dr-richeySam Richey, DDS

Dr. Samuel Richey is caring and thoughtful in his efforts to help his patients receive quality dental care. As a dentist he enjoys helping them improve the health and appearance of their smile through the use of cosmetic, orthodontic, or implant treatment. He and his wife, Heather, are happily married and have eight beautiful children. They reside in the Riverton-Herriman area.

Sam grew up on a family farm in eastern Idaho, where he dreamed of being an adventurer while he herded sheep, chased a bear, raised buffalo, and dug “spuds.” He graduated as a mechanical engineer and worked in robotics at INEL and later as a fuel engineer at Geneva Steel. He was fortunate after dental school to be trained for two years at an advanced cosmetic and family dental office in Albany, Oregon. He then started a family practice in Boise with an emphasis in cosmetics, orthodontics, and implants. After leaving Idaho, he started practicing here in Utah in 2005. He has received a fellowship in implants from the Misch Institute. Sam has a heart of service and adventure, as he and Heather traveled to the Andes Mountains to a Peruvian Orphanage, “The Sunflower,” to provide dental treatment and teach hygiene and dental care. Sam enjoys hiking, running, sports, beekeeping, and continuing his dental education.

Alisa Davenport, RDH – Dental Hygienist

Alisa joined our office in June 2013. She works alongside Lori as a part-time hygienist and normally sees patients on Tuesdays. Alisa was born in Northern Idaho and grew up mostly in the Idaho-Washington area, although her elementary school years were spent in Las Vegas, Nevada. In high school, she worked in a dental office and has wanted to become a dental hygienist ever since. She attended BYU-I for a couple of years, receiving her associates degree, before transferring to Idaho State University. There, she received her bachelor’s degree in dental hygiene. While attending ISU, Alisa met her husband and they were married two weeks before she started her final year of dental hygiene school. After graduating, Alisa and Jason moved to the Salt Lake valley for Jason’s job. Alisa worked full time as a hygienist for two years before having her first son. She then stopped working so she could be a full-time mommy while occasionally working as a temp hygienist. Now that she has her job as a mom down, she is very excited to be working one day a week as our hygienist. She loves the dental field and getting to know patients and helping them achieve optimal oral health and a beautiful smile.

Alisa enjoys reading, taking walks, baking, decorating her house, spending time with family, and running after her two sons. She also loves to travel and hopes to one day be able to do more of it!



Lori Sterrett, RDH – Dental Hygienist

Lori began working for us in February 2011. She is working alongside Alisa as a part-time hygienist and normally sees patients on Mondays, Wednesdays, Thursdays, and occasionally Fridays. Lori was born and raised in Salt Lake, and, after graduating high school, she attended BYU-Idaho and took a year studying interior design. She was then married and had 4 children, who are all now adults. Two are graduates from college, three
are married, and two have now given her 3 grandchildren! Being a full-time stay-at-home mom has been her greatest joy, but as her children began to grow older, she felt it was time to be a part of something more. After weighing her options, and having always been very fascinated with the dental industry, she went back to school and has loved the journey; she is looking forward to what’s ahead. Lori loves working with people and making them feel comfortable and “at home,” even if it’s in the dental chair.

Lori was recently remarried to a great man named Steve, and they currently live in the Ogden area. She has always been interested in community service and would like to extend her training to helping others, locally and in other countries. In 2015, she and Dr. Samuel Richey traveled to Ecuador to provide humanitarian dental aid to the people there and the experience was life changing. She loves being with family, eating out, going to a good movie, and reading a good book. Camping and boating are also up there on the list, and she loves to travel as well!

Mallory Christensen – Office Manager

Mallory started out as a patient of Dr. Samuel Richey’s in Boise, Idaho, which is where she came from originally after living there for 17 years. When she moved to Utah in March 2006, she joined the Lighthouse team as office manager. Mallory is caring and thoughtful and strives to serve with a joyful heart. She enjoys interacting with our patients and helping them have a good experience.

Mallory and her family currently reside in Pleasant Grove. She and her husband Don are the proud parents of two children. They are so in love with their little girl Sybil and baby boy Ty. When she isn’t busy being Super Mom, Mallory loves writing, playing basketball, singing, writing and arranging music, snow-skiing, and attending college football games (Go Boise State!). She is also an accomplished photographer and thoroughly enjoys her endeavors there. Her most cherished role, however, is being a wife and a mother, and she finds the most incredible joy as she loves and serves her family.

In 2014 Mallory began working remotely from home, where she continues to manage the office and assist our patients and employees with various needs. She is considered the office guru and can answer any question or help with any concern you may have. Contact her via email if you’d like to speak with her at malloryjchristensen[at]gmail.com.
