Theresa Wiedeck

May 14, 1983May 1, 2020

Theresa J. Wiedeck of Unadilla went into the Lord’s loving arms after a long illness on Friday, May 1, 2020 and has been reunited with her beloved father John Raymond Wiedeck, whom she missed dearly. Theresa was born in Oneonta on May 14, 1983 to her adoring parents John and Sharon Wiedeck of Wells Bridge, where she was raised.

She graduated from Unatego High School in 2001 and SUNY Cortland in 2005. Professionally, Theresa spent her years in social work. For those who knew Theresa, and there are many, as a kind, compassionate, selfless soul who valued family, friends, faith, education, and always lending a helping hand. Theresa loved to bring joy to others in any way possible with her quick wit and sass. Much like her father, many will remember her for her laugh and as her mother taught her, compassion for others.

Far too soon she leaves behind her best friend and loving life partner of almost 20 years, Curtis F. Underwood. Her affectionate mother, Sharon Wiedeck, and wonderful sisters Moriah Ross and Suzannah Wiedeck. Her nieces and nephews who were the joys of her life: Pehlyn, Lenohn, Mariama, Ethan, and Arianna. Her cousin and close friend, Jerianna Brown, and her soon-to-be baby boy. As well as other aunts, uncles and cousins. Theresa adored her life partner’s parents Scott and Charyll Underwood, and sisters Emily and Dorothy Underwood. As well as many, many dear friends and colleagues who she loved like family.

There will be no viewing or funeral at her request. Instead a Celebration of Life for family and friends will be held in honor of Theresa at a later date when it is safe for us all to be together and remember all the joy she brought to those she touched.

Donations in Theresa’s memory can be made to The Catskill Center for Independence, 6104 State Highway 23, Oneonta, NY 13820. Her family will have oversight on how those funds are spent to ensure it is what Theresa would approve.

An infectious laugh and sweet smile were the first to arrive on the scene when I met Theresa at Opportunities for Otsego. Her enthusiasm and warm welcome as I joined the team at Building Healthy Families will not be forgotten. She has touched so many lives, lightened so many burdens, and warmed so many hearts. God Bless you, Dear Theresa. Enjoy your sweet reward!

Sharon and family,
So sorry to hear of Theresa's passing. My heart is heavy for you. I met Theresa while both of us were volunteering at the local free clinic. I found her to be such a happy(and funny)young lady, just like you and a pleasure to be around. (You and I worked together on 2 North years ago) My Prayers and sympathy are with you.

A beautiful soul gone too early. I had the chance to work with Thersa when she would come to OSS. I met her thru Joanne Underwood. We would all have lunch together. She will be missed. Sending lots of hugs and prayers to love of her life and her family.

I had the great pleasure of working with Theresa twice. She was a very kind, caring person who truly cared about the individuals whom she helped in her work. She went out of her way to help others to have a better life. There are no words to describe what a loss her death is. There should be many more people like Theresa in this world. RIP, Theresa. It was my honor to have known and worked with you.

Quick wit and sass is exactly how I remember Theresa, along with her compassion for others! She always put a smile on my face in high school! I'm so sorry for your loss Curt and The Wiedeck Family!

A person could never describe Theresa with one word. It wouldn't do justice to that little dynamo I first met at St. Mary's School. Never, ever without a smile. Always being so helpful. The spirit of a million wild horses. You are so precious. Rest in peace Theresa. The angels in heaven have met their match for most gracious. Prayers Sharon and family.

Curtis, I'm so sorry for your loss. Our exchange student, Inken, became friends with Theresa when she was with us and would spend time with her in Wells Bridge. My thoughts and prayer are with you and yours.

I always remember Theresa's first birthday. Sharon gave her a cake and we all stood back and watched the chocolate disappear. We weren't sure how much she actually ate but she was wearing quite a bit but the smile on her face was amazing. Theresa also was the one I could always to find out the truth of whatever drama was going on in NY even if she was involved. Smart, Funny, Beautiful and Inspiring. My heart goes out to Curt and the Wiedeck Clan. Love You All Always!
