This is my repeat visit five years after my first. I had an excellent experience when I was there…read morelast time. And today's visit is nothing short of outstanding. What are some of the things that made the visit better. First of all, the preregistration and all the questions and forms that you fill out are done ahead of time online and on their phone app. When I got to the clinic, I scanned the QR code that was sent to me. Within minutes, an assistant placed a band with my name and number on my wrist and directed me to the second floor. After a very short wait, a nurse called my name, checked my wristband, and took me back to my room. Within a half hour, I was undressed, and the monitors placed IV started, and I was ready to head out to the procedure room. My doctor came into the room, asked me the usual doctor questions, and had me sign the consent form.

Had my scheduled colonoscopy procedure done yesterday at the Digestive Health Center. Due to my…read morefamilial history and prior personal results I am on the 3-5 year plan for colonoscopies. I've had about 6-7 prior colonoscopies using the monitored sedation method. All were relatively pleasant experiences including my two prior procedures also at this facility. Yesterday, a few minutes before I was wheeled into the room where the procedure was to be performed the physician checked in with me and explained that he would be using the "conscious sedation" method. I explained my trepidation with this form of sedation given past negative experiences I witnessed with my parents. The doctor stated that the conscious sedation would cause fewer issues after the procedure. I responded that I have never had any post-procedure issues with the monitored sedation. By his reaction, It was obvious that the decision had been made and that my input did not matter. I was wheeled in to the procedure room. What followed was the stuff of nightmares. Despite being dazed and unable to speak I was an unwilling (albeit mute) participant in the doctor's running commentary with the two nurses assisting him. I felt the insertion of the probe used for the procedure as well every push of the instrument as it proceeded further through the colon. To say that this was an uncomfortable experience would be an understatement. Adding to the unpleasantness is the fact that it felt downright humiliating. I am mostly troubled by the fact that I was given no input whatsoever in the form of sedation that was used. I am aware that there are medical considerations that factor in when a physician decides on how to sedate a patient. However, I informed the physician that I have had absolutely no adverse issues with the monitored sedation used during everyone of my other colonoscopies. The patient should be informed and have some input on what is being done during any medical intervention. The news of the sedation method to be used was presented to me at the last minute, almost as an afterthought. I believe that the ONLY times a doctor should unilaterally decide are: A) If the physician is paying for the procedure, or B) If it's their colon that is being explored. I strongly suspect that the physician's employer may be dictating the "conscious sedation" on it's practitioners. My doctor mentioned that prior to my afternoon appointment he had already done 11 procedures, and still had one more after mine. With "conscious sedation" there is no need for the recovery time usually associated with other sedation methods, so post-procedure patients can be ushered out the door a lot quicker. This would allow for one doctor to do many more procedures in a day thus increasing the clinic's profitability.

I was a patient for nearly two years and consistently experienced poor communication from this…read moreoffice. Getting test results often required repeated follow-ups, and appointment wait times were frequently excessive. My most recent visit was unacceptable. I came in for a follow-up after a serious hospital stay and was turned away because the office claimed they hadn't received a fax, despite it being sent the prior week. No real effort was made to locate it, and I was even refused when I offered to email the records myself. Dr. Dyer never spoke to me directly and instead made dismissive, disrespectful comments to staff within earshot. Given the length of time I was a patient and the circumstances, this was deeply unprofessional. I will not be returning and do not recommend this practice.

I've been calling her office for months, leaving messages. No return phone calls whatsoever. Then she refused to fill my medication again, even though in her own very words, this was the only medication that was left on the market, with the exception of Famotidine. She only works two days out the week Monday and Wednesday and I called leaving several message, begging and pleading for someone to call me back. Never received a return phone call for months.

