Dental Hygienist

I was born and raised in Gilbert, Arizona. My husband (also a native) and I have four amazing children. I have four sisters and three of us have worked in dentistry. Plus, I have a son pursuing a career in the dental field and a niece that works in orthodontics. So you could say this industry runs in the family. I attended Brigham Young University and Phoenix College graduating with a degree as a Registered Dental Hygienist. I have over 20 years experience working as a hygienist in Arizona.

Why did you choose dentistry?
I am motivated in my career as a dental hygienist when I see a patient improving their oral and overall health. I love educating about the benefits of optimal oral health. Do you want to make my day? Tell me you started to floss every day (It only takes a minute!).

What is the best part of your job?
The best part of my job is working with fantastic people, both my coworkers and our amazing patients.

What do you do outside of the office?
I love to travel with my family and have new experiences. I enjoy seeing different parts of the world, meeting interesting people, and eating yummy foods. I like to read, hike, and watch movies. I am the current Yahtzee record holder in my family with a score of 522.

Who is your hero? Why?
My hero is Jesus Christ. He is there for the masses and for me personally.

What flavor ice cream would you be?
Vanilla! But never plain. Oh, the possibilities of toppings and mix-ins. It is never the same twice but must include chocolate.

Dental Assistant

Before moving to Arizona, I grew up in Southern California on the beach. I am married with a son and a daughter. I have previously worked in a bank but have wanted to work in dentistry since I was little. I have a real love for dental care and get so excited when I watch someone truly smile!

I was able to train alongside Dr. Walker at Las Vegas Institute and complete all 7 core classes in addition to some advanced dental assisting courses. This has really helped me expand my knowledge and skill set.

What do you do outside of the office?
Outside of the office, I am a spectator for my kid’s sports. I love to hike, watch football, and take a ride on my Harley.

Who is your hero? Why?
My hero is Mrs. Incredible from the movie The Incredibles. She is able to be anywhere and everywhere all at the same time, and does it with grace and a great attitude!

What “lesson from mom” do you still live by?
My mother always told me ‘life isn’t fair.’

What flavor ice cream would you be?
I love all flavors that have to do with birthday cake! It’s always a party!

Lora smiling

Dental Hygienist

Why did you choose dentistry?
Since entering dentistry in May of 1998, I have known that this is the vocation where I belong. The desire to serve others made working in the back office of a progressive dental practice as a Certified Dental Assistant very fulfilling.

To continue the learning process in the dental field I entered into the dental hygiene program at Phoenix College. Upon graduation in 2007 I took the opportunity to travel to Guatemala with the Spirit of Education Foundation where I volunteered as a hygienist in a dental clinic.

This gave me further opportunities to hone my skills and provide treatment for many different types of oral diseases. The time spent serving this population in great need was the opportunity of a lifetime.

What is the best quote you’ve ever heard?
“God is great, beer is good, and people are crazy!”

Our office manager, Tara, smiling as part of our office team

Office Manager

I am a native of Arizona and am married to Dr. Walker. I have two children who keep me on my toes. I have a Bachelor’s degree in Psychology from Texas Christian University in Fort Worth and a Masters in Psychology from the University of Texas at San Antonio. I have been the office manager at this practice since 1999 and enjoy building lasting relationships with our patients. I always strive to provide excellent service and make all our patients feel relaxed.

What do you do outside of the office?
I enjoy reading, exercising, water sports, and spending time with family and friends.

Who is your hero? Why?
Wonder Woman. She is strong, brave, and noble.

What “lesson from mom” do you still live by?
Value time with friends and family. Value good health – one of the most important things in life. Material items can’t buy happiness.

What flavor ice cream would you be?
I would be coffee because I have lots of energy.

Dental Assistant

Hi there! I moved to Arizona over 30 years ago with my husband – WOW! Boy did time fly. I have two WONDERFUL grown sons, a daughter-in-law and one more addition to the family, a happy grandson. Life is beautiful.

I have also been in dentistry for 30 years and still enjoy my job. I graduated dental assisting school in 1983, am CPR certified, and had the privilege of attending the Las Vegas Institute for Advanced Dental Studies for treatment in TMD/TMJ. The majority of my experience lies within the operational side of the office and sitting chairside with Dr. Walker.

Why did you choose dentistry?
Hello? Free dental work… No, let’s get serious; it’s very cool to see patients from all walks of life. I like knowing that I can offer comfort and assurance to someone who is nervous about being in the chair.

What is the best part of your job?
The best part of my job is getting to know so many people and building long-term relationships, earning their trust and knowing that I’m part of a team that is making a positive difference in their lives.

What do you do outside of the office?
I enjoy hiking and exploring nature’s beauty with my husband. I also like spending afternoons with my adorable grandson, family dinners, vacationing, and crossing off my bucket list items.

Who is your hero? Why?
I have to go with Wonder Woman. She is a powerful, strong-willed, compassionate, and independent woman.

Dr. Walker and his staff are excellent! They are welcoming and extremely friendly. Their office is super clean and conveniently located off the 202 and Dobson. Dr. Walker is tops in the field. He's highly qualified and always on the cutting edge of the latest advancements. My family has been Dr. Walker's patients for 20 years now!
