Dr. Pettyjohn’s Treatment Philosophy


At Pettyjohn Family Dentistry, we are committed to honesty and integrity as well as excellence in the dental care that we provide. Dr. Pettyjohn was raised on a farm in Iowa and at her core holds the ideals of honesty, trust, and hard work. You can be assured as our patient that we will always strive to provide you with the highest level of care and compassion. We are an office who truly wants to get to know you and always keeps your best interests at heart.

Dr. Pettyjohn comes from a dental family as her father and god-father are both dentists. From a young age, she has developed a strong sense of caring for others and upholding the ideals of our dental profession. Dr. Pettyjohn is highly respected among her colleagues and has reputation built on honesty, integrity, and a deep sense of professionalism. She respects the sacred call of healthcare, cares deeply for her patients, and is highly trained and skilled to provide them with the best dental care possible. In a world that is more and more focused on a corporate, production driven model of healthcare, Dr. Pettyjohn is a breath of fresh air.

At Pettyjohn Family Dentistry, we take a calm, gentle approach to your family’s dental care. We believe in spending as much time as possible with each patient in order to listen to your needs and develop a personalized plan for you. We are committed to informing patients of their options and then allowing patients to choose the treatment that is most appropriate for them. We are NOT an office who prescribes “cookie cutter”, “quick fix”, or “one size fits all” treatment. We believe in providing only that care we would want for ourselves and our family members.

We also believe in having a caring and consistent staff so that you can look forward to a friendly face at each visit. We do NOT believe in utilizing expanded function dental auxiliaries. This means that our hygienist, Libbye, will take care of all of your cleaning and deep cleaning needs and that Dr. Pettyjohn will take care of the rest. This is NOT an office where you will find a dental assistant placing your fillings or adjusting your crowns. We believe in the doctor providing treatment that only the doctor was trained to do.

We also believe in using the highest quality dental materials and laboratories for results that will last. You can rest assured that we stay up to date on the best dental materials and techniques; however we are NOT an office to incorporate new technology without a proven track record. Sometimes the latest and greatest is not the best. We also believe in utilizing local dental laboratories for optimal communication, assuring our patients with the most functional and esthetic restorations possible. We also think it is important to foster relationships and support other small businesses in our community.

Last, but not least, Dr. Pettyjohn is also committed to being a lifelong learner. It is amazing how quickly dental techniques and technology can change. Dr. Pettyjohn commits many hours each year to continuing education and improving our patient care and overall dental practice. She is currently a member of the Colorado Chapter of the International Team for Implantology, a study club of some of the most talented and respected surgeons and restorative dentists in the state. Dr. Pettyjohn focuses most of her continuing education hours on fixed restorations, implants, and occlusion.
