Kali’s constant battle with Crohn’s disease was jeopardizing every aspect of her life. Luckily, with Dr. Chudzinski’s surgical intervention, Kali is able to live a normal, healthy life once more.


My experience with Dr. Chudzinski and his team was nothing short of incredible. I would not wish Crohn’s Disease on anyone, but if you have it and require surgery, I highly recommend him. He is the most caring and compassionate doctor I’ve met. He eased every worry I had and had me into surgery 2 days after my appointment with him! I have battled Crohn’s for 7 years, and only a week out of surgery I was happier and healthier than ever.

Picking a surgeon is hard work…how do you pick someone to put your life in their hands? Dr. Chudzinski earned my respect after a recommendation from a friend and an initial consultation. [I appreciated] his approach to talking about a problem and how he would address the problem. Right before my surgery he had been pouring over my last CT scan and he brought something to my attention and said he wanted to address it my surgery.

I just wanted to take a moment to compliment Dr. Allen Chudzinski and his team.

He always takes the time to explain things to us and treats us with so much respect. I have dealt with many doctors as a nurse and as a patient and he has the most wonderful bedside manner. He really listens to the patients and their families and always gives them his full and undivided attention. He is always calling us his team members and says that he appreciates the care we provide for his patients. He is always approachable and loves to teach us so we can become better nurses. He is always kind and courteous even in the worst of situations. He calls us by our names and always asks how we are doing and genuinely cares about our response.

He even noticed that I was having a rough day and brought me coffee when he came to round on the floor, it meant so much to me.

Having him [as a] apart of the FHT team really makes us better. I always am excited when I get to care for one of his patients because that means I get to interact with him and his team.

Dr. Stylienos Tsintzilonis, his fellow, is also so wonderful to work with. He always has a smile on his face and is very attentive with the nurses and patients. He appreciates our input when related to their patients. He enjoys teaching us about the procedures they perform so we can better understand and care for the patients. One weekend when he was covering he noticed how hectic we were and he bought us all ice cream for a pick me up.

Deowattie John, ARNP is also a joy to work with. She always answers our questions in a timely manner and patients always say wonderful things about her. She always makes the time to help us and address any of our concerns regardless of how menial they may seem.

Of all the facilities I have worked at I have never come across a team so caring and compassionate. They are all so thoughtful and I feel so blessed to work with them.

– Nurse, 4 South Unit, Florida Hospital Tampa


My words say thank you for all of your professional care and also for the sincere caring for me as your patient. Thank you more than words can say! I am blessed-and my heart felt appreciation for your efforts will be with me always.

– Patient JM


So you just found out they want to take out a chunk of your colon and you’re terrified? I know I was when I got that news. Let me tell you about my experience.

I had a colonoscopy and a very large polyp was found. My gastroenterologist told me he was referring me to a surgeon who would remove the polyp. I met with the surgeon who informed me he would be removing the polyp along with 1/3 of my colon. That was the first I heard about that. He tried to push me to sign the papers that day and have the surgery the next day. I was crying in his office, out to the car and an hour afterwards on the phone with my sister who finally got me to calm down. All weekend I was on the computer to find everything and anything I could about the procedure. I had a follow up with the gastroenterologist the next week and asked for a referral for a second opinion, he was not anxious to give it. I felt bullied to make the choices I wasn’t ready to make. I insisted on a referral and he referred me to Dr. Harris.

I met with Dr. Harris and through him Dr. Chudzinski. Everyone in the practice understood my fear, that I had time to come to terms with what was going to happen, and time to get things in place prior to surgery and helped me feel comfortable with the decision. I never left their office without a smile on my face. I believe your confidence in your doctors has a direct effect on your recovery. I had the utmost confidence in everyone with this group.

Six weeks before my 70th birthday I went in for the surgery. Everything went exactly as I had been told to expect it. When I was released to go home, worry wart that I am, I expected to need help for weeks. Instead other than being afraid to get in the shower unless someone was home; I really was able to take care of myself.

My biggest fear had been I would not be able to ever go back to work. I work with kids, they give me purpose, and I love my job. It is now eight weeks since the surgery: I am back to my normal summer routine and in August will be back working with “my” kids”. My fears were groundless.
Suggestions: if you, like me, are frightened; take a walk, try yoga, anything that helps you calm down, call someone and let them know you need to unload, lean on family and friends.

Remember you are working with professionals who want the best for you.
If you have no family or friends nearby let the doctor’s staff know and they may have ideas for support.

Dear Dr. Chudzinski,
It has been one year since you did my colectomy, and I wanted to thank you so much and tell you how much you are appreciated. May God bless your hands always as you continue to treat those that need you.

– SB and MB


I don’t really know what to say except thank you for taking care of me when I first needed help. I feel great.

God Bless you all,

Dr. Chudzinski,

I couldn’t let today pass without letting you know how grateful I am for everything you’ve done for me. Today makes one year since my surgery and I have never felt better! I had my yearly colonoscopy last week, and I woke up from the procedure to Dr. Sanjeevi telling me there is no active Chrons in my body! I had never heard those words before. I have had the healthiest, most memorable year of my life and I’m on the least amount of medicine ever. You are truly amazing! Your care and expertise are one in a million!
