Meet Our Staff

Dave Mahon, DDS
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 allow 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 3 wonderfully unique and dynamic children. I have 2 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, 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. Loved seeing Monet’s Garden in Giverny. And 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.

 

 

Shari, Office Manager

I was born in St. Louis Missouri and moved to Las Vegas in 1979 where I met and married my husband of 27 years and raised three amazing children. I am now the proud “Mimi” to four grandchildren. I love spending time with my family, especially my grandkids. I joined Siena Dental in 2013, bringing over 15 years of practice management experience.

When I’m not at work or spending time with my family, I enjoy traveling, reading, cooking and going to the movies. I am a huge sports fan and you can always find me cheering on the St. Louis Cardinals and Green Bay Packers. I am so excited Las Vegas will finally have professional hockey and football franchises.

In June 2016, I took my dream vacation to Ireland. It was as beautiful as I had always imagined. I was able to visit several cities on a 10 day trip by train. The food was amazing as well as the locals: they really know how to enjoy life.  The highlight was staying in Dromoland Castle and being able to try my hand at falconry, “the sport of the kings”.

The most beautiful place I visited was Killarney National Park, we enjoyed a horse and buggy ride through the Gap of Dunloe and drove around the Ring of Kerry; breathtaking scenery!

 

 

Shannon, Dental Assistant

Originally from California, I moved to Las Vegas at the age of 7. I have been a dental assistant for over 10 years and I really enjoy working with patients. I joined Siena Dental in 2014, and love being part of an amazing team.

Away from the office, I'm usually spending time with my family and taking my daughter to all of her extracurricular activities. I'm also a student at the College of Southern Nevada pursuing a career in dental hygiene.

Krisdie, Registered Dental Hygienist

I am from a small town in Utah and graduated magna cum laude from Dixie State University, where I received my Bachelors of Dental Hygiene. My desire to help others inspires my passion for dental hygiene. Because dental appointments are often dreaded, I strive to make patients feel comfortable and cared for.

Away from the office, I enjoy traveling, spending time with my family and exploring the outdoors. One of my favorite hobbies is fishing; I’m always excited to hear a good fish story!
