and the ability to recognize what was right were clearly driving forces in Sergio’s life. He was also the
kind of person who could respect a “do not disturb” sign, whether it was real or implied. He was
analytical and observant, with an ability to be simultaneously spontaneous and keenly perceptive.
Sergio was modest in his actions and extremely literal in his thoughts and in the manner in which he
communicated with others. When Sergio said something, he meant it. All those who knew him
appreciated this trademark quality.
Sergio was born on June 26, 1992 at Olive View - UCLA Medical Center in Sylmar, California to his
mother, Dora De La Rosa. Sergio was raised in Las Vegas, Nevada. Even as a small child, Sergio wanted
to understand what was right and what was wrong in any given situation. As Sergio grew older, he
realized the importance of being treated fairly, and in return, he treated everyone around him the same
way. This belief in fair play served Sergio well throughout his life and despite his natural shyness; he
enjoyed a solid group of friends.
Since Sergio sought to treat those around him with respect, he often found himself in the role of
playing peacemaker within his family. He was comfortable in working through the types of sibling rivalry
situations that quite often occur, because he loved the challenge of conflict resolution. He would look at
the most reasonable and practical ways to settle any disputes. He had one younger sister, Kathy. Sergio
was constantly involved in activities with his sister. Sergio and his sibling had the typical rivalries while
growing up, but they shared many life experiences.
During his childhood, family and friends viewed Sergio as a quiet and reserved person with what
most would consider a calm and tranquil demeanor. In fact, he was a fairly curious child who had the
ability to entertain himself and didn’t require much in the way of outside stimulation. A great deal of
Sergio’s free time was spent learning how and why the things around him worked. He was an active
child who loved being outdoors and absorbing all the sensory input that nature could provide. In his
spare time, he liked collecting Pokémon Cards, watching movies (especially sports related movies),
playing at the park and watching Dragon Ball Z. Sergio's memorable achievements included straight A's
throughout elementary school.
The fact that he was curious was an asset to Sergio while he was in school. He possessed strong
study skills and good concentration. He relished the task of scrutinizing problems, investigating all the
options, and then solving them. Sergio enjoyed tackling the project that was right in front of him and
working it straight through to its conclusion. Sometimes, he would become so involved in the process of
problem solving that he would lose awareness of his surroundings. Experience was Sergio’s best
teacher. He graduated from Southeast Career Technical Academy in 2010. In high school he enjoyed his
Drafting courses the most.
Those who didn’t know Sergio well might have thought him to be objective and somewhat
emotionally detached, but family and friends who were close to him knew that he was full of jokes and
quick witted. Sergio’s good friends tended to be “thinkers” like himself. Even though the circle of
friends was somewhat small, it was a strong and loyal group, and Sergio liked nothing better than to
spend his free time with them. Sergio was well known for always being up front and open, never hiding
his true feelings, qualities that drew deep loyalty from his friends because they understood and
appreciated him for the person he was. Another quality that people admired in Sergio was his ability to
link cause and effect and apply the appropriate connection in his assessment of any new situation.
While growing up, some of his best friends were Eddy Yanez, Hugo Enriquez, Marley Williams, Travis
James, and John Patrick Clemente. Later in life, he became friends with Humberto Jaimes, Tyler
Johnson, Willie Hallman, and Eduardo Bueno.
This same loyalty and up front honesty Sergio shared with his friends carried over to other aspects of
his life, including his relationships with his family. On April 6, 2019, Sergio exchanged wedding vows
with Karen Paola Del Toro Alvarez at the St Anne Catholic Church of Las Vegas, Nevada. The marriage
became a solid and loving relationship, due in part to Sergio’s skill at bringing fresh energy and clarity to
meeting Karen's needs. He was a great listener who enjoyed the couple’s “together” time, especially
when it came to celebrating special occasions.
As the family grew, Sergio was easily able to adapt to the changes and challenges of parenthood.
Sergio was never impulsive in dealing with family problems. Instead, he would carefully think things
through before implementing the solution in a logical and objective manner. Sergio was a strong, clear
communicator who excelled at eliminating confusion by making matters crystal clear to all those
involved. At the same time, Sergio’s inventive nature could turn any task into a fun and creative time
with family or friends.
In his work life, Sergio was the kind of person who had no difficulty in taking on a project and seeing
it through to its completion. He excelled at dealing with those pesky details that can derail some
people, and once he understood exactly why he was working on a project, he could plow full steam
ahead. For Sergio, being able to grasp the logical components of any task was significant to him in
appreciating its importance. Even if he worked alone on an assignment, Sergio was able to incorporate
and welcome new insights from co-workers, and he would readily use them if they improved the
process. His primary occupation was Law Enforcement. He was employed for 4 years at Nevada
Department of Corrections and almost 2 years at Las Vegas Metropolitan Police Department. Sergio
always made the effort to be a team player, doing what was necessary to get the job done.
Sergio’s curious and inquisitive nature influenced his choice of leisure pursuits as well. He applied his
strong concentration and analytical skills as to how things worked to his choice of activities. He
particularly enjoyed the competitive yet bonding time his hobbies provided. His favorite pursuits were
playing / watching sports, collecting Pokémon and sports cards, shooting with friends, spending time
with his family and cooking. Sergio was content to enjoy his hobbies alone but was also willing to share
his interests with others.
Sergio had the ability to stay calm and the determination to do what was necessary to get the job
finished, traits that helped him enjoy sports. In high school, Sergio played baseball. Recreational sports
included softball, baseball, and basketball. Sergio was also a major sports fan and enjoyed following his
favorite events whenever he got the opportunity. Tops on his list were baseball, football, and
basketball. The New York Yankees was his favorite team.
Sergio was an asset to any organization he joined. In many ways, he was a man of action who would
rather tackle a job than spend time chatting about irrelevant things. He worked well on small
committees and excelled at focusing on the important details without getting bogged down by the
unnecessary parts of an assignment. In high school, Sergio was a member of the Student Organization
of Latinos.
Religion and faith were important to Sergio. He held dear the faith and values he derived from his
beliefs. He was a member at St John Neumann Catholic Church.
Because he was a man who let his actions speak for themselves, Sergio didn’t find it necessary to
brag or boast. But it wasn’t always possible for him to conceal his accomplishments. Others who
recognized his achievements made certain that he was honored for them. Some of his most prestigious
awards included being Valedictorian for his Metro Class Academy in 2019.
Sergio passed away on June 21, 2021 at Las Vegas, Nevada. He is survived by his wife, Karen Del Toro
Alvarez; his daughter, Mia; his mother, Dora De La Rosa and his sister, Kathy Delgado. Services were
held at Palm Northwest Mortuary. Sergio was laid to rest in Palm Northwest Cemetery.
Sergio strongly believed that talk is cheap. He was the type of person who would show others his
feelings through his actions. He was practical and realistic but was able to be flexible when the need
arose. He had a curiosity about the things around him and tried to experience life directly rather than
sit back and talk about it. The experiences he treasured most were those he shared with his loved ones.