Dr. Srihari Ramanujam is a highly qualified internal medicine specialist with a G.I. sub-specialty,…read moretrained at the Medical College of Wisconsin. He saved my life, when my routine colonoscopy revealed pre-cancerous sized polyps. In spite of reminders from my primary care physician and other medically trained relatives, I was procrastinating the process for lame but obvious reasons In an unfortunate coincidence I heard about two friends of friends who died suddenly and prematurely, younger than me (younger than me!) because of insidious colon cancers. Here, by the way, is the proper use of the word, as insidious means a hidden, dark, entrapment - a gradual, unnoticeable process that results in serious harm (not exactly a synonym for evil, it's an adjective that can modify the word evil). Dr. Ramanujam's bedside manner is excellent, which is an absolute requirement for gastroenterology, I think I mentioned, for obvious reasons. My "procedure" (what a euphemism) was at the 375 River Parkway location in Glendale, (not to be confused with Columbia St. Mary's clinic actually named "the Glendale Clinic," which is in Brown Deer!), where his clinic staff is remarkably tactful, disarming, considerate, polite, and obviously alert, attentive to detail, competent. Unlike too many uneducated medical staff, those younger than me respectfully referred to me as Dr. de Silva, rather than treating me like a child ("Mr. Rohan," how insulting that is!), you so need the little shreds of dignity when you're in a hospital gown reeling from the humiliating "colon prep" (uggh). Okay, so why give a man who saved my life four instead of five stars? Well, it's not exactly his fault, but he works for Columbia St. Mary's, who, if you can consider corporations to be people, is something of a rapacious money-grubber, belying the expensive advertising suggesting that patient care is their primary motivator. Way back when I was diagnosed with sleep apnea, the physician ordering the sleep study made herself my primary care physician on the paperwork (without my knowledge). Then, because my insurance pays for sleep studies, every year with her tacit approval the sleep study clinic hits me with phone calls, and letters trying to scare me into getting follow-up sleep studies. Although my insurance would pay, since there's a standing physician order, there is no medical reason for annual sleep studies once a CPAP has reduced the sleep apnea threat, it's an expensive procedure that does not need to be repeated regularly (unlike colonoscopies or eye exams). Then, before this procedure, I got a dozen (no exaggeration) phone calls from different people representing Columbia St. Mary's, but since their priority was checking on my insurance status (the wallet biopsy), important medical preparation instructions weren't prioritized, or missed entirely. If I followed the phoned in instructions for the colon prep (uggh), I would have been behind schedule, but instead I followed the instructions from the pharmacist and on the box itself. Written instructions actually sufficed, but on the phone one of them gave me the wrong clinic address (actually a bit understandable, as I was supposed to go to the clinic in Glendale, not the "Glendale Clinic," but why would you name the clinics this way?). The worst was a frightening series of calls from their outsourced "preregistration" "Service." Preregistration, not a word by the way. The day before, when I was already preoccupied with the "colon prep," (uggh), I got a very suspicious call from a highly inarticulate woman purporting to be working for "preregistration," (not Columbia St. Mary's) asking me the sorts of questions one would need for either identity theft or house burglary. You know how you know that the Nigerian Prince e-mail scam is a scam because the spelling and grammar is so weak? Same reason to suspect this caller. Although I cut that call off halfway, I was still so worried about what information I did give I didn't sleep at all the night before the procedure, though I wonder how well I would have slept given the "colon prep" (Uggh.). She was asking all sorts of information that the hospital should already have, without any reassuring reason. I think that's because there is no reassuring reason, they (the institutional "they") just have all sorts of redundant processes to insure patient ability to pay. I was about to use a metaphor (pay out of the nose) that would be inappropriate on two or more levels. Okay, so if you're over 50, get a colonoscopy. If you want the best, schedule it with Dr. Ramanujam. Be prepared for the Columbia St. Mary's shake down before your "procedure," it's as bad as the "colon prep," (uggh), but the the lead-up to the colonoscopy is the only bad part, the actual procedure in the clinic is not at all unpleasant because of the staff at the clinic.

Date of visit: September 11, 2025…read more I brought my friend here for a colonoscopy and while I wasn't the patient, it was an overall good experience for me as his transport and emergency contact. The staff were communicative and friendly, letting me know when he was ready and sharing updates along the way when he took extra time to come out of the twilight sleep. The office is a bit hard to find, tucked back in an office park where all of the buildings look the same and we found the patient pick up parking a lot easier than the drop off parking! The area for pick up can be a bit tight, so be mindful that you aren't blocking anyone's parking spot while you're waiting for your patient. The waiting room area seemed a bit tired and ready for a refresh, but otherwise it was a positive experience for me--which is probably easier to say since they weren't sticking anything inside me!
