Board of Directors

Our Board of Directors donate their time to the Texas Cave Management Association because they believe strongly in our mission and understand the importance of protecting caves and karst resources. They are well-established in the caving community and have numerous ties to other conservation agencies and nonprofits. Some have decades of experience serving on the boards of these conservancies. Our board members also come from a wide range of backgrounds, ensuring that we have a diverse culture and wide knowledge base to achieve our goals.

Interested in becoming a TCMA board member?

The TCMA Board of Directors is open to anyone who has a passion for conservation. At times, we may have a need for specific qualifications, such as land trust experience or nonprofit fundraising. However, as long as you have an interest in caving and cave conservation, you are welcome to apply.

Nominees are selected each summer, and elections are held in the fall. Directors are elected for three-year terms, and can serve for two terms in a row. After the second term, directors must take a mandatory break before running again. Officers must be board members and are elected by the board at the beginning of each year.

Some of the responsibilities of TCMA directors include:

  • attending at least 50% of board and member meetings,
  • representing TCMA in the community, such as presenting programs to civic or business groups,
  • participating in fundraising through events, presentations, grant writing, mailings, etc., and
  • participating in TCMA’s annual evaluation and planning efforts.

If you want to become part of the group that actively protects our Texas cave resources, and help to direct and shape our conservation efforts, please contact any of the directors below for more information about becoming a TCMA board member.

Officers and Directors


Joe Ranzau

Jan. 2016–Dec. 2018

In addition to serving previous terms as a director and an officer of TCMA, Joe Ranzau has also been an officer of the Texas Speleological Association and the Bexar Grotto.

Mr. Ranzau’s caving life started 19 years ago as a tour guide at Cave Without a Name. Some cavers from the Bexar Grotto would come out to go play in the stream passage. Mr. Ranzau wanted to know what was around the corner, so he joined in! From there, he quickly joined in the fun around the state at various projects like Kickapoo Caverns and Colorado Bend. Pat Copeland and other cavers lit a passion in him for cave conservation and restoration. This passion has taken him caving in many special places around the US, Mexico, and Belize.


Linda Palit

Jan. 2018–Dec. 2020

Linda Palit started caving in the 1980s, and gradually it turned from an interest to a passion. As with most passions, caving has led to her participation in different caving groups, and her functioning in different roles. She has held grotto offices, held state offices, helped organize national and international conventions. Just as importantly, she have done some wonderful caving.

One of the biggest changes in caving since she began has been the relentless restriction of access to caves. She believes TCMA can impact this, and that contributes to her interest and work with TCMA.  Protecting caves and providing access to caves is one reason TCMA exists; she believes in that mission.

Several things she would like to work on with TCMA are the acquisition of more caves, the improvement of communication with members, and the incorporation of more people into the day-to-day activities of the organization.


Lindsey Adamoski

Jan. 2017–Dec. 2019

Lindsey Adamoski entered her first cave at the age of 3 years, and has been caving regularly since early 2015.

Mrs. Burrell has held office in the TSA in the past. She truly appreciates all of the conservation work that has been done by the TCMA.

In addition to caving, she also enjoys hiking, camping, backpacking, rock hounding, and canoeing. She is married to Mike Burrell, who is also a caver. They live on the property of Cave Without a Name in Boerne, Texas where her husband has been working for several years.

In 2015, she won the Chuck Stuehm award for exuberant activity as a new caver for her grotto, the Greater Houston Grotto. She has been on expedition exploring, hauling tanks and surveying to a depth of 400 meters. Ms. Morton admits openly to having fear before every cave, but she walks through the fear every time. Because she has had so many great opportunities that have enriched her life greatly, she loves to give back to the activity.

Greg Mosier

Jan. 2018–Dec. 2020

Greg Mosier has been an avid lover of the outdoors and nature as far back as he has memories. His interest in caves begin at about the age of 12 when he entered his first wild cave which happened to be Wurzbach Bat Cave. That began a never ending love of the adventure of exploring underground which ultimately led to a Degree in Geology and then to joining the Bexar Grotto in the early 90s. Subsequently the responsibilities of life caused Greg to drift away from the caving scene.

Greg reconnect with the caving community by rejoining the Bexar Grotto in 2013, and more recently the TCMA and the TSA, participating in many volunteer efforts such as taking new people into caves such as Robber Baron Cave, and several project and survey trips to Deep Cave. Greg was elected the Chairman of Trips and Quarter Master for the Bexar Grotto in 2017 and has organized and led trips for Bexar Grotto members to Cave Without a Name, Snookie’s Cave, and Deep and Punkin Preserve. Greg also has led the effort to organize a project with Comal County to allow for cave exploration at Kleck County Park and is the trip leader for this endeavor.

Greg’s principle desire is to continue to expand upon his project oriented caving efforts to gain knowledge to use as a tool for raising the awareness of the general public about the importance of caves, their sensitivity, and to eventually tie this into a wider conservation effort.

Denise Prendergast

Jan. 2016–Dec. 2018

Denise Prendergast has been a caver for nearly 20 years. With a bachelor degree in Geology, she has a keen interest in resource conservation and the outdoors.

Ms. Prendergast is currently an officer of the UT Grotto and a past Secretary of the Texas Speleological Association.

Juliana Rincón

Jan. 2018–Dec. 2020

Juliana Rincón went into her first cave in her teens, discovering that she actually enjoyed crawling in water passage with low air space and bats flying in her face. In 2011 she joined Anthros Grotto in Costa Rica, where for a few months she learned about caves and caving. After a bit of a hiatus, she eventually made it into Dallas Fort Worth. In 2016, she won the Chuck Stuehm Award for Outstanding New Caver and in 2017 she was elected as the DFW Grotto Chair.

Mrs. Rincón is a member of the National Speleological Society (NSS), the Texas Speleological Association (TSA) and is an active cave cartographer, both assisting in the digitalizing of cave maps and as a surveyor and sketcher.
