  • "I am so grateful I met you!"

    I've been seeing Dr Grisales for 11 years now, and I have to say that he is the kindest, most compassionate and caring doctor I've ever met. I never feel rushed or hurried with him. He always takes appropriate amount of time to make sure he has helped me with everything that I need and his staff are also super friendly and helpful as well. I'm always recommending his office to my friends, family and even strangers because I truly believe in him as a physician

  • "Outstanding, superb, compassionate pain management physician"

    Outstanding, superb, compassionate pain management physician and Dr. Harold and staff. Gives patients all the time they need. Just does NOT write pain medications. Offers options and if he cannot treat you, he refers you to the very best physicians or professionals in our area or beyond. His patients are his No. 1 priority! Tom and I have referred many friends to him. The only reason some couldn't go would be their insurance. I can write a best selling book about Dr. Grisales. Many years ago in the hospital, he saved Tom's life, in Tom's opinion. That is why we are with him...

    My mom broke her back in the Army and has suffered in more pain than I can imagine for 35 years. Nothing worked. Dr. G. has given her her life back!! He is an amazing doctor. He and the office staff are friendly and always take the time to be personable, it's not just about business with them.
