He regularly spent 12 hours a day on campus, cutting back only\u00a0 to pursue his master\u2019s degree in educational leadership from Loyola Marymount University in Los Angeles. He would study online late into the night until his illness required him to take a leave of absence from teaching in March 2025. But he finished his master\u2019s, proudly walking in cap and gown at the ceremony in Los Angeles on May 18, 2025, one day after the birthday of his sister.

Both his parents were immigrants and worked full time. His father, Edgar Sr., worked a series of jobs and ended up a P.E. teacher in the San Francisco Unified School District. His mother was an administrator at San Francisco State University and later was appointed Nicaragua\u2019s Consul General in San Francisco.<\/p>\n<p>Edgar, called Emilito by his family and Eddie by his friends, attended Fairmount Elementary and St. Anthony parochial school. At age 9, he was on the sidewalk in front of the family\u2019s\u00a0 house on Coso Street when he witnessed his sister getting hit by a car that had lost its brakes and rolled backward down the hill. She was stuck underneath it and her little brother ran to get help, which she said \u201csaved my life because nobody else was around.\u201d Her brother remained protective of her after that incident, which put her in the hospital for a month, she said.\u00a0<\/p>\n<p>After graduating from St. Anthony, he attended Riordan, the boys high school run by the Brothers of Mary in the Ingleside district across from City College of San Francisco. Beteta, who was nicknamed Gumby on account of his hair sticking up like the rubber toy figure, went out for the freshman baseball team.<\/p>\n<p><img alt=\"Edgar Beteta's baseball photo from the Archbishop Riordan yearbook, 1985.\" loading=\"lazy\"   style=\"aspect-ratio:2 \/ 3\" class=\"x100 y100 opc bgpc ofcv bgscv block bg-gray200 mnh0px fill\"\/><\/p>\n<p>Edgar Beteta&#8217;s baseball photo from the Archbishop Riordan yearbook, 1985.<\/p>\n<p>Courtesy of Riordan High School<\/p>\n<p>He was a second baseman and right-handed pitcher, both a starter and reliever with a wicked curveball that he was willing to teach to his teammates even if they ended up taking innings away from him.<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>\u201cI knew he was going to be a coach,\u2019\u2019 said Nick Castora, a centerfielder with Beteta on the JV and varsity teams, which practiced and played most of its home games on an infield littered with\u00a0 broken glass and an outfield pocked with gopher holes at Crocker Amazon Playground. Beteta would cram five players and their gear into his 1972 Volkswagen Beetle for the commute to Crocker Amazon and the school\u2019s other field, Balboa Park.<\/p>\n<p>\u201cHe was always there as a guide,\u201d said Castora. \u201cHe loved to play, but he had something in him that just loved helping people out.\u201d\u00a0\u00a0\u00a0\u00a0<\/p>\n<p>Riordan has always offered to teach anyone a musical\u00a0 instrument, and as a sophomore Beteta took up the alto sax with his buddy Randy Bickel. They stuck with it side by side for three years, playing in the\u00a0 pep band in yellow windbreakers with the Riordan crest to fight the night chill during rivalry football games against Sacred Heart, at the old Kezar Stadium, and basketball games against Sacred Heart or St. Ignatius in Kezar Pavilion.<\/p>\n<p>During sophomore year, Beteta started noticing that his fingers were sore when he came home from baseball practice. The symptom led to a diagnosis of\u00a0 lupus, a chronic autoimmune disease that causes widespread inflammation. His sister could see the swelling in his face in class pictures.\u00a0<\/p>\n<p>\u201cHe may have missed classes but he never complained,\u201d said his sister. \u201cHe was very dignified and courageous.\u201d\u00a0<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>At the same time, he was navigating his parents\u2019 breakup.

He eventually transferred\u00a0 to San Francisco State, where he earned a\u00a0 bachelor\u2019s degree in sociology in 1994.<\/p>\n<p>\u201cHe was always very smart,\u201d his sister said. \u201cI remember watching \u2018Jeopardy! \u2019 with him, and he knew all the answers.\u201d\u00a0<\/p>\n<p>\u201cYou need to be a teacher,\u201d she told him.<\/p>\n<p>So he became one, earning his teaching credential from Notre Dame de Namur in Belmont, and starting out as a substitute in the San Bruno Park School District. He then was hired full time to teach seventh grade at Our Lady of Mercy in Daly City. When he was hired at Riordan, about 20 of his former Our Lady of Mercy students came with him, helping form the first coed class.<\/p>\n<p>\u201cI just loved how outgoing and kind he was,\u201d said Adrieana Diokno, who had Beteta as a teacher for two years at Our Lady of Mercy followed by two years at Riordan. \u201cHe was like a friend to all of his students and he made class really fun and engaging.\u201d\u00a0<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>Beteta\u2019s lupus was in remission when he met Stephanie Santa Maria in the mid-1990s.

They were married in 2002.\u00a0<\/p>\n<p>One year later, Beteta suffered kidney failure that required dialysis. With help from family, the Betetas bought a townhouse in the Serra Highlands neighborhood of Daly City.

That was a passion of his.\u201d<\/p>\n<p>Because he was immunocompromised, Beteta often wore an N-95 mask long after the COVID-19 mandate was lifted.\u00a0\u00a0<\/p>\n<p>But as his illness progressed, he had to go out on medical leave. He promised his students he\u2019d\u00a0 be back but several rounds of chemotherapy took a toll\u00a0 and he was hospitalized after a fall. On Feb. 17, his old gang of the Riordan boys were summoned by Amelia and they all drove in from Antioch, Shingle Springs, Concord, Pleasant Hill and Rohnert Park. beyond. Six of them crowded into one hospital room on Ash Wednesday, Feb. 18 and stayed with him until the end.<\/p>\n<p>\u201cHe passed in front of all of us, and we notified the nurse,\u201d said Bickel.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/p>\n<p>After his death, Rassam was asked by administrators to make a video tribute to him. He reached out to the alumni community and got enough video testimonials to form a 45-minute reel.
