“We are so very lucky to have these amazing doctors in Plymouth! They have helped me many, many times. Dr. Casey and his staff are my go to peeps for many different issues. He really has gone that extra mile. I believe he does for all of his patients. The office manager where I work recommended him several years ago because she can’t say enough about Dr. Casey and Dr. Koren.”


kathy brown new hampshire snow bird and patient at speare general surgeryFor years, Kathy had been experiencing on and off pain. She describes it as cramping, and chalked it up to gas build up. She noticed the pain when she was at home resting or sitting, noting that when she got up and moved around she had no discomfort.

In 2014, Kathy found herself in the Emergency Department at Speare Memorial Hospital with severe abdominal pain. The CT, or CAT, scan ordered by Dr. Casey on that fateful day left no doubt about it . . . Kathy had a blockage in her colon as a result of scar tissue build up after two C-sections, a hysterectomy and gall bladder surgery. Click here to continue reading…


“Taking responsibility for my own health has always been a challenge. I was too busy, too tired, and had too much to do. A friend asked me to please pay attention to this fault and go get a colonoscopy. I had one several years ago at Speare, but was not an employee at the time.

I clocked out of work and saw Dr. Casey in his office. He was kind and listened. As I was discussing my family history I became aware that this was an important exam for me. My father died of colon cancer, my sister was diagnosed three years ago with stage 1, and my big brother had just lost his battle to renal cell cancer. The time was now.

I picked a date that was convenient for me. My prep was ready at the pharmacy. I left work at noon to prepare. I arrived promptly at 8:30 am the next day and was taken into my very own room. I was wheeled into the room where Dr. Casey sat at a console which reminded me of the Starship Enterprise. We joked and I laughed. I woke up to my favorite things to drink and I was discharged. I had no recall of the test but was readily informed of the star quality of my colon!

How fortunate to have this resource right in our back yard. No long travel time, no inconveniencing family to take a long ride to Concord which would include a day off, and no side effects from the procedure at all. Please take the time to do the responsible thing. Have your colon checked. It could save your life.”
