Important Changes to Patient Communication

NEA is introducing Endobot, Elvis, and the Healow Patient Portal as our primary communication resources for routine patient communication and service requests.

What You Need to Know

  • Live-agent support will not be routinely available.
  • Patients are expected to utilize Endobot, Elvis, or the Healow Patient Portal for routine communication and service requests.
  • Routine walk-in requests requiring staff assistance must first be submitted through NEA’s approved communication resources.

🔒 Identity Verification Is Required

For your privacy and security, NEA cannot provide assistance until your identity has been successfully verified.

Identity verification is required when using Endobot, Elvis, and the Healow Patient Portal.

Please review the attached flyer to learn how these communication tools work and how they can help you receive faster service.

We’ve listened to your feedback. These enhancements are designed to reduce delays, improve access, and make it easier to receive the assistance you need while allowing our physicians and staff to remain focused on delivering exceptional patient care.

Please join us in welcoming Dr. Surani to the practice.

“Dr. Guerrero is wonderful! He is very understanding and works with you to get in the best health. He listens and is genuinely caring of his patients concerns.”
“Dr Khowaja and his staff are amazing!!! I was able to make an appointment very quickly without inconvenience thanks to the help of the front office. Autumn specifically assisted with my insurance, making sure my authorization was valid and I have no issues with my appointment. Since becoming a patient of this practice, my health has changed for the better! The staff is so sweet and helpful and most importantly patient with you. I will recommend this clinic to anyone in search of an endocrinologist!”
“My doctor, Dr. Najera, is very knowledgeable and explained everything to me in layman’s terms. I learned so much from him. I also must give a shout out to Ayssa, who stays on track and follows up on any issues I have needed help with. She is very smart, responsible and respectful. Thank you NE Endocrinology!”
“The practice has advanced since moving and experience has improved with new offerings. Director was helpful in explaining new services and helping with the updated portal.”
“The office was very clean and modernly decorated. The staff were professional and courteous. The doctor took time to explain and answer many of my questions. In addition, they appear to be up to date on the most current medications to aggressively manage diabetes and the complications that come with it. If you’re looking to get help with type 2 diabetes, I highly recommend these folks.”
“Excellent service!!! The medical staff was super nice and Dr. Martha was incredibly accurate and knowledgeable, she gave sharp and detailed information, I highly recommend her!!!”
“Responsive staff members, great online portal. Convenient location and I’ve been seeing Dr Khowaja for the past 2 years and my experience with him has been outstanding.”

The best endocrinologist

“Dr Guerrero is awesome! He explains everything well, even draws it out! He’s sweet and very caring. He takes his time explaining the labs and he always answers all my questions without feeling rushed. He’s knowledgeable in his field of study. He has given me a better understanding of my thyroid disease. I highly recommend him.”
“This is the most efficient, timely, well run, best staffed medical office I have ever been seen at. I’m in and out in 30min, every time. Dr Najera is an incredible doctor I absolutely love him and with his help I’ve lost over a hundred pounds in a year and a half, which has been life changing for me. The staff is so friendly my phone calls are always answered or returned promptly. Other practices it can be like pulling teeth to get prescriptions sent in or refilled but at Northeast Endocrinology I get my medication questions answered and refills called in the same day I inquire about it. I can’t overstate how impressed I am with this establishment and Dr. Najera.”
“I normally do not take the time to give a review but I will for Dr. Guerrero because he does take the time to listen and go over anything that is bothering you. So, if you are looking for a caring, well mannered, informative and 5 Star Personality, make an appointment with Dr. Guerrero. He most likely will give you “homework” but you’ll be better for it. Thanks,”

“Front office staff are extremely pleasant and always friendly with a smile on their faces.”

“I have been to many different medical offices and this is by far the best. Dr. Guerrero and his staff are truly a step up!”
“Dr. Najera is very easy going and down to earth. He explains things very well! He also also listened and answered any question I had! Happy to be a new pt here!”
“Being a type 1 diabetic with thyroid issues I have seen many endocrinologists in the San Antonio area throughout my years and Dr Guerrero is by far the absolute best. He takes time to go over any and all questions without feeling rushed or judged. He is up to date and knows how to use, fine tune & tweak all the updated diabetic technology & tools so I can use it to my advantage. On top of this, his staff is exceptionally nice and caring. I am thrilled to have finally found a doctor who can care for a disease I have revolved my life around and is there to really help me manage it and be my absolute best. I would recommend Dr Guerrero to anyone in need of an endocrinologist.”
“Dr. Bilbatua and the NE Endocrinology office in San Antonio have been exceptional care givers! Collaborating with Dr. Bilbatua on enhancing my diabetes management has been truly rewarding, and I deeply appreciate her attentive approach. The office staff is consistently friendly and incredibly accommodating. I look forward to continuing as a patient for the long term.”
“Dr. Ameer Ali Khowaja has been wonderful! He has gone above and beyond in managing my resolving subacute thyroiditis. On several occasions, he diligently followed up my laboratory test results and adjusted my levothyroxine dosage accordingly. He answered all of my questions and allayed my fear of going off the levothyroxine entirely. He is very dedicated and caring!”

Best Endocrinologists in South Texas by Far

“There are not enough words to describe the care I had been provided from Dr Omar Najera since 2016. He had under control my Graves’s disease, diabetes and other health issues that have been threatening my life for decades. With his knowledge, professionalism, compassion. dedication, persistent work with pharmaceutical companies, battling health insurance companies to provided me with the right medication every single month for years. His compassion and dedication is not seen in many physician. He is on top of advance and new treatments to provide the best care available for his patients. His attention of every detail while communicating with patients is second to none. His humility, simple way to explain complex medical approaches make him an over the top physician. His manners speaks of how respectful he always treat his patients. My experience as his patients pass way far my expectations. Dr. Najera is the doctor I’m lucky to have. For that and many more…I’m eternally grateful.”
