Our Team
Lisa was born in Chicago in 1961 and grew up in El Paso Texas. After living in Houston for 10 years managing some of the city’s finest restaurants, Lisa made the life changing decision to move to Cozumel in 1991. She introduced the island to in-line skating and opened a rental skate business and snack bar. In 1993 she opened Tia Loli’s tamale factory selling her beloved Aunt Loli’s northern Mexico style tamales.
Cozumel did not have a vegetarian restaurant so she decided to do what she knew best and in 1995 she opened the first Rock’n Java Caribbean Cafe with then partner Karla Porter. It was the first fully vegetarian restaurant and bake shop in Cozumel.
This is when Karla approached Lisa about the serious street dog and cat overpopulation on the island and what she could do about it. At that time City Hall was indiscriminately killing animals by throwing out poison hot dogs in the street in the dead of night. Dogs cats possums raccoons and all other endemic species of the island fell victim to this brutal and inhumane practice of animal control. Karla recruited Lisa and with help from their friends and family they opened the first free spay & neuter clinic and education center in all of Latin America.
Rock’n Java has since diversified and is now one of the go to places for the ex pat crowd and loved by all the island locals. Lisa’s daughter Bianca was born in 1997, raised and educated in Mexico, USA (Texas and Florida) & Germany. She currently lives in NYC. Bianca and Lisa have fostered and cared for everything from dogs, cats, cockatoos, toucans, possums, rabbits, coatimundis and even an elephant. Lisa and her life partner Ernesto opened Rock’n Java Thai Noodle Bar & Sushi in 2008 and have both been active in community outreach and education through the Humane Society and the Rotary Club. Lisa’s focus on sterilization, education and keeping animals safe has kept her involved and active in the Cozumel Humane Society where she has served as President since 2011. Almost 3 decades later the Humane Society of Cozumel Island has become a model for other groups started in Baja, Playa del Carmen, Belize, Cancun, Tulum, Puerto Morelos and Honduras.
“If you don’t like what is happening around you then it is up to you to do what is necessary to change things for the better. It helps that I don’t take no for an answer and you’d be surprised how you can move mountains with a little determination and a lot of cooperation. I credit the community of Cozumel for the strides we’ve made and continue to make and I look forward to a brighter future for domestic animals on the island”.
Gary is a retired Certified Public Accountant. He met his wife Patricia met in Cozumel 25 years ago on a dive trip and returned to the island on a regular basis. In 2014 they bought a condo in Cozumel, and now in retirement they live here for nine months per year. During his years as a tax partner in a Connecticut CPA firm he became active, and has served in officer positions, in many non-profit and civic organizations including the United Way, YMCA, Rotary Club and Chamber of Commerce. He was also on the Board of Directors of Connecticut based Liberty Bank. Gary and Patricia became active with the Humane Society of Cozumel after meeting Ernesto at a Cozumel Rotary Club meeting. They started out by performing dog and cat adoption escort services, and volunteering at spay and neuter clinics. Later Lisa recruited Gary to use his tax and accounting skills, and he now does the contribution receipting and bookkeeping for Friends of the Cozumel Humane Society Inc. (FOTCHS) of which he is currently the corporate secretary. He prepares the annual IRS tax returns and required contribution acknowledgement letters and has become an asset to the Coz HS and FOTCHS.
Melissa Harper grew up in Sheridan, Wyoming. She worked as a financial advisor until returning to college as a non-traditional student where she enrolled in the MBA program at the University of Wyoming while raising three children as a single mother. In 2014 she relocated to the Denver area to work as a commercial business development analyst for an energy transport firm. Her ability to prioritize school tasks while working and raising her children is a testament to Melissa’s drive to better herself and the world around her. After meeting her future husband David, she re-entered the financial industry as a registered investment advisor representative joining his company Cornerstone Financial. Melissa and David were married in May 2016.
In 2020 on one of their many trips to Cozumel Melissa found an abandoned dog living in the jungle. Melissa and Ruffo instantly fell in love and she was ready to take him back to Colorado on the spot. Ruffo was a very ill pup in need of heartworm treatment as well as a myriad of other medications. She and David sought help from the Humane Society of Cozumel Island and together with Lisa Ramirez and foster mom Deb Stein, they began the long road to nursing Ruffo back to health. Once he finally arrived at his new home in Denver, fate again brought the entire family back to the island, this time permanently and full-time. Now fancy Ruffo has his own casa on the playa that he shares with Melissa, David and his canine siblings Max and Breyer.
Melissa has many interests including golf, skiing, scuba, art, traveling, sewing, and writing to name just a few. Her passion for animals and the help she received from the Humane Society of Cozumel Island came full circle when she was asked to join the board of directors as treasurer. “I look forward to many years of helping the HSCI with their efforts to make Cozumel a street dog free municipality and I firmly believe the road to that is through education and proper sterilization.”
Ernesto moved to Cozumel with his family as a small child from Mexico City. After going back to DF to study at UNAM university in the field of Physics he longed to move back to the island he loved as a child. He began volunteering for the Humane Society of Cozumel in his early 20’s while working in the tour industry. In 2009 he opened the Thai Noodle Bar & Sushi, part of the Rock’n Java franchise and joined the Board of the Cozumel HS. In 2012 Ernesto became involved with the local Rotary Club to help the Cozumel community as the Youth Exchange Officer. He served as Rotary Club President in the year 2019-2020 and brought in several clubs from Texas including Greenville and Pflugerville who are still active in the Cozumel Rotary today. Bringing the needs of the islands disabled to these Texas clubs has changed the lives of many families on the island. Ernesto dedicates his time between these two organizations as a way to give back to the island he loves. “I have seen dramatic change in attitudes towards the islands unfortunates and domestic animals and I am proud to have been a part of that change”.
