Seidlitz Education

What Seidlitz Education does

Seidlitz Education LLC is a privately-held educational publishing and professional development company founded in 2005 by John Seidlitz, headquartered in San Clemente, California. The company serves K-12 school districts and individual teachers, with a sharp focus on supporting English Learners, emergent bilinguals, and multilingual learners through research-based instructional strategies. Its core offerings comprise three integrated lines: (1) a catalog of 40+ specialized books authored by practicing educators covering topics such as bilingual/dual-language instruction, the proprietary 7 Steps methodology, QSSSA conversation structuring, newcomer support, and Texas ELPS standards; (2) professional development services including on-site and virtual trainings, instructional coaching cycles, school leadership rounds, and ongoing PD programs delivered by a roster of senior educational consultants; and (3) The Visual Non-Glossary, a web-based digital platform providing structured visuals and sentence stems aligned to TEKS and NGSS standards across Math, Science, and Social Studies, sold as $100/year annual subscriptions per subject area.

The business operates a hybrid go-to-market combining direct-to-consumer e-commerce book sales (one-time purchases priced $7.95-$40) with enterprise-style PD service delivery to school districts via contact-form bookings. Marketing is multi-channel, including the Seidlitz Blog, the Boosting Achievement Podcast, a webinar series, downloadable free resources, conference events, and organic social media. The company maintains no disclosed external funding, parent company, or acquisition history, and is organized as an LLC with a 34-person team structured around a C-suite led by CEO Dr. Mónica Lara, Chief Product & Marketing Officer Anna Matis, Chief Learning & Innovation Officer Nancy Motley, and Chief Digital Officer Dr. Stephen Fleenor, supported by an extensive network of educational consultants. Pricing tiers reflect a one-time book revenue stream layered with a nascent recurring digital subscription revenue stream from The Visual Non-Glossary.

Expansion highlights6 records

Direct peers

• Benchmark Education Company: Independent publisher of K-8 literacy and bilingual/dual-language instructional materials with extensive professional development services for school districts. Closest direct competitor to Seidlitz's book + PD + digital model in the EL/bilingual space.
• Estrellita: Publisher of Spanish early literacy and bilingual instructional programs for K-2, with teacher training and PD offerings. Comparable niche specialization in Spanish-language literacy development that mirrors Seidlitz's bilingual and EL focus.
• Brookes Publishing: Independent publisher of special education, literacy, and EL instructional resources with PD offerings for educators. Comparable in being a niche independent publisher serving educators of diverse learners including ELs, with similar book-plus-PD revenue model.

Broad incumbents

• Heinemann Publishing: Major educational publisher (subsidiary of Pearson) offering K-12 literacy, EL, and content-area books alongside extensive professional development services. A larger incumbent that overlaps with Seidlitz's PD and book offerings but at much greater scale.
• Imagine Learning: Large EdTech provider of digital literacy, EL, and math programs for K-12 with district-wide licensing and teacher PD. Overlaps with Seidlitz's Visual Non-Glossary digital subscription model and EL/bilingual audience but at significantly larger scale.
• Lexia Learning: EdTech provider of literacy and English language learning programs (part of Cambium Learning) sold through school district contracts. Comparable in targeting EL teachers and using digital subscription delivery, but operates at much larger scale.
• Scholastic Education: Major K-12 publisher and PD provider with bilingual and EL programs reaching most US school districts. Broad incumbent with overlapping product categories including books, digital resources, and teacher training.
• National Geographic Learning: Publisher of K-12 EL, world languages, and content-area instructional materials (part of Cengage). Comparable in publishing EL/bilingual textbooks with aligned PD offerings, though at significantly larger scale and broader geographic reach.

Emerging players

• Colorín Colorado: Free PBS/WETA online resource providing strategies, tips, and book recommendations for educators of English Learners. Adjacent niche resource with similar target audience but operates as a free nonprofit rather than commercial publisher.
• EL Education: Nonprofit K-12 curriculum and professional development provider offering language arts and EL-aligned instructional materials with cohort-based PD for districts. Comparable PD-and-curriculum model aimed at similar school district buyers.
