Negar Massah, DDS
Dr. Negar Massah is a compassionate prosthodontist who finds true joy in helping her patients feel confident through healthy, beautiful smiles. She earned both her Bachelor of Science in Biology and her Doctor of Dental Surgery (DDS) degree from Virginia Commonwealth University. Inspired by a deep love for esthetics and the life-changing impact of a confident smile, she pursued specialty training in Prosthodontics at the University of Alabama at Birmingham.
Kind-hearted and detail-oriented, Dr. Massah is known for her gentle yet comprehensive approach to care, blending clinical precision with genuine compassion. She believes in restoring not just function, but also self-esteem and confidence through personalized, esthetically-driven treatment. She is a proud member of the American Dental Association (ADA) and the American College of Prosthodontics (ACP).
She grew up in Toronto, Canada and moved to the United States in 2005. While attending dental school, she met her husband, and together they now have a daughter and a son. Their move from Virginia to Colorado was inspired by their love for the outdoors and a desire to raise their children in a vibrant, active, and diverse environment.
When she’s not caring for patients, Dr. Massah loves spontaneous adventures with her family—exploring the world and making lasting memories along the way.

Mark Ehrhardt, DDS – Retired
Thank you for 37 years!
Upon starting this practice 37 years ago, my hope was always to create a place that truly served the Brighton community and their dental needs where patients felt listened to, respected and part of a dental community built on trust and care for years to come. That commitment remains at the heart of this practice. As I step into retirement, I am confident our team is more committed than ever to making your experience in our office even better. I am proud of the direction Brighton Restorative Dentistry is heading and excited for what is ahead.

John Gittins DDS, FACP
Dr. John Gittins earned his bachelor’s degree Weber State University then graduated Magna Cum Laude in 2011 from Marquette University School of Dentistry in Milwaukee, Wisconsin. He was one of four dentists accepted into the Army’s prosthodontics residency training program at Fort Gordon in Augusta, Georgia, and after his residency, in 2015, served as the Chief of Prosthodontics and Dental Technology at Fort Riley, Kansas, where he was instrumental in the care of soldiers and the mentorship of over 30 general dentists. After his military commitment, he began teaching prosthodontics at the Roseman University College of Dental Medicine while also maintaining a private practice.
Dr. Gittins was inducted as a Diplomat by the American Board of Prosthodontics following the completion of his board exams in 2015. This is the highest honor a specialist can be awarded. He is one of only 1,000 worldwide.
Dr. Gittins and his wife, Jessica, have four beautiful children: Harper, Holland, Haisley and Hatcher. He loves having fun with his family, exploring nature and eating good food.

Erich Lutz, DDS
Originally from the small town of Tazewell in southwest Virginia, Dr. Erich Lutz developed a passion for dentistry early on. He was inspired by his father and grandfather—both dentists who served their local community. He earned his Bachelor of Science in Biological Sciences from East Tennessee State University and went on to complete his Doctor of Dental Surgery (DDS) degree at Virginia Commonwealth University, where he met his wife. After his dental training at VCU, Dr. Lutz had the opportunity to lead his family’s dental practice after his father’s retirement for seven years. In his role, he gained valuable experience managing both the clinical and administrative sides of dentistry, continuing a legacy of patient-centered care built over generations.
After seven years of working alongside his father, brother and sister, Dr. Lutz made the move to Virginia Beach with his wife. Now a father of two, Dr. Lutz and his family decided to make Colorado their home, drawn by the state’s natural beauty, vibrant communities, diversity and active lifestyle. He brings with him a broad skill set and a steady hand in all aspects of general dentistry—from restorative procedures and extractions to root canals and preventive care. Known for his precision, calm demeanor and commitment to clinical excellence, he looks forward to building strong relationships with patients and becoming a trusted part of the local dental community.