Dr. Mary Holloway discovered her love of caring for animals growing up in rural Ohio. After graduating from The Ohio State University College of Veterinary Medicine, she traded the country for the city and practiced small animal medicine in Chicago for several years before settling in Brooklyn, NY. Her areas of interest are small animal internal medicine, dentistry, and acupuncture. Mary switched gears in 2014 and traded in the high paced big city life to moved to Cozumel. She has been working in the scuba diving industry ever since with partner/husband Paulino Castillo. Together they own and operate Pelagic Ventures Scuba. Mary’s skills as a well trained veterinarian are an asset to the Cozumel Humane Society as the HS clinic hires are usually recently graduated from Veterinarian School. The HS vets are able to consult with her when dealing with a more difficult cases and learn from her experience. Dr Mary lends her surgical skills at all the Cozumel HS massive spay neuter campaigns where 200-300 dogs and cats are sterilized each day. When she’s not busy at the dive shop, she enjoys hanging out with her husband, 3 cats, and dog, as well as biking and exploring the island.
The HSCI welcomed Anabel Himbernon to the staff as General Manager in 2023. After transforming the Humane Society on a day to day basis, Anabel is now an Honorary Board Member. Annabel is an enterprising, creative, highly communicative person with innate leadership skills.

She later graduated with honors from Birkbeck College, University of London, where she studied Arts Management.
She arrived on this island of Cozumel more than 17 years ago and immediately began to contribute as much as possible to make Cozumel a better place. Anabel is an art enthusiast. With theatre as her background she focused her efforts offering the island community high quality plays. Anabel taught, trained and directed a large group of young theatre enthusiasts performing under the name of Creah Teatro. Every moment of her spare time was devoted to helping homeless animals in Cozumel. She continually picked up stray cats and dogs most of whom were sick and in need of immediate attention. With help from private donations, Dr Julio Gutierrez and the Humane Society of Cozumel she was able to heal her rescues and find them permanent homes. Anabel continued her efforts by educating countless families to improve the quality of life of their pets. She provided them with resources for veterinary expenses, transportation and gradually educating owners in disease prevention and permanent well being.
“Cozumel is a different island from the one I arrived to many years ago. I have witnessed with my own eyes the difference the HSCI has made and I knew I had much to offer being part of their team. I have proven to myself time and time again through perseverance, enthusiasm and common sense…one can make any idea or project come true”.

Bob was born and raised in Chicago Ill. He moved his family south to El Paso Texas in 1969 and became a transplanted Texan. Bob serves as the Humane Society of Cozumel Island (HSCI) and Friends of the Cozumel Humane Society (FOTCHS) liaison in the United States. FOTCHS is a registered 501c3 charity. He first became involved with the HSCI in the early years through his daughter Lisa while witnessing first-hand the results the HSCI was making on the island to improve the lives of domestic animals. He helps manage all mailed donations made through our tax-deductible status (FOTCHS) and our U.S. bank account. In the early days before much of what the clinic needed was available in Mexico, Bob mulled down suitcases of badly needed items. Bob is now retired and living in Grapevine, Texas with his partner Julie Quiroz. He spends his time sailing and planning his next dive trip to Cozumel.
“It has been a joy to watch the changes happening in Cozumel over the last 25+ years and makes me proud to know that I have been a small part in helping the Coz HS achieve so much”
Diane found Cozumel as many others before her…in 1991 while cruising with friends. She fell in love with the island, its people and the stunning diving. A year later, she was a proud owner of property in Cozumel (which the Cozumel Humane Society will inherit someday). She married Manfred Wenger in Cozumel in 1997 and together they enjoyed traveling back and forth using Cozumel as their second home. Since 2013, Diane became an advocate for finding homes for the Coz street cats. Every trip down she would bring back cats and find homes for them in the states paying all the expenses. With seven of her own Mexicats Diane continues to help Cozumel by finding street cats a home. She formed the Royal Rescue & Wildlife Sanctuary to house and care for cats while they await their adoption. Every cat is placed in a perfect home in the U.S.A. where they are spoiled everyday. Diane used an inheritance from her late father to help purchase a mobile clinic for the Coz HS where dogs and cats can be sterilized free of charge in all areas of the island.
“Seeing all the stray animals everywhere was very depressing. I use to go to Burger King and buy hamburger patties to feed the animals I saw. Since then, the Cozumel Humane Society was formed and the island has been transformed. Thanks to them, and donations from people like you, they were able to save so many animals and place them in loving furever homes”.
Original Founder Karla Porter. The Humane Society of Cozumel Island is the brain child of Karla. The seeds she planted nearly 30 years ago were just the beginning of what is now a globally recognized organization. In 1995 Karla defied every obstacle and persevered in opening the first free spay & neuter clinic in all of Latin America. Living in Cozumel at the time she could not witness the brutality of how street dogs were disparaged and killed. She set forward her plan and nothing got in her way. Returning from Mexico City with a small grant, she found the land and began construction. Fast forward to today, the HSCI sterilizes 2-3k animals each year and helps thousands more with their outreach program. Karla returned to Pennsylvania and visits the island frequently. She continues to help with fundraising.
We are lucky to have such a force of staff and volunteers who work 6 days a week at the clinic, and sometimes for long days in a row during the sterilization campaigns. At the clinic we have a full-time receptionist and 2 full-time veterinarians, however once our construction project is completed we’ll have space for more resident vets and/or visiting vets.
