    It's always a pleasure to meet with Dr. Loscalzo. He is the quintessential doctor. I'm normally averse to doctor visits but I move with intention for my visits wit Dr. Loscalzo.

    Dr. Loscalzo is a very caring doctor and one that I look forward to seeing every 3 months. I have been going to this practice, before it was taken over by CHS, 35 years. Always great!

    Dr Loscalzo is very professional, kind and considerate to what his patients (I) experience. He listens and answers any/all questions, whether asked by me or who is accompanying me to my appointment(s). Recently, another provider reached out to Dr Loscalzo regarding my recent scans, wanting to perform a procedure "I can do." Dr Loscalzo shared this with me and as I sat there fearful he was going to suggest the same, he pleasantly said he told the provider, this is not in my patients best interest at this time. I am ever grateful, that he looks at the full picture and has my health and longevity as a priority.
