Kathleen grew up in the jewelry business, learning from her father’s passion and dedication to excellence. Today, she proudly carries that legacy forward with a fresh perspective, guiding George Thompson Diamond Company with both heart and vision. In 2025, Kathleen was honored by Jewelers of America as one of the Top 40 Retailers Under 40 in the country, a prestigious recognition of her leadership, innovation, and impact within the jewelry industry.

When not at the store, Kathleen enjoys spending time with her family and supporting the local community and playing tennis.

Charlie Kimball is the co-owner of George Thompson Diamond Company and brings years of expertise to the business.

Kam started part time after school running errands, and after graduation began working full time in the office, supporting sales and anywhere else she was needed, growing into her current role as Store Manager.

A Ventura native, Kam has so many wonderful stories from her time at George Thompson Diamond Company and loves the industry. She's seen many couples who came in to buy their engagement and wedding rings return with their babies and years later bring those kids in to buy their own wedding rings. One of her favorite custom jewelry pieces was for a long time friend who came in wanting to create a beautiful pendant with our designer out of her mother's diamonds and stones. Kam loves spending time with her family, camping, backyard barbecues and watching her sons play sports, and says the people she works with are like family too!

Myrna deeply appreciates the leadership of Kathleen and Charlie Kimball and finds joy in the inclusive atmosphere they foster. One of her favorite traditions is the monthly birthday celebration for staff, an event that honors everyone and ensures no one is left out, making her feel cherished and valued.

Outside of work, Myrna loves spending time with her family, exploring new restaurants, and traveling, and spending time with her church friends and family. She is immensely proud of her three wonderful children, who are pursuing their careers across the country. Myrna also serves as the treasurer for the Filipina American Group in her community and is an avid fan of the Dodgers, Lakers, and LA Kings.

Myrna's dedication, warmth, and extensive experience make her a vital part of the George Thompson Diamond Company family.

Born in St. Louis, she moved to California in 1988, graduated from Rio Mea while getting her industry start selling jewelry at the Esplinade Mall and completed Diamond Grading at GIA in 2003. Sue says this job feels like family and along with loving what she does it's a bonus to know she is a part of something so special.

Her favorite customer story is from a couple married for 70 years, the husband climbed into a bedroom window and they traveled to the next town to be married because her parents did not approve. He purchased his 70th anniversary ring with us that day! There are also special moments like taking a client's grandmother's diamond engagement ring and including it in the design for the granddaughter's engagement ring. Sue is happily married to husband Murray and you may just find them shooting pool when not with their wonderful children Rachel, Allison, Emma, Isabella and Cash.

Terry also grew up in the business in the Oxnard area, attending the Fashion Institute of Design and Merchandising while working at Bullocks and Macy's, returning to work at her dad's business Oxnard Jewelers. There is a real family feel at the George Thompson Diamond company and Terry is very grateful for the opportunity to work with this group, our team often sees each other more during the day than their own families.

There are so many wonderful customer stories over the years it's hard to pick just one, but Terry has developed several special friendships with customers and remembers a special time that a client was interested in upgrading her original wedding set with a larger diamond but original rings that she couldn't wear due to arthritis in her fingers. Our jeweler came up with the idea to add a special snap shank that would open so she could easily put on her rings and incorporated the larger diamond as well, a dream come true for this happy customer! Terry enjoys spending time with her family, traveling, and being outdoors.

Born in Chiang Mai, Thailand and family friends for years with George and his wife Toi, she's now also in charge of our social media accounts, as well as answering customer questions, supporting repairs and completing quality inspections. Though she's spent time in Pennsylvania and Texas, Natalie grew up in California and found her passion for jewelry after attending Ventura College and especially loves the great support system she has with her co-workers because she's learned so much from their collective years of experience.

George once told Natalie that a wedding ring is one of the most important purchases of someone's life and she really takes that to heart, putting her all into any custom ring requests and making sure she fully understands what her customer envisioned so she can bring their dream ring to life! When Natalie isn't at work you can find her chasing waterfalls, grabbing coffee with friends, exploring hiking trails and collecting sea glass and unique rocks t...

Misty got over 30 years experience in the jewelry industry and has a lot of clients who remember her from her earlier days in the business.

For Misty, working with people is her favorite part of what she does and one of her fondest memories is creating a beautiful custom ring for a client from the three rings that her mom had left her, feeling it is always so special to create something new with sentimental family pieces. When she's not at George Thompson Diamond company, you'll find her spending time with her grandchildren and gardening.

Robert believes in the power of connection, using each client interaction as an opportunity to build lasting relationships. His favorite aspect of working at George Thompson Diamond Company is the cohesive, family-like atmosphere. Unlike his previous retail experiences where turnover was high, Robert appreciates the long-term bonds he has formed with his colleagues, who feel like brothers and sisters.

A particularly memorable moment for Robert was when a couple visited the store with their diamond. He was able to provide them with detailed information about their piece, leaving them intrigued and appreciative of his expertise. Robert understands the importance of making clients feel comfortable and valued, fostering a trusting environment where they can share their special jewelry pieces.

Outside of work, Robert has a passion for collecting vintage hand tools and rare, select tequila bottles. He enjoys the hunt for special tequila bottles that are no longer in production and treasures spending time with his family and friends.
