About us

Our school

Our school and our philosophy: Cossata Summers’ philosophy is best described by the famous old adage, “A sound mind in a sound body.” We are striving to achieve our goal through well-organized classrooms, active lifestyles during numerous summer trips, and a balanced diet based on the local Mediterranean cuisine.

Our small class sizes of 18 students or less ensure that everyone has the support they need to succeed.

Our students are academically involved, display good ethical values, and have a willingness to collaborate with their peers.

Our Ontario certified teachers are passionate about their subject area. They all have 3+ years of experience, and are currently working in the Ontario public school system.

Our trips are carefully spread between teaching days, providing the necessary mental and physical breaks to students. Fresh, local fruit is supplied twice a day on teaching days.

Student safety is our priority. Our students are supervised at all times. The ratio of students to supervisors is 9:1.

At Cossara, we motivate students to value their education and develop a positive attitude toward learning. Through each of the courses we offer, we’re committed to helping every student reach his or her potential and achieve a successful outcome from their school experience with us. Through a variety of cultural experiences, we help students develop a broader perspective on education, travel, and life.

Our principal

Valeria Daskalov is the owner and principal of Cossara Summers Education Centre. She graduated mathematics at Sofia University, the oldest university in her native Bulgaria that offers the most comprehensive mathematics program in the country.

After immigrating to Canada, Valeria became a high school math teacher and has been teaching in the GTA for over 20 years.

Valeria and her husband are avid travellers, and share this passion with their two grown children.

Valeria believes in the importance of education and the enormous impact of travelling on young people. This belief led her to create a program that offers the right balance between an academically strong education, and inspired travel.

Who is Cossara?

Cossara, also called Theodora Cossara, was the eldest daughter of Bulgarian Tsar Samuel, with much of her life entwined in legend. In 1010, after her father’s victory over Duklja, Cossara, known for her kind heart, asked to visit the prisoners. She was captivated by Prince Jovan Vladimir, known for his wisdom and humility. Falling in love, she persuaded her father to arrange their marriage, and Duklja was restored to her new husband. After Tsar Samuel’s death, Cossara’s cousin tragically killed both her husband and brother. Cossara and Vladimir had a daughter who later married the prince of Zeta, now part of Serbia.
