Meet the Team Behind T&T Smiles
Get to KnowDr. Tia Rinzel
Dr. Tia Rinzel was born in India and raised on a farm in a small town in Wisconsin. As a child, she was self-conscious about her smile until braces gave her new confidence and sparked her love for dentistry. After earning her undergraduate degree at the University of Wisconsin-Milwaukee, she volunteered at a free clinic and shadowed over 150 hours at a local dental office. It wasn’t long before she knew this would be her lifelong calling. As an Indian-American dentist, she understands the importance of blending cultural values with compassionate care.
She attended Marquette University School of Dentistry, where she met her husband and future business partner, Dr. Timothy Semon. After years of practicing within corporate dental settings, Dr. Rinzel knew it was time to build something of her own. She’s passionate about preventative and restorative care, patient education, and helping people feel seen, heard, and confident in the dentist’s chair.
Expertise meets empathy. Dr. Rinzel focuses on high-quality restorative care—from dentures and bridges to advanced implant-supported overdentures. With specialized certifications in minimal sedation, she offers a comfortable, comprehensive experience tailored to every patient’s unique health goals.
Dr. Rinzel holds the following advanced certifications:
In her free time, she loves to play with her dog, Tuxedo, cheer for the Wisconsin Green Bay Packers, and travel. She also loves to be an active member at her church and try new restaurants. If you have any suggestions in Bixby, let her know!
Get to KnowDr. Timothy Semon
Dr. Timothy Semon is a compassionate, highly trained general dentist with a passion for comprehensive care and long-term outcomes. A native of Rochester, NY, Dr. Semon knew he wanted to pursue dentistry at age 16 after undergoing corrective jaw surgery—a transformative experience that sparked his interest in oral health and patient care.
He earned his undergraduate degree from SUNY Buffalo, where he participated in summer research and a prestigious Columbia University dental program. After taking a gap year to work as a dental assistant in an implant-focused practice, Dr. Semon went on to earn his DDS from Marquette University School of Dentistry. It was there he met his wife and future practice partner, Dr. Tia Rinzel.
Dr. Semon is known for his thoughtful, patient-first approach. He is passionate about dental implants, crowns and bridges, partials, dentures, and implant-supported overdentures. His treatment philosophy is simple: “If this were my own family member, what would I recommend?” Every treatment plan is designed with long-term health, function, and patient comfort in mind.
Dr. Semon’s advanced training includes:
- Invisalign® Certification
- Minimal Conscious Sedation Certification (Dr. Jason Goodchild)
- Implant Training at the Colorado Surgical Institute, Oral Reconstructive Success, and the TAG Oral Care Center for Excellence
- International Team for Implantology Curriculum, with ~30 hours of continuing education
- Endodontic Proficiency using WaveOne Endodontic Rotary Systems
Throughout his career, he has successfully delivered numerous crown and bridge cases, and he excels in patient education and treatment presentations. After years of working with DSOs, Dr. Semon and his wife decided to open a private practice in Tulsa—not only to create something meaningful for themselves, but to build a supportive environment for their team and their patients. Dr. Semon is proud to represent African-American dentists in Tulsa and is passionate about ensuring that everyone has access to exceptional care.
Outside of dentistry, Dr. Semon is the proud son of two educators. His father is from the Ivory Coast and his mother is African-American—backgrounds that shaped his strong sense of purpose and connection to his community. He’s also a big LeBron James fan and a believer in doing the right thing—on and off the court.
