Services
IBS Diagnosis
Our comprehensive diagnostic process identifies root causes of irritable bowel syndrome through advanced laboratory testing and detailed patient history analysis. We utilize specialized labs to detect food sensitivities, bacterial imbalances, and other gastrointestinal abnormalities. This precision medicine approach enables targeted treatment plans that address underlying conditions rather than masking symptoms with temporary solutions.
Telemedicine Consultations
Remote medical consultations provide access to IBS specialists through secure video conferencing platforms. Patients receive the same thorough evaluation and personalized treatment planning as in-office visits, with follow-up support available nationwide and internationally. This eliminates travel barriers while maintaining continuity of care throughout the treatment process.
Food Sensitivity Testing
Specialized blood testing identifies immune responses to 96 common food antigens, helping patients understand dietary triggers for digestive symptoms. Our approach combines laboratory results with elimination diet protocols to create customized nutrition plans that reduce inflammation and improve gut health through evidence-based dietary modifications.
Personalized Diet Plans
Registered dietitians develop individualized meal plans based on diagnostic findings and patient lifestyle factors. Our nutritional approach emphasizes whole foods while addressing specific dietary restrictions, with ongoing support to ensure sustainable changes that improve digestive function and overall well-being through targeted nutritional interventions.
Digestive Health Coaching
Continuous support throughout treatment includes guidance on implementing dietary changes, managing symptoms, and tracking progress. Our team provides practical strategies for overcoming challenges associated with digestive disorders, combining medical expertise with behavioral support to optimize treatment outcomes through patient empowerment.

Absolutely amazed by my experience with the IBS Treatment center. For YEARS I've struggled with IBS and had seen so many doctors, gastroenterologists, even was hospitalized a few times, and never found answers or help. Within the first 11 days of getting my test results and changing my diet around I noticed a massive change. I felt energized. For years I was exhausted ALL the time, and for the first time in a very long time I started to have my energy back, and now it's been a month and everyday I wake up feeling alert and excited.

I used to suffer from so much pain and discomfort, really severe bloating and stabbing cramps that could leave me in bed for days. I'm THRILLED to say that I no longer feel this way. I know this is a journey that is just starting and might have its waves, but I feel so much happier and better prepared to handle it all. Dr. Diflorio is a dream to work with. I really felt like for the first time I was being listened to, and properly understood and cared for. Couldn't recommend more!

My gratitude and thankfulness to IBS Treatment center can not be expressed enough! I can't put in to words what Dr. Greer and the team at IBS Treatment Center has done for my life. Prior to starting treatment, I had spent two and a half years in and out of the hospital, with flare ups due to unknown allergies. After trying many diets, and many trips to the GI with no answers and no help, I finally reached out to IBS Treatment Center.

Given all of the countless solutions I had tried before and failed, I was a little anxious to see how this would all turn out. IBS treatment center provided tests and pin pointed exactly what my issue was and then Dr. Greer explained in depth what was wrong and how to fix it. Assuring me that I would get my life back. It has been three short months and the road to recovery has been mind blowing to say the least. Dr. Greer and her team are the most helpful people I have met in dealing with medical and with IBS. I feel like they have put me on the path the regaining and living a full life again. I only wished I had reached out sooner. Thank you Dr. Greer, Erika and Sabrina. You are extremely invaluable.

Going to the IBS treatment center has changed my life. I suffered from IBS for over 4 years, which ruined my overall quality of life in high school and part of college. I went to many different doctors at my health care provider and NOTHING worked. I have tried medicines, diets, therapy, EVERYTHING. and yet I felt exactly the same. Now, at the IBS Treatment Center, I felt that my Doctor, Dr. Greer, really listened to me.

She understood me and my concerns and was very knowledgeable. After the initial tests, we came up with a plan--a new diet, some supplements, and her help whenever needed. That plan literally changed my life about 2 weeks into it. My symptoms immediately decreased. The constant stomach aches went away. The only time I have had a stomach ache since is when I accidentally messed up the diet! Her treatment really works!

I have energy to do things throughout the entire day, my stomach does not hurt anymore, my symptoms have decreased, and I already feel like I am taking my life back in control. Thanks Dr. Greer! Overall: Do it! Stop suffering and go to the IBS Treatment Center

I have been a patient for several years and have found the staff and Dr. Wagen EXTREMELY helpful with my issues. They always show a concern for my needs and are very responsive. As far a resolution of my IBS. It is resolved IF I follow the doctor's orders. When I don't, I have issues. Bottom line. The results are up to me based on the advise received. Thank you for being there for me!

I was dealing with IBS for a little over 1 year prior to finding this center. I had gone through tons of specialists and testings throughout the US and even consulted with doctors in Mexico. Despite all the diets and medications I had tried, I continued having terrible cramping pains, constant diarrhea, daily fatigue, etc. I had come to a point where it was interfering with many aspects of my life and I was starting to really give up hope.

After starting my treatment with Dr. Greer, within about one month, I started to see progress and for the first time I felt like I was getting better from my symptoms. Dr. Greer and her staff are all amazing and will take the time to answer all your questions. I have never felt rushed during any of my appointments and they make sure you are treated with only care and compassion. My life has been completely turned around and I can't thank the IBS treatment center enough. I wish I had found this place a year ago but am glad to be on a healing path now!

I had allergy testing and office visits in Santa Monica, and did nutritional counseling over the phone with a staff member in Seattle. The original intake was very thorough and was reminiscent of going to an acupuncturist. They spent 30-45 min going over my history and information. I felt very heard and understood. The follow up I did on the phone and we went over my allergy test results. They have a great Patient Portal that has all my allergy test results, appointment and treatment notes, supplement schedule, and nutrition plan and recipes. It was very helpful to see that my allergies are on a spectrum and some are slight intolerances and others are off the charts. Changing my diet has really helped and so do the supplements.
