans and custom appliances.
- Comfortable treatmentGentle techniques and innovative appliances that reduce discomfort and treatment time.
- Progress monitoringAdvanced monitoring options so we track your progress efficiently at every stage.
Treatments for all ages.
We offer six treatments, and part of the consultation is telling you which one actually fits. Retainers come after all of them.
We don’t want to be your orthodontist for now. We want to be the practice your kids remember when their kids need braces.
