Meet the Staff


Patient Coordinator/ RDA

Tammy - Patient Coordinator

Tammy – Patient Coordinator

Lifetime Smiles has been my home since 1994.  I started out as a registered dental assistant but now I am happy to greet you as your treatment coordinator.  My dental experience started when I was in high school.  My mom was an assistant and office manager for years; and this is how I came to love dentistry.  I cannot imagine working with anyone else but Dr McDonald, as she’s compassionate, caring and a great dentist.

I live in beautiful Valley Center with my dog Clyde and my 3 chickens.  I have 2 children and they are both away at school.  My son JD is in Arizona going to motorcycle mechanic school.  My daughter Brooke is in Iowa attending cosmetology school, so I sort of have the empty nest syndrome going on… I guess I should enjoy it while I can, because they both say they are coming back after they finish.  I enjoy being outdoors, either boating on the river or riding my quad at the desert.  My next adventure is going to be getting my motorcycle license and buy a Harley. We will see.

Jayme – Hygiene Coordinator

Hi, my name is Jayme and I have been around dentistry my whole life but I have been working as a registered dental assistant since 2000. I started my journey with Lifetime Smiles in April of 2003. This is such an awesome place to work, our patients are the best!

I have a wonderful husband and 2 daughters. Morgann is 15 years old and loves track and field. Our newest baby girl (Payton Skye) is 4 years old and such a joy to be around. After 5 years, we finally finished building our house in Ramona. In my off time, I find myself at track meets and volleyball games.  I enjoy ridding my horse Pedro with my kids and going to the desert and boating.

Brooke – Treatment Coordinator/RDA

Hi my name is Brooke and I started as a dental assistant when I was 15 years old! I have now been in dentistry over half my life. I grew up in the dental field and I love working with people and helping them achieve their ultimate smile and dental health. Therefore it only makes sense to work with lifetime smiles where caring for people is our main priority.

On a personal note I have been married over 15 years to my best friend & love of my life “Taylor”. We have been enjoying living in San Diego now for over 11 years. I love to dance, throw parties & I enjoy being with friends! We have no kids yet but we have a precious little Maltese, “Sophie” who keeps us very busy & entertained!

Cynthia – Registered Dental Assistant

I have been in dentistry since 1995 and a Registered Dental Assistant for 15 of those years.  I am proud and honored to be on the team at Lifetime Smiles where we practice compassionate, caring and beautiful dentistry.

My husband Dave and I live in Valley Center with our 4 kids and really enjoy the quiet and quaint little town feeling.  When we are not working or looking after our kids we enjoy going to the desert and to the river.  I also enjoy baking and crafts with my daughter Julie, and watching my son play water polo and surf.  We all enjoy fishing together as a family and I have even been known to catch a few fish of my own!

I look forward to taking care of your smile at our office in Escondido.



Sterilization Tech

Tony - Steralization Tech

Tony – Sterilization Tech

My name is Tony and I am the new kid on the block compared to my team members. I am the sterilization technician at our office and I tend to jump in and help out with just about anything I am asked of.   I really have finally found my niche!  My co-workers are amazing and I look forward to many years at Lifetime Smiles.

Blessed to say, I married my high school sweetheart and we have a beautiful 3 year old daughter Melanie or as we like to call her “MelMel.”  We enjoy spending time together keeping Mel-Mel active with playing soccer, swimming lessons and anything she enjoys dong.  When I’m not with my girls I enjoy spending time at the gym or on a hike, “my alone time” I like to call it!

Register Dental Hygienist

Lindsey - Registered Dental Hygenist

Lindsay – Registered Dental Hygienist

My name is Lindsay and I’m privileged to serve you with a smile!

My roots come from Washington State where I often visit my family and vacation on San Juan Island. A lifelong saying passed on to me- “family is everything”- is my inspiration for compassionate and personalized service to my family at lifetime smiles.

My interest for dental hygiene was cultivated by my education at Loma Linda University School of Dentistry, where I earned by bachelors degree in 2010. Thereafter, my career flourished in downtown Los Angeles, where I thrived in a multicultural, metropolis of experience and opportunity. In continuing my professional skills, I earned my periodontal soft tissue laser certification through the World Clinical Laser Institute.

When I’m out of the office, I’m a devoted wife to my husband, ken, and adopted mother to our treasured daughter, Athena. My personal interests include early morning devotions, nature walks, hiking, beach combing, cooking escapades, and book-hunting with a cup of chai or espresso in my hand.

Maureen - Registered Dental Hygenist

Maureen – Registered Dental Hygienist

Hi, my name is Maureen. I have enjoyed working in the dental field for many years, first as a dental assistant and now for several years as a hygienist.

I grew up in Vista and went to school in Los Angeles to complete my dental hygiene education. My husband and I are long time residents of Escondido and are proud parents of our daughter who recently received a master’s degree in architecture.

As a Southern California native, I can’t imagine living too far from the beaches, mountains and desert. In my spare time I like playing tennis, hiking and reading. Lifetime Smiles is an office that I am happy to be a part of, as the focus is on quality, patient care, and the latest in dental technology and advancements is our number one priority.



Registered Dental Hygienist


Grant – Registered Dental Hygienist

Hello, my name is Grant Gill and I love being a Registered Dental Hygienist. I grew up in a family of dental professionals, so being a hygienist was a natural path for me. My hometown is Palm Desert and I currently live in San Marcos with my wife Leah. I have lived in San Diego for over 3 years and I love it.
I am so proud of being a part of Lifetime Smiles. I can honestly say that I couldn’t have asked to be on a better team of dental professionals. Our practice is solely patient focused, there is always laughter and fun, and most importantly the best today’s technology has to offer.
I look forward to meeting you and providing you with a great hygiene visit!
