Meet Our Educators
Vice President of Educational Services
My name is Anadri Ortiz. I was born in Venezuela. I graduated with a Bachelor of Elementary Education at the University in Caracas. I was a primary school teacher (1-6) for 3 years and then I was teaching English and Spanish at the middle school for 7 years in my country.
Currently, I live in Waukesha with my husband, Leybant and my two daughters (Andrea and AnaCorina). I enjoy cooking, watching movies, eating out and spending time with the family. I like to work at La Casa Charter School because you feel a team work environment, there is an opportunity to grow professionally, and families and staff feel at home like a big family. I love my work, I love teaching, I love to work at La Casa.
My name is Sarah Daniels, and I have been working with La Casa de Esperanza Charter School for the last three years. I have a bachelor’s degree in education that I received from Alverno College in2008. Since then I have participated in many workshops, online seminars and teacher collaboration meetings to stay up to date on new practices. Overall, I have 11 years teaching early elementary school students in grades K4-1st grade. When I’m not searching Pinterest for fun, new ideas for the classroom I love to spend time with my family, friends and pets. We love to be outside hiking, playing sports and traveling. I love the support I receive from parents at the Charter School and how we can work together as team to make sure each child is getting what they need. What I love about La Casa as a whole is the family environment and how La Casa focuses on the well-being of the entire family.

1st Grade Teacher
Hello, I'm Kimberly Ipsa, and this is my second year at La Casa de Esperanza Charter School as a K5 teacher! I've received my Associates in Liberal Arts degree at Bethany Lutheran College in Mankato, MN. At the time of my graduation, it was only a two year college, so I finished my education at Lakeland College(now University) based out of Plymouth, WI. I've been blessed to be able to teach scholars for 13 years in first and second grade. I look forward to helping all of my kindergartners grow and reach their full potential, academically and socially. I am from Mukwonago, WI, and married with four children ages, 8, 11, 13 and 15. I enjoy spending time with family and friends camping and at the lake. I also tutor Chinese students in English online during weekend.
I love that La Casa is there to help every student reach their full potential. Sometimes that means going beyond supporting just the student. La Casa has many programs and activities that help parents. These programs include weatherization, housing, tax help, school uniform help, transportation to and from school, and connecting parents to other programs that best help them. This support benefits whole families and ultimately gives students the support they need to be their best in the classroom.
1st Grade Teacher
Hi! My name is Kari Scheifen and I have been a K4 teacher at La Casa for the past two years. I’ve worked in early childhood education for the past 18 years, in various positions teaching children, birth to 5 years old. Before coming to La Casa, I worked in an early childhood center for 14 years, then as a K4 teacher in an urban private school for two years. I earned my bachelor’s degree in education from Lakeland college in 2014. I currently hold a Wisconsin State license to teach Pre-k through 6th grade. Early childhood is truly my passion and I look forward to a new adventure every day. When I am not teaching, I enjoy spending time with my husband and two daughters. As a family, we like to go to the movies, play games and go on spontaneous road trips. A few of my favorite activities are reading, shopping and crafting. What I love about La Casa is having the opportunity to work for an organization that provides service to my hometown community of Waukesha.
2nd Grade Teacher
Hi, my name is Jazmin Genao and this is my first year working at La Casa de Esperanza Charter School. I have a bachelor’s degree in Psychology, and I completed the CESA #1 teacher certification program. This is going to be my 5th year as a teacher. I enjoy project-based learning as it gives students hands-on opportunities in the classroom and it keeps them engaged in learning. I am very excited to become a member of the family at La Casa de Esperanza and I am looking forward to getting to know the families and students to best serve their needs.
When I am not teaching, I enjoy spending time with my family engaged in activities like going to the park and the movies. I love singing karaoke with my daughter Paulette and playing the guitar.
3rd Grade Teacher
My name is Justine Alswager and I am the third-grade teacher at La Casa de Esperanza Charter School. I have been with La Casa since March of 2017. At that time, I took over teaching K5 while the teacher was on maternity leave. The next year I started the school year with K4. I have been working with preschool-aged children since 2002 when I began as a teaching assistant at my daughter’s Head Start program. I went to school to become a teacher and I have been a teacher since 2011. I have my bachelor’s degree from Lakeland College along with a teaching license through the Wisconsin Department of Education for grades Pre-K through 6th grade. I also hold a Level 15 with The Registry, an organization which verifies that individuals exceed entry-level requirements for childcare as established by The Wisconsin Department of Children and Families. I live in East Troy with my three children, cat, and dog. My daughter is 21 and my sons are 13 and 11. In my personal time I read, and I like learning about and discussing current events. I also love anything in the arts including music, theater, literature, movies, and dance. When the weather is nice, I spend a lot of time outdoors at the beach relaxing or hiking in the woods.
I love how La Casa de Esperanza Charter School serves a close-knit community. Many of the families who have students attending La Casa Esperanza have been attending and supporting the organization for many years, even before the Charter School opened its doors. I also love how the school has a small and family-like atmosphere where the staff and students know each other by name.
