    Dr. Lee is very thorough. Very good at explaining what is happening and why procedures are recommended. Colonoscopy screening saves lives.

    Lee because he was in network, and even though he had some poor reviews, all the other gastroenterologist had negative reviews also.

I'm scheduled for a colonoscopy- I was told that the soonest they could get me in for the procedure is August 21, 2025 I have called to ask for something sooner but his scheduler said nothing sooner and if pain persists go to the hospital. Honestly this was very unsettling. I had blood work done she also stated that the PA signed off on it so if something was alarming I would have gotten a phone call- this is neither reassurance. Initially to get in with the doctor I called for 5 days looking for a cancellation as recommended by the staff to be seen sooner (no success) some of these reviews are scary . Document Everything. I was also granted a referral for the Doctor but I seen the PA . I'm not sure what the protocol is.

I was told they could not do the procedure and would have to contact the heart doctor. Six months, never contacted the doctor but, they billed 265 dollars to take my phone call. What a scam!

I am fully aware of anxiety/ panic attacks and this wasn't it. I had severe chest pains, high blood pressure, severe headache, sweating and started vomiting so finally decided it was time to go once I started vomiting. Mind you I was about 6-7 weeks post op a total hysterectomy. I went with no bra because the chest pain was so intense and my abdomen was still so sore from surgery. The man who did my ekg asked if I'm comfortable just walking around with no bra ... I was pretty shocked it being the ER but told him yes I can care less because my situation. I barley could walk due to the dizziness and vision problems I was having aside from everything else. But no biggie I brushed it off. Then the man who did my IV tells me, can you walk?! As I was in a wheelchair. I was like no dude I'm so dizzy and sore from my surgery. Made me feel like such an inconvenience and very embarrassed. Long story short they chummed it up to be chest pain and anxiety. I never even mentioned it had anxiety so that was weird. I expressed how bad my heart and chest was feeling and the ER doctor basically said I needed to follow up with an endocrinologist and there was nothing they could do aside from the meds they gave me. I was in complete disbelief. Went home feeling horrible but followed up with my primary and now I am seeing an endocrinologist who is sending me to Loma Linda hospital. You really have to advocate for yourself. It's so sad how they make you feel and brush off your symptoms. Especially when you're at your absolute worst. Even on my forms you can tell they tread lightly labeling it chest pain but still slightly mentioned my pheochromocytoma. Also, would have been nice for them to mention I had kidney stones but the emergency room doesn't feel that is a serious issue so I am aware they wont mention the findings, but its listed as some of the most painful heath issues. The wait was fine. Expected from an ER. If I end up here again I truly pray they do better and hope people get the care and compassion they need. I left two stars because my visit was in March. Today I visited the main hospital to retrieve my scans on a disk to give to the endocrinologist for the tumor and the gentleman who was volunteering in a wheelchair was amazing helping me navigate the hospital. The woman in medical records was also so very sweet and kind.

    I can honestly say I still couldn't be happier with the care I receive here…read more I recommend Dr. Trebilcock to people every chance I get--often on the spot. There is simply no comparison to the level of thoroughness, personalized attention, and natural, root-cause approach you receive here. It's something I've never experienced in traditional Western medicine. The staff at Integrative Health Institutes deserves just as much praise. They're friendly, knowledgeable, and communicate clearly. I'm always greeted with a smile, and they're genuinely helpful and supportive. If you're looking for a thoughtful, natural way to support your body through the aging process--and want real, quality time spent on your health rather than being rushed or overmedicated--I cannot recommend this practice enough.
