 Hello! My name is Marissa Sanchez. I was born and raised in Lake Havasu City, where the sparkling waters and stunning landscape shaped my love for my hometown. One of my greatest passions is the incredible opportunity to participate in our patient's transformative journeys. I find immense joy in helping people discover newfound confidence and comfort in themselves. Full Arch Dental Implant Center holds a special place in my heart, as it allows me to meet extraordinary individuals everyday and contribute to making their lives better.





 Hello! My name is Rhiannon Glidewell. I was born and raised in the charming heartland of Missouri, but recently made the move to stunning Lake Havasu City. Here, I have found my true home at Full Arch Dental Implant Center, where I have forged wonderful camaraderie with an exceptional team. As lead dental assistant, I get the pleasure of being a part of these life-changing procedures. Working in the dental field fills me with so much joy, as there's nothing quite like the happiness of helping patients achieve dazzling new smiles and newfound confidence.




 Hello! My name is Gracie Hernandez. I grew up in a quaint small town in California, but in 2018, I found my new home in the vibrant Lake Havasu City. The joy of helping people smile and boosting their confidence is what draws me to this work. I'm captivated by the constantly evolving technology that we get to use everyday. The team here at Full Arch Dental Implant Center is a close-knit group, creating an amazing and supportive environment. We love serving our community through our passion - implants!




Hey there! I'm Hailey Valentine, a sunny California native turned Lake Havasu Local, riding the wave of my educational journey. When I'm not hitting the books, I'm hitting the lake - big time into water sports and any excuse to dive into some splashy fun. Off the water, I'm an adventure junkie with a suitcase always packed. Exploring exotic places and diving deep into new cultures is my jam. But wait - there's more! My ultimate high? Crafting stunning new grins.


   As the Patient Relations Manager for our all-star All-on-Four Dental Implant Team, I bring the same passion and energy to ensuring every patient's journey is smooth and their smiles transformational. Whether you're here for a quick fix or a full smile makeover, I'm your go-to gal, making sure your experience is nothing short of epic. From your first consultation to your last follow-up, I'm here to guide you, cheer you on, and celebrate every step of your smile revival. Let's make dental magic happen together!



 Hey there! I'm Kendra, hailing from the sunny vibes of Rancho Cucamonga, California. Fast forward through the sit com of my life, and you'll find me now soaking up the sun and fun in Lake Havasu City for the past seven years. When I'm not hanging out by the lake, I'm out and about with my four-legged buddy, conquering parks and winning the "best day ever" awards. 


   Ever since I could spell 'stethoscope', I've dreamed of the medical world. Turns out, it's as awesome as I had hoped. I spend my days turning frowns into Hollywood-worthy smiles and giving folks a new reason to show off their pearly whites. It's not just a job-it's a way of adding a little sparkle to the world, one grin at a time!




Hi! I'm Makena. I moved to Lake Havasu from California (like a lot of people have). I am going into my second year of college and I couldn't be more excited for what life will throw at me next! I grew up coming to Lake Havasu and Parker my whole life, so of course boating is very big in my life. I recently moved out on my own and started this amazing job as a sterile tech and couldn't be happier! I am so lucky to have joined a team as great as this one. I am in charge of setting up all rooms for appointments and for big surgeries! I love heading into a room and always having the best conversations with our amazing patients. The journey I get to go on with these patients is truly amazing. Being able to see patients walk out of our building with their brand new smile makes me fall in love with my job every time!
