MEET THE DOCS
Dr. Whitney Weiner DDS, MS
American Board of Periodontology, Board Certified in Periodontics & Dental Implants
Dr. Weiner’s love of helping patients started at a young age. Her mother is a highly respected double PhD psychologist and professor, and her father built a medical insurance business from scratch. He also reached the base camp of Mt. Everest as he battled multiple sclerosis. These strong role models showed her the importance of family and perseverance, and she uses these lessons daily to improve the lives of others.
She was awarded a full academic scholarship to Colorado College and graduated with honors. Receiving several awards for excellence in research, practice management, oral pathology, and leadership, she was the sole recipient of a scholarship for outstanding achievement in periodontics at Iowa. She had what she describes as “the typical doctor/dentist dilemma” and thought she wanted to be a plastic surgeon.
She worked in the ER the summer between her freshman and sophomore years of college. While she loved the thrill and adrenaline of it, she missed developing relationships with patients. Her grandfather, a dentist, and a role model to Dr. Weiner, suggested she shadow some oral surgeons and periodontists. After her experience, she took a leap of faith and decided to pursue dentistry. Her aptitude and love for surgery made her an excellent periodontist, and her passion for building strong relationships with her patients found a perfect home in the dental field.
Dr. Whitney Weiner treats each patient like family, and she would never dream of a one-size-fits-all approach. With an emphasis on education, open communication, and personalized care, Dr. Weiner empowers her patients to make the right decision for themselves. She believes in being a true specialist and ensuring her patients are always treated by the best of the best.
In 2016, Dr. Weiner was chosen as one of the “Top 25 Women in Dentistry” by Dental Product Report and named the “Most Interesting Person in Dentistry” for February by Curasan.com. In 2017, Incisal Edge named her in their top “40 under 40” young, rising dentists in the country. Always at the forefront of dental technology, she attends multiple regional and national professional meetings each year.
She loves to educate her fellow dentists and has lectured both nationally and internationally on the oral-systemic link (the connection between oral health and overall health), periodontology and implantology, and the importance of being a specialist.
Dr. Weiner was specially selected for membership to DENTSPLY Implants’ PEERS North America, an exclusive group of under 100 key opinion leaders and experts in the field of implant dentistry. She was voted a “Top Dentist” by a group of her peers in Hour Magazine every year since moving to the metro Detroit area. Sharing her insight in the world of implant dentistry, she attends and speaks at regional and national professional meetings. Most importantly, her patients love her and the exceptional results she delivers.
When she isn’t working, she loves spending time with her husband, Eliot, their three young boys, Jake, Max, and Wes, and their rescue Pitbull mix, Mollymook. She loves travel, adventure, and isn’t afraid of danger. With an unforgettable gap year spent in Central America living on $10 a day, a fulfilling winter as a ski instructor, and two years living in Australia with her husband, her passion for life radiates through everything she puts her mind to.
