Meet Our Home Care Team
Lisa Wiedemann MS, OTR -  Franchise Owner/President

Lisa Wiedemann MS, OTR, Franchise Owner/President

Lisa Wiedemann founded the Home Instead Senior Care office in Williamsville, NY in November of 2004. Lisa brings 30 years of experience working with geriatric population. She earned her Bachelor’s and Master’s Degrees in Occupational Therapy from D’Youville College. Her experience ranges from working in an acute medical rehab hospital in central California, to being employed as the only full time Occupational Therapist at a major home care company in downstate NY running two counties, to teaching at the college level for four years. She has been very active in local organizations, like the WNY Chapter of the Alzheimer’s Association serving on the Programs and Services committee as well as the Education committee since 2005. Furthermore, she served for 10 years with the Board of the Amherst Senior Transportation Services and was Vice President for 3 1/2 years looking for ways to improve transportation in her community. Lisa is also a member of Erie County Caregiver Coalition since 2005 and is an active member of WNY’s Network in Aging.

Lisa also knows firsthand what it is like navigating the healthcare system since her mother was diagnosed with Parkinson’s disease over 25 years ago. Her mother was a longtime client of Home Instead Senior Care and was the inspiration for starting the business. Her Mom raised seven children alone while working as a registered nurse at a local hospital but her mom's disability forced her to leave as well as give up her driving. Further, Lisa's only aunt was also a long term client of Home Instead suffering from Parkinson's Disease. Both Lisa's aunt and her mom passed within one month of each other in 2016.

Lisa loves being with and being able to work with her husband Eric. Their son, Carl who had grown up alongside the business, is pursuing his doctoral degree in Psychology at Stonybrook University.


Eric Wiedemann, PsyD, Franchise Owner/Chief Operating Officer

Eric joined Lisa full-time at Home Instead Senior Care in 2006. He earned a doctorate in clinical psychology in 1996 from the California School of Professional Psychology in Fresno, California specializing in cognitive behavioral therapy. Following that, he spent many years practicing psychology full-time in public service and in the private sector. Eric continues to maintain a part time consulting psychology practice. Eric is also a proud veteran of the United States Navy where he served four years active duty as an Intelligence Specialist.

In addition to his responsibilities at Home Instead, Eric is very active with the local chapter of the Alzheimer’s Association! He has served as their Board Chair from 2011 through 2014 attending and helping with many events & programs over the years along with the collaborative efforts that coincide with assisting in governing the strong local WNY chapter. Over the years, he helped at several of the local Walk to End Alzheimer’s throughout Western New York; from assisting at 4 local walks in the greater WNY area in 2014 to helping in the early hours in the morning setting up tables in the pouring rain. Eric also served on the board with the Character Council of WNY. And if that wasn’t enough, he also served many years in his local Catholic parish community on the Parish Council as Secretary.

Lisa and her husband Eric are proud to represent on a local level the caring and love that the Home Instead Senior Care model brings. The goal of our Williamsville office is to serve the unique needs of each of our clients as if they are our own family. Caring is what we do. It is what we love! We would love the opportunity to get to know you! Contact us today if you have questions or concerns about home care for your loved one and we'll help you work through the decision-making process.
