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 +!

Zulay Loftin

Office Manager

Zulay has been running offices for about 15 years now. She is a local girl, going to College Park High School and then Saint Mary’s College in Moraga where she received her degree in Accounting and shortly after earned her CPA degree. Zulay has always had an interest in how businesses run and how she can help them become even better than they already are. What she has found rewarding in this industry is the amount of people you see on a daily basis and the numerous opportunities she has to get to know them, help them, and have fun with them! 

Being part of this team and partnering with her husband, they have really committed themselves to giving back to their team, patients & community. They are members of the Concord Chamber of Commerce, the Clayton Business and Community Association (CBCA), the Professional Women’s Referral Group and Zulay is also on the Advisory Committee for Mt. Diablo Unified School District. She has come to find that many of their patients are also valued members of these groups! Her favorite part of those groups are the connections she can help create for others to improve their business! So when Zulay is not working, she is with one of those groups or with their son, Jaxon who is 8, in 3rd grade; play dates, volunteering at Eagle Peak Montessori School, and checking out local fun kid things-to-do. She also squeezes in time for cooking for, or traveling and wine tasting with her husband. She even gets him to a LIVE show once in a while!

Janni Lawrence


Jannie has happily been a Hygienist since 1983 and has been working with Dr. Martin since 1984. She went to DVC and is currently part of the American Dental Hygienist Association and the Mt. Diablo Dental Hygiene Association. Jannie has always been interested in health. One of her friends was a dental hygienist and inspired her to follow into this industry. This was a great choice, as she truly enjoys her patients, especially visiting with them and helping them improve their oral health. When she’s not at the practice, she has her grandkids to keep her and her husband busy, along with her loves of photography and dancing. 

Jannie’s Favorite Things: 

My husband and I enjoy finding local places to visit and explore. I am fond of day trips or even weekend trips, not too far away. A great place to take the kids, although adults like it too, is the USS Hornet in Alameda. The Hornet is a national and state history landmark and was part of the Apollo Program. Visitors can see the space capsule in which the astronauts were retrieved from the water and decompression chamber. Fenton’s Ice Cream Parlor, Oakland, is a fun place for lunch or just ice cream. It’s a retro parlor with a large selection of sundaes and cones. We’ve not been but heard the Pinball Museum is also a fun place to visit. – Jannie

I’d like to add another fun family excursion we have taken visitors many times. It is not well known, kind of a San Jose secret! It is the largest Egyptian museum on the west coast. Everyone should visit the Rosecrucian Museum  It is ran by monks. Interesting grounds and museum. Great educational experience for kids. Kelley Park is also a great place to visit while you’re there with the kids. Kelley Park has been recently refurbished with a great lawn, park area and small zoo. Of course, the Tech Museum is well liked also. Our fav place to eat is the Poor House Bistro  It’s an older building fashioned after old places in New Orleans. Great food! – Jannie

Heather Kircher-Martinez


Heather has been with us for a long while; first as a patient and now as our Hygienist. She went to school locally at Diablo Valley College. We get to see her kids just as regularly but now they get their teeth cleaned by her! Michael (9) and Makayla (5) both enjoy that a lot! The part of her job she finds most rewarding is when she’s able to be a part of her patient’s journey from having disease to having a healthy mouth. 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.

Regina McLinn


Regina has been part of our team for a couple years now. She initially helped us as a ‘Temp’ when one of our ladies got ill. Now we get to see her more regularly on Thursdays & Fridays. She went to school at Darton Hygiene School in Georgia and Loma Vista for her RDA license. She has been a hygienist since 2004. She lives locally with her family where she houses a handful of horses, goats, bees and a countless amount of chickens! She has a small farm! When she’s not working, she and her family love to go boating. Regina just had a baby girl – Madeline. Yay! Big sisters Samantha & Lila are a BIG help!

Mariza Patino


Three words that describe Mariza are loyal, playful and generous. Her favorite part of her day at Loftin is working with an awesome crew of not just co-workers, but friends who make coming to work enjoyable  When not at work, Mariza spends her time with her three boys at baseball and football games or places like the beach. The family loves camping, swimming and amusement parks.  She’s also an avid reader, loves to bike and take walks.  She especially loves visiting wineries nearby including Livermore and Napa. 

Wendi Laughlin


She is our newest team member and we’re excited to have her with us. She’s been an RDA for about 20 years now and received her training at Loma Vista. Wendi got introduced to being an RDA back in Idaho where she was covering for an RDA that got ill. From that point on she was hooked! She has greatly enjoyed working with kids, meeting new people and helping everyone have a great smile. Her husband, Chris, and their little men, Silas (1) and Rayce (7) live in Clayton. When the family is together they enjoy camping in Idaho, dirt bike riding and enjoying the local festivities, like the Clayton Art & Wine Festival . When Wendi has a moment to herself she likes to spend it cooking, painting or listening to her music

Jen Crookes


Jen has been a Registered Dental Assistant (RDA) since 1992 and has been with Loftin Dental since early 2013. She graduated from Clayton Valley High School and then went to Bryman College in San Francisco for her RDA training. She recently went to Sacramento City College for her Extended Functions (EF2) training. She has two daughters. Haley is a freshman at Sonoma State and Hannah is at CVCHS. All three of them are big fans of getting their nails done, pedicures and regular massages! Jen knew that she wanted to get into this field when she was getting orthodontic work done on herself when she was 11. She thought the assistant part of the process was interesting and fun. Her first assistant was very sweet and helpful showing her all the steps she was taking and she wanted a similar job. This just in – Jen is newly engaged!  Congratulations, Jen!

Tabitha Hartley


Tabitha has been in the dental industry since 1991 and at Dr. Loftin and Dr. Martin’s office since 2008. She went to Western Career College for training and is currently a member of the American Dental Assistant Association. For Tabitha, it was either dental or cosmetology, but she really couldn’t see herself painting other people’s nails all day! The best parts of her job are the patients and the diversity of what she does day to day. It can be chair side with Dr. Loftin or Dr. Martin, up front or in the lab. When she’s finally home (Tabitha has lived in 3 countries), she enjoys time with her horses and doing some reading. 

Recently Tabitha started REINS (Red’s Equines in Need Sanctuary) located in Hollister, California, to help neglected, abused, abandoned and unwanted horses in need of a safe environment in which to recover and either be placed in a new forever home or a loving sanctuary to live out their days. 

Please see for more information! She also has a Facebook page: search for REINS.
