Updates from Father Kusi

 2020 Changes in the Parish Office

Greetings to you all my beloved brothers and sisters. I hope you’re enjoying the beautiful Michigan outdoors and these glorious summer days. We have had a lot of graveside funeral services for immediate family only. It’s so sad, but that’s what we have to deal with at this challenging time. Many are dealing with loved ones who are ill and are now truly “homebound”! And to you all who are going through very difficult issues, please know that you’re not alone. You’re always in our thoughts and prayers. And by the way, I have been trying to call as many of you as possible, especially the seniors, many of your phone numbers have changed, some voicemails are full, some just keep ringing – no answer! I got sworn at in one of the phone calls because the parishioner’s number had changed. So please update your phone numbers with our parish office so we can keep in touch with you. To those of you who are young and healthy, remember we’re not out of the woods yet with this Coronavirus. So stay safe, wear your masks, and practice social distancing to show your love of neighbor.

I would like to let you all know that there are some changes in our Parish Office as we move forward to the new fiscal year. First, Alison Burch has asked to resign from her position as Business Manager. She has been the longest serving member of our staff. I’d like to take this opportunity, on our behalf, to thank her for the many years she has served our parish so faithfully, from a Religious Ed. Secretary to Bookkeeper to Office Manager to Business Manager. Alison, we thank you for your dedication, commitment, hard work and the many, many sacrifices that you and your family have offered in love of God, for your faith and your Church. As a Pastor, I will always be proud of you. I thank God that you as Business Manager and Shannah Havens as Finance Chair, were sent to us to help in the merging process of our two parish finance accounts. During this pandemic time, you have been influential in keeping our finances intact and applying for our PPP funds to keep us safe during this uncertain time. We wish you all the best in your future endeavors. Know that you are loved so much and please forgive us for any trespasses. You will be missed!

Secondly, to take on Alison’s job, she has been training Bonnie Sweet in her new role. Bonnie has served for many years as Secretary and Bookkeeper at Bunkerhill so she is learning fast and familiarizing herself with work she used to do before. We thank Alison for offering to help and guide Bonnie during this transition. And we thank Bonnie for stepping up to the plate.

Thirdly, since we’re moving our parish from Maintenance to Mission, we have to invest in personnel and tools for Evangelization. So I have asked Heather Dunivon to work full time as Evangelization and Outreach Coordinator. She will continue to run the Alpha program, Amazing Parish program, Divine Renovation Initiative, Evangelization Commission, Communication tools in social media and be part of our Senior Leadership Team.

The role of the Youth Minister Position has been offered to Nicole Retz and she will also be responsible for the Confirmation Prep. Program. Nicole has been a very faithful youth ministry volunteer for so many years. She has the heart and passion for teenagers. And now with their youngest son, Thomas, graduating she has got time to make a huge impact and have fun with our teenagers.

These are the changes for this year 2020. So when you have the chance please thank Alison Burch for her services to our parish. I’d like to ask for your prayers for all of the staff as we move forward from here. Thank you and God bless.  Father Kusi
