About Our Saginaw Dental Office When Dr. Rupeshwar Renkuntla first moved to Texas, he knew he wanted to provide the community with a standard of dentistry that was truly second-to-none. As an experienced dentist who’s worked in multiple dental offices as well as the Army National Guard, he’s excited to provide the community of Saginaw dentistry that is truly state-of-the-art, whether it’s through his high attention to detail or the technology he incorporates to improve the dental experience.
