Love and Learning

Dr. Taher Dhoon was born in Utah, where he learned to love the outdoors. He later moved to California, receiving his BA in Physiology and Neuroscience from the University of California, San Diego. He went on to earn his Doctor of Dental Medicine degree from the University of Pennsylvania School of Dental Medicine. While in dental school, random seating placed him next to another aspiring dentist named Bridget, who would later become his wife.

Training and Missions

Dr. Dhoon has traveled all over the country to learn and perfect the most complex techniques available in modern day dentistry. He has also traveled to the Dominican Republic two separate times to perform implant surgeries and complex bone grafting procedures for the locals in those less fortunate communities.

Master of Dental Implants

He has seen first-hand the power of dental implants to change lives. That’s why he developed a proven system that delivers the best a quickest implant solutions available. He has become a go-to resource for dental implants with his implant expertise sought after by other dentists looking to implement the same process and achieve the same level of implant success.

Setting Patients at Ease

Dr. Dhoon has also completed training and become licensed to provide oral sedation for his patients. This has helped him improve the dental health of his patients who were once too anxious or fearful to visit the dentist. Appointments with sedation are easy and stress-free as patients are finally able to relax and receive the dental treatment that they have put off for so many years.

Home Life

He married his dental school sweetheart (Bridget) and they have three energetic kids named Connor, Claire and Jonathan. He has big plans for his son as he eventually plans to buy an old 60s-70s Chevy to rebuild with his son and then hand the keys over to him for his sixteenth birthday (as long as self-driving cars haven’t made this project obsolete.) His little girl Claire has him wrapped around her little finger. Adding to the family is a golden retriever named West and a little rescue poodle-shih tzu named Jordy. As a family they enjoy exploring all the hidden secrets Colorado has to offer, staying active, gardening, and spending time with friends.
