Dr. Otero is very Great Doctor listens to you and very Compassionate. I would recommend him to all my friends and family.
Had my 1st colonoscopy by Dr Ramirez. She's very professional and performed the procedure excellent. The staff was very nice and helpful. I'm thankful for choosing Dr Ramirez.
The wait times here are just absurd. I'm sure Dr. Ramirez is great and all but after four appointments I've only met her nurse practitioner. If you have all day to burn she might be your gal but if you have a job you might want to find someone else.
Long waiting times are characteristic of Dr Bullock's. doesn't seem to matter when you arrive, be prepared to wait. Typical for me is 45-60 minutes. That's such a waste of my time. Totally takes the otherwise decent care I receive down to a grinding disdain for using Dr Bullock. Staff is irritating in its duty to ask same questions over & over again for the sake of their reports.
Dr Guerra has been my Gastroenterologist for over 15 years and as a retired RN I would place my care in his hands on any day. He has performed both Endoscopies and Colonoscopies on me multiple times and I have sustained no negative complication.He is very easy to talk to and explains things fully.
I have been a patient of Doctor Guerra's nearly 18 years. I first saw him as a favor for the Orthopedic Surgeon my mother worked for at the time. Prior to that he had a policy of not seeing patients under 18 years of age. I am forever grateful that he did as the Pediatric Gasteroenterologist had misdiagnosed Crohn's for 3 years. Dr. Guerra, I can say with all honesty, saved my life when he agreed to see me when I was only 16 years old.
Amazing doctor!!! Very patient, gives 100% to his patients to make you feel better. Amazing staff!!
Dr. Johnson was expert and confident. Staff was great in preparing me. Can I say I enjoyed a colonoscopy? It was not unpleasant!!
Went for an endoscopy, got their 30 min early for 10 min procedure at 1100. Did not get out until after 1500 hrs. Was told she was not in. Same story for other procedure visits with her.
Dr. Otero performed a colonoscopy on me. His staff was great, and the process was as easy as could be hoped for on a colonoscopy. He was there for me right when I woke up to give me the results and explain things to me. I was very happy with him and his team.
Good luck getting professional service, the labs they use obviously don't care what a patient is going through if they can't even do their job properly that the patient has to re-do test!! It took 7 days just for them to figure that out. PA Delgado could care less, promised to look into what the specimen reading meant , 7 days later no word from the PA. VERY UNPROFESSIONAL PRACTICE!!! I WOULD NOT RECOMMEND ANYONE TO COME HERE!
Top notch treatment throughout with all the staff and Dr. Johnson!
He is very thorough and attentive. He made me feel comfortable and explained everything clearly. I've used him for several years and would not consider going to anyone else.
Dr Guerra is nice and funny. The staff I saw that I can really speak highly of is the Nurse Practitioner, Karen Spencer. I would go back and request to be seen by her. Aside from that, staff is courteous and effective which makes things easier. Wait time can get long.
Phenomenal as always!! Dr Guerra and his staff are superb!! Super friendly!! I'm his patient for life!!
I have been with Dr. Ramos for over 15 years. Dr. Ramos has provided our family with excellent and professional care. We have been blessed with great doctors. Dr. Ramos is one of them.
Dr Otero was very condescending and rude. When I asked about the Mayor Clinic vs treatment he had available he replied why don't you hop on a plane and fly there. After this legit question he no longer seemed as if he wanted to help . He then offered a full refund as if he was admitting he no longer wanted help. We took the refund. Very unprofessional.
by Frederick M. on Apr 17th, 2016 Class act all the way. From answers to phone calls I'd made, from care I received once I arrived to once I left. These folks know what they're doing. I recommend them!
Dr. Franklin was very pleasant and caring. Good communication and the staff at SAGEC were excellent.
I went in for a routine colonoscopy, my first one. Dr. Guerra was very attentive, has a very positive and caring attitude, a great bedside manner and really listens. He explained what he saw in the photographs. When I went back for my follow-up, he explained the surgical options and what he would recommend and even wrote out notes for me to give to my surgeon. Not only is he a great doctor, but one of the nicest guys I ever met. I highly recommend him.
Dr Ramirez is very nice and listens and seems to really want to help you. Wait times for procedures though are ridiculously long. To wait more than 2.5 hrs after ur scheduled procedure to actually have it done is more than excessive! This part of the practice seriously needs some adjusting!!!
I have been a patient for a few years and he has always treated me with great respect. This provider listens and answers all your questions so you the patient understands what is the issue and what are the best courses of action to address the issues.
Poor bedside manner. Neglected to perform examination of any kind.
Very Professional office and staff. Will encourage my friends and family to consider.
