Started procedure before I was sedated. When I woke up at home I had a bruise on my jaw and could hardly open my mouth. No explanation was given for why my face was injured during a routine colonoscopy.

Very nice and asked several questions before the procedure. I felt like he wanted to be sure and look at anything that was necessary.

Outstanding gastroenterologist
Dr. Tomal is an excellent gastroenterologist — extremely knowledgeable, thorough, and genuinely caring. He takes the time to explain things clearly, answers questions without rushing, and makes you feel confident in the treatment plan. He’s proactive, up-clear, and truly invested in helping his patients feel better. I’m very grateful to be under his care and would highly recommend him to anyone needing GI care.
