About Us

Our offices.

The office was established in Denver, Colorado in 1972 by Dr. Robert G. Schallhorn and relocated to Aurora, Colorado in 1981. Dr. Schallhorn is a world-renowned periodontist whose vision in saving teeth helped establish groundbreaking work in periodontal regeneration. His landmark studies with hip marrow bone grafts in the 1960’s changed the way periodontics is practiced today. We are happy to continue that vision of improving the health and ultimately the quality of life for our patients.

Meet Our Team

We consistently receive positive feedback from patients who truly enjoy and appreciate our team members. We take pride in having long-term relationships with our patients. Many of have been coming to see our doctors since 1972 for their periodontal/implant needs.

Our dental hygienists are extremely well educated and experienced in the field of periodontics. They are key providers of active and preventive periodontal therapy. Our hygienists attend continuing education programs numerous times per year and stay abreast of the latest techniques and technologies to help our patients achieve and maintain good oral health. Dental hygienists are your key to successful long-term care. They are excellent communicators and go the extra mile to ensure a successful program, which is the heart of prevention.

We are fortunate to have exceptional dental assistants with years of chairside experience. They not only assure that our time together in treatment goes smoothly, but are involved as oral hygiene educators, providing pre- and post-surgical care and for much of the behind the scenes support, such as sterilization, cleanliness, and infection control.

You will find the front desk staff extremely professional and capable. Their experience assures that your visits are pleasant and enjoyable.

We feel it is critical to grow and learn and as a result continuing education is a key part of our office. In addition we have annual training for OSHA where infection control systems are reviewed for added safety and comfort. Our entire staff is certified in CPR annually.
