Great Lakes Sleep Medicine Institute

I've been reaching out to this place for MONTHS to be able to get new needed CPAP supplies. No response to calls, voicemails or texts. Will be checking out the far more competent professionals others have suggested and taking my business elsewhere.

This is, without exaggeration, the single worst medical facility I have ever dealt with. Great Lakes Sleep Medicine manages to combine breathtaking incompetence, indifference, and outright disrespect into one miserable package. From the moment you walk in, you realize that no one here cares about your health, your time, or even basic human decency. Appointments are treated like vague suggestions rather than commitments—expect to wait for hours past your scheduled time while staff shuffle papers, laugh loudly behind the desk, and pretend you don’t exist. When you finally see a doctor, don’t expect professionalism, compassion, or even the faintest sense that they’ve read your chart. They speak in rehearsed clichés, rush you through, and offer cookie-cutter “solutions” that don’t address your specific problems. The entire place reeks of a “bill insurance first, care later—if ever” mentality. Communication is an absolute disaster. Messages aren’t returned, test results are withheld for weeks, and if you try to follow up, you’ll be met with hostility or flat-out gaslighting—staff insisting they “already called you” when they very clearly did not. The front office is astonishingly rude, speaking to patients with the kind of disdain you’d expect if you had personally insulted them. Any attempt to advocate for yourself is met with eye rolls, sighs, and dismissive comments. The sleep studies themselves are a joke. Equipment is outdated, filthy, and questionably maintained. The “technicians” (I use that word loosely) seem utterly untrained, fumbling through hookups and then vanishing for hours, leaving you stuck in an uncomfortable room that feels more like a prison cell than a medical facility. Results, when you finally get them, are vague, contradictory, and suspiciously identical to what they give everyone else—almost as if they’re rubber-stamped to push CPAP machines instead of providing actual individualized care. This place is a black hole for time, money, and trust. They prey on vulnerable patients who are desperate for help, stringing them along while delivering nothing but stress and frustration. If you value your health, your sanity, or even the basic dignity of being treated like a human being, avoid Great Lakes Sleep Medicine at all costs. You will regret ever stepping foot inside this circus of incompetence.

This place is awful. I went in because I believed I had sleep apnea which was starting to effect my whole life, personally and professionally. I got my in-lab sleep study done, which was fine and it came back that I have it, really severely at that. I was brought in to go over the next steps, which would be a titration study and ultimately a CPAP machine. I was excited that this was finally getting taken care of. And then, nothing. I'd call up and they would just say they were working on it. a couple weeks later I'd call up again with the same response. This went on for months before I finally gave up and went to another place, who has been awesome. I went almost 8 months between diagnoses and treatment because of this place. I cannot in good faith recommend this place to anyone.

Dr. Stefadu is very kind and patient. He did a wonderful job explaining things simply so I could understand what was going on. Treatment has definitely improved my quality of life.

I was very skeptical at first but Dr. Stefadu was very knowledgeable and patient to me . My sleep improved a lot without any medications at all. Highly recommended professional. My husband is a truck driver who needed a sleep study to be done. After my great experience with the office a scheduled his appointment as well. Stuff members worked with our schedule and he was able to couplet all the testing needed on time without any days off. Thank you!
