  1. I was an alumni of St. Dunstans in Millbrae. Sister Catherine St. John Byrne was my teacher in 7th and 8th grade. She had a very huge positive influence on my life. I would like to be able to write her a letter of thanks, but I do not know how to send it to her. Is there a way I can do that? Please let me know.

    1. Hi,
      Thank you for your message.
      I have forwarded it to Sister Catherine St. John, including your email address.
      Hopefully she will be in contact.

  2. She was my 7th and 8th grade teacher as well and she is one of the most kind and giving people in my life. She was creative and wrote cheers for us, she'd have us dance to "Blow the wind down Oly blow the wind down"; she was so creative. I wish I I appreciated her as much back then!
    All the best to you Sister Kathryn Saint John!

    1. Hello Nancy! Thank you for sharing your appreciation of Sister's creativity with such a specific memory. I'll forward your message to her, along with your email, and I'm sure she'll be happy to know you were thinking of her.

      (for the Sisters)
