Mildred Jane Posega Sivavec

  • On September 11, 2020

Mildred Jane Posega Sivavec, 88, of Canonsburg peacefully passed away Wednesday evening with her sons Larry and Donald and daughter Carol Bookmiller by her side.  She was preceded in death by her husband Anthony Robert Sivavec in 2007. 

Mildred often spoke fondly of her childhood in Strabane spent with her loving parents, the late Paul and Theresa Posega and her two brothers, Robert (Sherri) and the late Paul  Jr.(the late Barbara) and her extended family, the Martincics.  Mildred moved to North Strabane after she was married  to Tony in St. Patrick’s Church in 1953.  

Mildred was a graduate of Canonsburg High School, Class of ‘49 and Robert Morris Business College.  During her career she was employed as a secretary by the Canon-McMillan School District and then worked as a medical assistant for Doctors Anthony S. Galletta, David C. Mittell, and William H. Kittrell.  

Mildred was a member of St. Patrick’s Church in Canonsburg, SNPJ Lodge 138 of Strabane, and the local and national Association of Medical Assistants.  She was a volunteer at Canonsburg Hospital and for the Neurofibromatosis Clinic Association.

Mildred was the doting grandmother of Kelly Schmidt (Kevin) and the late Amy Bookmiller.  Recently Mildred became the great-grandmother of beloved Amber Mae.  Mildred also enjoyed being Aunt Mildred to her twenty accomplished nephews and nieces and their families.  She was the sister-in-law of Bernard (Dorothy) Sivavec, the late Henry (Cathy) Sivavec and the late Mary (the late Anton) Leban. She cherished her family and her friendships with childhood companions, neighbors, and medical office friends.  

Pittsburgh Cremation & Funeral Care on 3287 Washington Road, McMurray, PA will host a viewing on Monday, September 14 from 1PM-3PM and from 5PM-8PM. A private funeral will be held on Tuesday.

My sincerely condolences to Carol Ann, Larry, and Donald and to your extended family. Your mother was always inspiring as a modern, loving and caring mother and ahead of her time in having a career that helped fulfill her life. She was a beautiful as well as a very private person, so I can't say that I knew her well. I'm sad that I have had so little opportunity to see you all in the almost 5 yrs since my mom's funeral. I hope you have only good memories of your mother as I do.
