"Today I will tell you about my teacher who I love the most. Specially, she also is my mom." It is the opening part of my essay. We are practicing writing the topic "Describe a teacher you are impressed by most". 
Anyway, from my point of view,  the word "Specially"  in the sentence above is not really natural. 
Do you think so? If so, could you please help me to find a better word to replace "Specially"?
Thank you so much.
