Meet The Owners!

Ashley and Dave

Ashley grew up in Stephenville, Texas. She was raised with horses, cows, pigs, FFA, and 4H but was always a lover of the water. She got her open water certification when she was in college as an elective course, and the instructor allowed her mom to come and get certified with her. Ashley worked in geriatric healthcare from 2003-2022 before taking the giant stride into the dive industry with CRD.

Dave was born in Hobbs, New Mexico, but made it to Belton, Texas, in the mid-70s. He got his instructor certification in 1984 at the age of 18 and instantly knew diving was his passion. He has worked in commercial, professional, and recreational diving ever since and has well over 15,000 logged dives under his belt. He also earned his 100T Captains License in 2013. He's owned 3 dive shops prior to CRD in Central Texas, but I-35 (the interstate expansion) took his shop out in 2013, and he began to focus more on diving charters and real estate.

In 2021, after 5 weeks in the French Polynesian Islands (diving almost daily), they realized building a life on the water and diving was their calling. In March of 2022, they decided to start looking to open a dive shop. Memorial Day weekend, Dave got an e-mail about CRD being for sale; sitting at home in Texas, everything made sense. They came down the first weekend in June and instantly knew this was right. Their journey with Conch Republic officially started July 1st.

We are so excited to share our love and passion for the ocean with those who want to see what's under the sea!!!

Thankful, Grateful, Blessed

Captain & MSDT

Carlos Cirilo

Carlos began diving recreationally in 2012 while serving in the U.S.N. overseas. Qualified by a Naval Diving officer who was both a NAUI and PADI instructor. This made his qualification experience unique to say the least. After officially completing his AOW, during his first Open Water dive he encountered Whale Sharks. From that day he knew that he will be doing this for the rest of his life and purchased all dive gear that same day! His passion is helping others experience what he has underwater, especially within the Adaptive and Veteran community!


Marly Silvestri

Marly began diving in 2019 after her brother got certified in Indonesia and talked her into trying scuba. She heard humpbacks singing off Hawaii during her OW and was immediately hooked. She spent most of her early dives in Colorado reservoirs and the cold waters of California's kelp forest. Marly completed her DM in Colorado and then decided to complete IDC in the Keys where visibility exists. Ultimately, she chose not to return to Colorado and remains in the keys teaching and guiding.
