What's the Difference Between An RDA and An RDAEF?

An RDA is a Registered Dental Assistant and an RDAEF is a Registered Dental Assistant Extended Functions.  The RDAEF goes through an additional year of school and must pass a State Board exam with their dentist to be accredited this title.  They work closer with Dr. Loftin. Think of them like a physician’s assistant. It’s a unique position and they work very hard for this certification. We are lucky to have two RDAEFs at Loftin Dental, Jennifer and Tabitha.  

What Does This Mean for You and Other Patients?

RDAEFs allow us to be more agile in our practice and to attend to more patients in need of complex procedures.  This includes fillings, adjusting dentures and other services. Each RDAEF works closely with Dr. Loftin and are fully capable for these and other advanced treatments. 

Dr. Todd A. Loftin

Dr. Loftin attended the University of California at Berkeley for his undergraduate education and then attended the University Of California School Of Dentistry at San Francisco (UCSF). At UCSF, Dr. Loftin expanded his education by becoming laser certified and practicing minimally invasive dentistry which is a highly used conservative approach to keeping patients mouths healthy. Post-graduation he continued to add to his education and received certifications in Cosmetic Dentistry, Invisalign, implant placement and restoration, and oral conscious sedation. During the last 15 years, he has had a multitude of successful cases, from simple restorations to cosmetic veneers all the way to full mouth rehabilitations. He is well versed in general dentistry, cosmetic procedures and more complex mouth reconstruction. He has been an active member of the California Dental Association, the American Dental Association, the International Congress of Oral Implantologists and the Academy of General Dentistry.

When he is not practicing dentistry, he enjoys golf and playing on a local softball team and bowling team. Dr. Loftin and his wife, Zulay, are also on the ‘Great Balls of Fire’ Bocce Team headed up by Wendy Moore and play in downtown Clayton, California, during the summer session. He also enjoys spending some quiet time with Zulay in Napa, Sonoma or Carmel for some wine tasting. He also has a bit of the travel bug and hopes to visit new places every year with his family.

Being an avid golfer these days, he and his son, Jaxon, are able to practice hitting balls and playing a couple holes here and there at different golf courses. A favorite course is near his father’s place in Pioneer, where they can head out towards the end of the day and try out a few holes …without bothering other golfers! Jaxon, 8 years old now, has been really enjoying the one-on-one time with his ‘Papa’, especially now that school has started at EaglePeak Montessori!

In the last couple years he has become a member of the Concord Clayton Sunrise Rotary and has really come to enjoy the part of his life where he is able to give back to the community he loves.

Dr. Loftin is a gentle and caring Doctor that will work with you to ensure you are receiving the treatment that best suits your needs. He feels privileged to care for children, adults and those with special needs.

Our History

Established in 2012.

We were honored to work with Dr. Albert Martin, Jr., DDS as he transitioned into retirement. As of August 2014, he did happily retire. Thankfully he and his wife, Renee, still come to visit us for their regular dental checkups and catch up lunches. They have been enjoying time with their family, especially their newest member – a granddaughter! Traveling is another norm for them as well. Fun times! He had been at this location on Washington serving our Concord community for over 30 years. We held a small retirement dinner for him and our team where we presented him with a signed framed picture – his first team and his most recent. We had the picture up in our practice for a while gathering as many signatures as we could! We also ‘retired’ one of his jackets and placed his last name and the year he retired on the back of it.

The start of the transition began in 2010.  It started with monthly lunches where they would talk and get to know each other as people and as clinicians. Because it was important to both of them to have a smooth transition, Dr. Loftin began working one day per week and worked side by side with Dr. Martin spending quality time getting to know his future patients and team. This went on for 2 years. Then yay – the time came and we became the new Dr. serving our Concord community.

Dr. Loftin has over 10 years of experience working in multiple locations and found this location perfect to serve. He & his wife are very excited to work with everyone and continue the great service Dr. Martin has provided. So even though we are “newer”, we have a long history in this community that we look forward to continuing & growing even better. We’re looking forward to the next 30 years +!

The benefits are endless and she likes knowing she had a part in that process. Her goal to give you the best experience possible and keep you healthy! When she’s not with us, she likes going on weekend trips with her kids or just hanging out at home. She plays the piano too and has recently began to teach her daughter how to play.
