Dr. Spencer's bedside manner and professionalism were wonderful, especially at a very sensitive moment of treatment. He knew how to comfort and assure me in an exceptional way. Despite a tough diagnosis, he made me feel confident that I would be treated this way possible and my best interest would be paramount.

Dr. Spencer was very clear about my treatment and asked me repeatedly if I had any questions or if he could answer any other concerns. Every staff member that came in identified themselves and told me what we would be doing that day. I've been very pleased with all the care I've received at the Delbert Day. Thank you.

I need referrals for both my insurance companies. The staff is amazing. I might have to cancel an appointment for a PET scan because TriCare wasn't informed of the order. I am still not approved with TriCare for radiation treatment. Thank you.

Everyone was absolutely amazing. This is a very scary time and everyone I saw was so nice and compassionate and explained things so well. I also have trouble breathing and to me the exam room was quite stuffy and could have used a bit more moving air. Besides that, I was very impressed and felt like everyone really cares.

Dr. Spencer listens to his patients. He is honest with his patients. I wish all the physicians at Phelps Health were more like him.

Helped me, thru their calm professional actions during the procedure, relax as best I could, perhaps making me a better patient. Felt very confident in Dr Chris and staff.
Feb 13, 2025
My first appointment went very well and very smoothly with the intake person being very clear in what information I had to provide for my appointment. My nurse was very thorough in taking my intake information and my family history, etc. She answered all of questions and if she couldn't, she instructed me to ask my doctor. Doctor Spencer was very informative about his plan for my treatment and answered all of questions I had that day. All caregivers were very compassionate and empathetic with what I was going through physically, emotionally, and mentally with my diagnosis! I left feeling informed, confident, less anxious about the treatment I was going to go through at the Cancer Center!
