Our Doctors:

Dr LaDuca will become CPMG’s head physician in July, 2023. She comes to us from more than 15 years in academia, teaching new physicians at the Long Beach Memorial Family Medicine Residency program. She is fantastically overqualified to run our little clinic but has amazing ideas and plans. She is brilliant, experienced, wise and compassionate. She is committed to her future role as the “community doctor” and sees each patient as a complete individual. She believes in wellness and health, not just treating disease. She is trained in “Lifestyle Medicine”, amongst numerous other accomplishments. She and her husband already own a home in Paso Robles and she is excited to be moving full-time to the Central Coast.

Her bio includes the following, incomplete listing, as her accomplishments are too numerous to list here:

Dr. Kat Estopinal grew up in Houston, Texas. She attended Georgetown University in Washington, DC where she received her BS in Biology of Global Health. After graduation, she completed two years of service work, first with the Jesuit Volunteer Corps in Sacramento, CA then with AmeriCorps in Austin, TX.

While in medical school at Texas A&M College of Medicine in Temple, TX, she joined the US Army via the Health Professions Scholarship Program. During her residency at Carl R. Darnall Army Medical Center in Fort Hood, TX, she built a foundation of full-scope Family Medicine which she continued at her next duty assignment at Brian D. Allgood Medical Center in Camp Humphreys, South Korea.

Dr. Estopinal utilizes evidence-based medicine to provide preventative and wellness medical care for all ages from newborn to geriatric patients. The Jesuits’ motto cura personalis (caring for the whole person) particularly resonates with Dr. Estopinal. As a Family Medicine doctor, she values taking care of the whole family, as well. She has significant experience with women’s health, sexual assault medical care, and transgender medicine.

Dr. Estopinal moved to Cambria in January 2023 with her husband and young son. They are excited to make Cambria their home!

Dr. Kat Estopinal 

Karen Chestnut was born and raised in San Luis Obispo, CA. She is a third generation San Luis Obispo native. She graduated from Cuesta College Registered Nurse Program and worked in the Emergency Departments at Twin Cities, Sierra Vista and French Hospital as an RN. She worked on the side while working in the Emergency Departments at San Luis Ambulance as a Critical Care Transport RN.

Wanting to continue her education, Karen went back to school at Sonoma State University and graduated from the Family Nurse Practitioner Program. For about two years after graduation she worked in Oxnard at St. John's Regional Hospital as a Nurse Practitioner. She was then recruited by the Medical Director of the Emergency Department at French Hospital to help establish an Advanced Practice Provider program at French and Arroyo Grande Hospital. The program has been successful and is currently still in practice at French and Arroyo Grande Hospitals. 

Fortunate to live and work in the community that she grew up in, she has cared for many people and families she has known her entire life. The choice to move into Family Practice was easy as this was a way for her to slow down and spend time with her patients.

Karen lives one block from her father. He still lives in the house she grew up in. Her mom lives in San Luis Obispo as well as one of her sons. She has two other children that live on two separate ranches in Creston. Karen has horses, dogs, chickens and one cat. She enjoys everything that has to do with the outdoors.
