Since I cannot reply to the blatant dismissal of my statement- I submitted my survey anonymously and therefore I am writing in my alt email account which I use for chewy orders for my cats and dogs. Address your staff not me. The 2 stars go to the dynamic of the OR nurse and her team. They called her mom, which is sweet. I wish I could give more than 2 stars for 2/5 of the nurses. The surgeon can only do so much without a useful team as a whole. Sorry for the impending rant. Honestly, I beg you to avoid this place. The intake nurse was great at first but then she had to turn around and yell at the rest of the staff for mishandling charts. "Too many hands on the charts" she said. They got the wrong side of my body, the wrong appendage and wrong anesthetics for the procedure as I am about to enter. Not only did they get it wrong but it remained incorrect when I got stitches removed at a different location 9 days later. The intake nurse's reaction was somewhat forgivable but not in front of the recovery area patients, post-surgery. The communication is awful and the staff is hit or miss. One is nice, one is cold one is sweet and listens the other might just blow you off... Terribly inconsistent... but that's not even the worst part! The recovery room nurse, what a callous person - Kelly I think her name was. If it was not you, sorry to blow up your name... but people have to know. My partner and I were there and the recovery nurse was very rushed. She neglected to mention the possibility of constipation. Even if she did it was grazed over. She was really rude in affect to my partner who was asking clarifying questions because I JUST GOT OUT OF SURGERY. Do not talk to us like idiots, do not ignore our questions, and do not offer me juice and cookies and send me out the door. I had local anesthetic which was BOTCHED - nerve block lasted a little longer than expected and I had to go to ER twice in less than a week for resulting issues - vasovagal syncope aka fainting and dizzy spells due to blood pressure drops, mostly due to the pain. This interrupted my day to day life and work. They assured me I would be back to normal by Monday, since the surgery was Friday. I went to the ER at midnight the night of the surgery and again mid day at work the following Thursday (6 days after). And yes you can blame me as an individual patient but prior to this surgery I was decently fine. I have decent cardio and walked every day. After that I had to take a break from my routines including diet and exercise. 2 weeks after the surgery and I made it okay but even up until today any stress or mild discomfort felt amplified. Now I have to follow up with my GP twice and going to get my heart checked from the ER visits. I would not recommend this place if you care for your long lasting health. They will push you out the door, even with good insurance. I sure lit them up in the survey; I did not hold back and neither should you. Do not hold back. They need to swap out the incompetent people here.

Excellent place to go for something you don't really want to do, lol. But that's what makes them so great! This was my first time and I was scared and nervous. They made my experience so easy and pleasant. Dr. Smith was so nice and made me feel at ease, as did Heather and all of the staff. Everyone I dealt with throughout the entire process was friendly, helpful, and treated me with kindness and respect. Everything from scheduling to the procedure itself was handled well and explained to me in detail.
