Last updated: August 18, 2022

ThedaCare is thrilled to introduce our newest providers and learn what inspires them to improve the health and well-being of our patients and empower them to live their unique, best lives. 

Dr. Madhavi Reddy Cherukula, M.D. 

Internal Medicine, ThedaCare Physicians Senior Care Services  

“Caring for seniors is special because it allows me to meet people from all walks of life and build meaningful bonds. I thrive on treating complex medical problems and being involved in multidisciplinary environments that focus on quality and safety for our patients.” 

Gregg Brewer, LCSW, LMFT, LPC 

Social Worker, ThedaCare Behavioral Health 

“Working with patients of all ages, I assist individuals in crisis, treat post-traumatic stress disorders and help couples and families use their strengths to manage life’s challenges. My job is to offer support while helping patients expand how they think about and approach the issue at hand.” 

Ambir Dorn, A.P.R.N., M.S.N., BSN 

Family Medicine, ThedaCare Physicians-Appleton at Gateway Drive 

“Educating and guiding patients toward reliable information is important to me, so that they can make informed decisions for their overall plan of care. I have been extensively involved in implementing services to better serve our geriatric patients by offering them preventive care to help them feel safe at home.” 

Amber Greuel, LPC  

Licensed Professional Counselor, ThedaCare Behavioral Health-Menasha 

“The best part of my career in behavioral health has been watching people gain personal autonomy and make decisions that positively impact their lives. Empowering patients to set and reach their goals and creating an open, respectful, non-judgmental and safe space for them is important to me.” 

Dr. Robert Jackson, D.O. 

Orthopedic Surgeon, ThedaCare Orthopedic Care-Berlin 

“My philosophy has always been to treat patients as I would my family and friends. I believe that being an orthopedic surgeon is more than just knowing how to perform a procedure; it’s also about choosing the correct treatment plan for each patient.” 

John Kellner, P.A. 

PA-C, Emergency Medicine, ThedaCare Medical Center-Shawano 

“My favorite part of emergency care is putting all the pieces of the puzzle together to make sure the patient has been treated, not just on the medical side of things, but also in addressing their emotional needs. Communicating effectively with patients is important to me so that they are able to clearly understand their diagnosis and feel confident in their treatment plan.” 

Staci Radtke, A.P.N. 

APNP, Emergency Medicine, ThedaCare Medical Center-Shawano 

“Working as a team and communicating effectively in the emergency department help me provide exceptional care to all of my patients. I recognize that everyone has their own unique health care needs. I believe not only is it important to treat the illness or injury, but also to treat the whole person.” 

Dr. Amanda Sommerfeldt, M.D. 

Hospice and Palliative Care, ThedaCare Regional Cancer Center-Appleton 

“Working as a team and collaborating with patients to ensure the medical treatment plan aligns with their health care goals are what I like best about my job. Patients and families facing very serious or life-limiting illnesses may feel overwhelmed. I focus on helping them navigate the health care system, resource mobilization and support networks, and ensure their symptoms are well-managed.”
