Star Ranch Dental

Peter R. Barnett, DMD and Courtney L. Geiger, DDS

Voted Best Cosmetic Dentist in Frisco/Plano 2015 and 2016 by Living Magazine readers and Best TMJ Dentist 2016 in their area, Drs. Barnett and Geiger offer experienced, quality dentistry with a wonderful support staff. One of the most successful and fastest growing dental practices in the Dallas/Fort Worth area, Star Ranch Dental invests in state-of-the art dental technology to provide patients with compassionate, comprehensive care. Their expanded services include general and restorative dentistry (cleanings, tooth-colored fillings, and porcelain crowns), and a wide array of cosmetic services including veneers, adult orthodontics, and whitening. A specialized focus is offered on head, neck, and temporomandibular joint (TMJ) pain, as well as periodontal therapy, dental implants, and airway management for sleep apnea treatment.

Compassionate, Personalized Care

Star Ranch Dental continues to be a dentist-owned practice focused on the patient instead of production. Their philosophy of care is defined by putting people first, continually defining excellence, and the belief that a happy smile equals a happy life. A healthy smile creates confidence and opportunity, and the staff at Star Ranch Dental is committed to reaching each patient’s needs and desires. Patients are made to feel appreciated and valued by being recognized and greeted by name by a smiling receptionist. The elegant waiting room sets the tone for a relaxing visit.

“Our staff truly cares about each and every person that walks through our door,” Dr. Barnett said. “They have a heart to help with genuine care.” Many loyal patients have been with Star Ranch Dental for years. They enjoy the leading-edge dental care experience that Drs. Barnett and Geiger offer in a comfortable, patient-centered environment. Their philosophy of care includes creating a “map” to optimal dental health and explains the oral systemic link—how everything that is happening in the mouth plays into the patient’s overall health.

Focused on reducing stress, the dental facility has been designed for patient relaxation. Luxuries including warm/cool neck wraps, cool gel eye masks, and warm blankets make patients feel right at home. In addition, the continually updated technology offers patients the best dental experience possible for brilliant smiles and improved oral healthcare.

Meet Dr. Barnett

Dentistry was a natural choice for Dr. Peter Barnett. He is the grandson of two dentists, and his grandmother founded the New York City Community College Department of Dental Hygiene. Founder of Star Ranch Dental, Dr. Barnett graduated from the University of Pennsylvania Dental School of Medicine and continues to be passionate about staying up to date on advancing dentistry in the general, restorative, and specialty areas. His Texas Headache Relief program offers patients reprieve from years of head, neck and jaw pain. Dr. Barnett’s years of experience, coupled with his straight-forward yet calming approach, helps patients truly understand their dental needs. He has cared for multiple generations in many of his patients’ families. He enjoys working with them to create a customized dental treatment plan unique to only them.

Meet Dr. Geiger

Dentistry provided the perfect balance between Dr. Courtney Geiger’s love of art and her love of science. Since joining Star Ranch Dental, loyal patients drive long distances to continue having their dental needs met by her. Her meticulous attention to detail has earned her the American Academy of Cosmetic Dentistry Award, the Southwest Academy of Restorative Dentistry Award, and the Eleanor Bushee Senior Woman Dental Student award while at Baylor College of Dentistry. Her patients admire her expertise and gentle nature. “I try to use my artistic eye to visualize the outcome of each procedure before I begin, whether it be a root canal or a cosmetic procedure,” Dr. Geiger said. Together, she and Dr. Barnett consult on cases to offer a comprehensive list of services in an effort to treat patients without referring them to a specialist outside their office. “Our services are leading-edge and high-tech, but our approach is very personable,” Dr. Barnett said.

“We never want our patients to dread their visit by being anxious or fearful,” said Dr. Barnett. “We strive to offer a stress-free, spa-like atmosphere that encourages patients to relax.” He added, “Our pleasing approach is tailored for each patient’s unique needs. We have a fantastic staff that helps facilitate patients’ treatment plans and alleviates any fear or anxiety they might have.”
