A profile shaped by work, family, and distance
Seth Stoppelmoor’s public footprints show structure rather than noise. Professional directories, family records, and sporadic social posts bear his name. His profile has edges, not polish. A life sketch made of functional lines, like a steel-beam bridge instead of paint.
His public image is most clearly linked to Texas and cybersecurity and IT. CISSP is a critical security accreditation, and his career shows leadership in cyber defense and infrastructure. He appears to have spent years inside modern organizations, keeping the lights on and the doors secured, in the public information I read.
That important because working cybersecurity is often unseen. A firewall guards silently. A secure network is a clean hallway. Seth Stoppelmoor seems to live in a world where duty is judged by not breaking.
Career identity and professional footprint
Publicly available details associate Seth with a senior cyber security role at Pedernales Electric Cooperative. His broader work history, as reflected in profile summaries, suggests experience across federal and enterprise environments, including work tied to the IRS and other technical organizations. His professional background also points to familiar but important disciplines such as networking, disaster recovery, virtualization, Windows Server, Microsoft Exchange, PCI DSS, ITIL, project management, and VPN systems.
That is a wide toolbelt. It suggests not a narrow specialist but a person who has lived in the crosscurrents between policy, systems, and operations. Some professionals build one tower. Others maintain the entire city grid. Seth appears closer to the second category.
A compact view of the public record looks like this:
| Area | Publicly visible detail |
|---|---|
| Name | Seth Stoppelmoor |
| Location | San Antonio, Texas area |
| Field | Cybersecurity and IT |
| Credential | CISSP |
| Education | University of the Pacific |
| Public role | Director of Cyber Security |
| Workplace | Pedernales Electric Cooperative |
There is no public financial profile that is reliable enough to treat as fact. I do not see credible evidence for salary, net worth, or investment history. What does emerge is a picture of professional steadiness, the kind of career that builds value through consistency rather than spectacle.
Family roots and personal relationships
The family story is one of the strongest parts of Seth Stoppelmoor’s public footprint. He is linked to a known family line with several members visible in public records. The family connections center on his parents, siblings, and extended relatives, including one especially recognizable name.
Marion Wayne Stoppelmoor
Marion Wayne Stoppelmoor is identified as Seth’s father. Public family records also connect Marion to Cheryl Ladd, which places him at the center of a family line that has drawn attention over time. He is described in public biographical material as a railroad engineer. That detail is vivid to me. It suggests precision, routine, and long-distance discipline, a life of schedules, motion, and dependable work.
Dolores Mae Stoppelmoor
Dolores Mae Stoppelmoor, also referenced in public material as Delores H. Katz or Dolores Katz Stoppelmoor, is identified as Seth’s mother. Her obituary records a life beginning on March 4, 1933, in Huron, South Dakota, and ending on August 17, 2018. It names several children and anchors the family tree in a concrete way.
From the public material, I can identify the following as her children:
| Family member | Relationship to Seth |
|---|---|
| Cheryl Ladd | Sister |
| Mary Ann Eichman | Sister |
| Brian Stoppelmoor | Brother |
| Seth Stoppelmoor | Self |
That list matters because it shows the family as a whole, not just Seth in isolation. He is one branch on a larger tree with a sturdy trunk and several visible limbs.
Cheryl Ladd
Cheryl Ladd is the most publicly visible member of the family. She is Seth’s sister. In public life, she is widely known as an actress and singer. That makes the Stoppelmoor family unusual in one sense. It spans both the quiet labor of technical work and the bright theater of entertainment.
I find that contrast striking. One sibling moves through systems and security. Another moves through performance and public attention. It is like a house with two windows, one looking into code and control, the other into stage lights and applause.
Mary Ann Eichman
Mary Ann Eichman is identified as another sister. Her public footprint is smaller than Cheryl’s, but family records place her plainly within the sibling group. That visibility is limited, yet still important. She helps complete the shape of the family, and family identity depends on the whole frame, not only the famous pieces.
Brian Stoppelmoor
Brian Stoppelmoor is identified as Seth’s brother. Public records place him in the family alongside Seth, Cheryl, and Mary Ann. In the family structure, Brian adds another point of continuity, another son of Marion and Dolores. The family appears close enough to be traceable, but private enough that few details beyond the basics are widely public.
Extended family
The public genealogy material also points to grandparents and older roots. On the paternal side, Otto Aeilt Stoppelmoor and Irene Leona Day appear as grandparents. On the maternal side, Ira Katz appears as a grandfather. These names help place the family in a longer timeline, one that stretches beyond public visibility and into older generations.
Public traces, recent mentions, and what they suggest
Although tiny, Seth’s recent public mentions reveal texture. A 2020 social post shows his password security interest. Online posts in 2023 and 2024 show him discussing technical issues, work sharing, and leadership. In 2025 and 2026, group postings and comments leave a social trace.
That pattern tells me something basic but useful. Seth rarely makes headlines. He’s more like a nighttime window lamp—lit but not for exhibition. Public life confirms his professional and social presence but does not reveal his private life.
Here is a brief date line of the visible record:
| Date | Public trace |
|---|---|
| 1933-03-04 | Dolores Mae Stoppelmoor is born |
| 2018-08-17 | Dolores Mae Stoppelmoor dies |
| 2020-02-14 | Seth comments publicly on password security |
| 2023-04-09 | A photo shows him at an open mic event |
| 2023-05-26 | He shares a job-related post |
| 2024-04-03 | He comments about repeated bot calls |
| 2024-09-14 | He comments on leadership |
| 2025-12-06 | He appears in a group welcome post |
| 2026-04-07 | He appears in another group comment |
A family shaped by contrast and continuity
What stands out most to me is the contrast within the family. Marion represents steadiness and technical labor. Dolores represents the maternal center that held the household together across generations. Cheryl brings public visibility and artistic renown. Mary Ann and Brian complete the sibling set. Seth, meanwhile, occupies the practical middle ground, a professional life built around security, systems, and controlled risk.
Together, they form a family with both public familiarity and private depth. The family story is not a single bright headline. It is a layered photograph, part formal portrait, part candid snapshot. The edges matter.
