Meet Our Team

Libby

Registered Dental Hygienist

I am a graduate of the College of Southern Nevada’s first dental hygiene class more than 30 years ago. I’ve worked in many dental offices in the Las Vegas area. I have been with Siena Dental since 2002. I am here to provide comprehensive dental hygiene services to our patients. We are here to serve you, our patients. The continuing education courses I attend allow me to provide the most current and effective periodontal therapy, as well as educate my patients about the latest hygiene products and theories essential to their oral and overall health.

Certification in both laser periodontal therapy and local anesthesia allows me to provide a comfortable dental experience for our patients.

I’ve been married to the same great man for over 38 years and have three wonderfully unique and dynamic children. I have two grandkids that I brag about all the time. It's what grandparents do! Aside from work, I enjoy traveling abroad. My husband and I have visited Rome, Berlin, Prague, Vienna, southern Germany, and Switzerland, and we finally got to explore Paris and northern France.

We paid our respects at the D-Day Beaches as well as the American Cemetery. I loved seeing Monet’s Garden in Giverny, and I even took a cooking class in Paris! I look forward to seeing you at Siena Dental and ensuring you have a pleasant experience here.

Brea

Registered Dental Hygienist

I am a Las Vegas native and have enjoyed watching our valley grow over the years. I worked in a dental practice for six years, performing both administrative and chairside duties, before attending dental hygiene school at the College of Southern Nevada. I graduated with honors in 2012. One of my proudest achievements is receiving the Marsha Ayres France Outstanding Student Award. I’ve always enjoyed dentistry, but most of all, I love helping people by expanding my knowledge as our profession continues to advance.

Recently, I obtained my laser certification in dental hygiene therapy. I take pride in providing great, individualized care for my patients, and I am ecstatic to be a part of the Siena Dental team.

Away from the office, I enjoy spending time with my husband and two young children: our toddler and newborn keep life very fun and entertaining! Exercising, boating on the Colorado River, and cooking are just a few of my hobbies.  I look forward to introducing myself to our patients and hope I can make a difference in ones' oral health.

Susie

Office Manager

Hi, my name is Susie, and I’ve been proud to be part of the dental field for over 30 years. I began my career as a Registered Dental Assistant in California and have spent the last 25 years here in the Las Vegas Valley working as a Treatment Coordinator and Office Manager.

I’m a first-generation Hungarian-American; my parents immigrated to the U.S. in 1958. I’ve been fortunate to grow up immersed in Hungarian culture and can speak, read, write, and of course, eat Hungarian very well!

Before dentistry, I had planned to become a music teacher and learned to play seven instruments. These days, I still enjoy playing classic rock on the drums now and then with my husband’s local band here in Henderson, Nevada.

Outside of work, I love boating, traveling, entertaining, and spending quality time with friends and family. I also enjoy long walks with my little American Eskimo dog, Luna.

I truly love being part of the team at Siena Dental and look forward to meeting all of you!

Krisdie

Registered Dental Hygienist

I graduated magna cum laude from Utah Tech University in 2015 with a Bachelor of Science in Dental Hygiene. Growing up in a small town in Utah, I developed a deep appreciation for genuine connections and making others feel at ease. That foundation continues to guide my approach to dental care today.

I'm passionate about helping patients achieve and maintain their oral health in a setting where they feel comfortable, supported, and truly cared for. One of the most rewarding parts of my profession is building lasting relationships and helping people feel confident in their smiles.

When I’m not in the office, you can find me enjoying the outdoors, spending time with family, filling in as a ranch hand, or cheering on my favorite teams at sporting events. Go Aces!

Kiana

Dental Assistant

I was born and raised in Maui, and moved to Las Vegas in 2014. I pursued a career in dentistry because I enjoy meeting people and interacting with patients. I joined Siena Dental in early 2018 and love working with such an incredible staff.

I’m always excited to hear a good story and look forward to meeting all of our patients. I hope to make your visit comfortable and enjoyable. Outside of work, I love going to musical festivals, hanging out with family and friends and going to the gym.

Lourdes

Dental Assistant

I am originally from California and have been a dental assistant since 1998. My husband and I moved to Las Vegas in 2015. We have two adult children; our daughter Wendy resides in Las Vegas and our son Jason in California. We enjoy taking our granddaughters to the Lake, swimming and riding bikes.

I’m also a fan of the Los Angeles Dodgers and Denver Broncos. It’s a pleasure working with Dr. Mahon and the Siena Dental team and getting to meet new people.

Sunshine

Dental Hygienist

Hi, my name is Sunshine! I’m originally from the Las Vegas Valley and have also lived in both California and New York. I earned my Bachelor of Science in Dental Hygiene from Loma Linda University School of Dentistry, and for over six years now, dental hygiene has been a meaningful and fulfilling part of my life.

I’m proud to be part of the Siena Dental team, where I work with a team that genuinely takes pride in what they do. We work together to create a positive, patient-centered experience every day, and I truly enjoy being in an environment that encourages trust, teamwork, and growth.

One of the most rewarding parts of my job is building confidence and lasting relationships with my patients. I love getting to know people from all walks of life and learning from them every day. My goal is always to make patients feel at ease in my chair, and I find great joy in helping them gain a better understanding of their oral health. Educating and empowering patients to achieve a healthy, confident smile is what drives me.

Outside of work, I cherish spending time with my amazing husband and our three children. We enjoy cooking, hosting, being active, and spending quality time in our home and with God. We also love exploring Lake Mead and all the natural beauty Nevada has to offer.

I feel incredibly blessed to have a career that allows me to connect with people, educate, and make a lasting impact on their health and confidence.
