Accountability
When one doctor owns your care from start to finish, there is no question about who stands behind the result.
Prosthodontic, implant, and everyday dental care — planned and delivered by Dr. Luciano Retana.
Arapahoe Dental is a single-doctor practice in Boulder, Colorado. Luciano Retana, DDS, plans and completes every case himself — from routine cleanings to implants — so your care stays consistent from start to finish.


We measure success in years, not appointments. Every plan is built around your long-term health — fewer redos, better-fitting restorations, and outcomes designed to hold up over time.
We take the time each case needs. Careful planning and lab-level detail come before speed.
The same hands plan, prepare, and deliver your treatment — nothing is lost in a handoff.
