I have been a patient of Dr. Breen from about three months. In this time I've had the chance to see him both do his job of providing medical care and guidance with at a very high level of competence and with attention to detail. Not only do his job but provide the promised / implied action of follow-up contact and monitoring changes in patient condition. Not only Dr. Breen, but his staff has proven equally conscientious, business-like and professional. I am very pleased to have been referred to Dr. Breen, and would (this is a rarity) willingly recommend him to others.

To be completely honest i have known dr breen for over 30 years. He is a close friend. That does not alter or influence my review. Here is my story and ill be brief: sean called me out of the blue 6 months ago. I was hurting, out of shape, going to the gym with poor results. Im 42 years old. Was 217pounds at the time. He sent me for blood tests. A few days later let me know major changes were needed. He put me on the necessary supplements/ testosterone replacement therapy and i have had a complete turnaround. My life was saved, my marriage was saved and my future is bright. Lost 10 pounds but more importantly i am mostly muscle now..those are the facts.

I saw Dr Breen to basically find out what my body was deficient in and what supplements, vitamins, herbs ect...I should be taking.He ran extensive blood work on me and basically told me everything about my body inside and out. I'm a very healthy 45 yr old woman.I work out, eat healthy and I'm in great shape.Dr Breen basically made me aware of things my body needed to continue my healthy lifestyle and continue to look & feel younger as old age tries to settle in.I am experiencing positive results using the items he recommended for me.He's a great doctor & very knowledgeable about keeping the body healthy from the inside out.Definitely a tremendous learning experience

Not many patients are aware that Dr. Breen served as a General Medical Officer with the United States Marine Corp and was awarded the Navy and Marine Commendation Medal with V for valor for his service in Iraq in 2003. Since his discharge in 2007, he has devoted his career to helping his patients achive optimal states of health. I have trusted him with my life and you can also; I can recommend him without the slightest hesitation.

by Csoljak on May 6th, 2013

I was diagnosed with Graves Disease and Thyroid Cancer 20 years ago and due to the standard treatment and medication (synthroid and levothyroxin) , I have struggled with poor health and excessive weight gain since that time. In addition, along came the onset of menopausal symptoms and Type II Diabetes due to the obesity. My HMO doctor(s) all warned me to lose the weight or I will die in a few years but with my severe food allergies, none of them were able to tell me how to lose the weight. I have tried every diet program advertised, old wives tales bought and paid for programs, joined every gym, joined the circle of Curves program and was not successful and losing any weight. Finally, I met Dr. Breen. We discussed my condition and how to properly understand my test results for thyroid, glucose, blood pressure and he ordered bloodwork to test my hormone levels and vitamin D. We scanned my corotid artery for plaque and did a Body Fat Analysis. As a result of these tests, we switched me to Armour for my thyroid, began bio-identical hormone replacement therapy for estrogen, progesterone, testosterone, Vitamin D, and DHEA and a few different supplements, along with Amazing Green Grass (raw vegetable powder) and I learned how to eat like a dinosaur. For the first time in 20 years, I am walking 2-3 miles per day and to-date, I have lost 22 pounds. The weight is going down slow but steady and I am amazed at the inches lost and can see the actual results through his InBody bod fat analysis equipment. I feel awesome. My mind is clear, my energy level is up, my libido has gone up significantly and I have access to Dr. Breen 24/7 if I have questions or concerns. Thanks to Dr. Breen and the awesome collaboration of my new HMO doctor, I am on the road to good health and currently training to run a Marathon. Dr. Breen, YOU ROCK!

I was consistently been between 230 - 240 lbs for my entire adult life until going to see Dr. Breen. I thought I was in shape, but after doing a detailed weigh in and assessment, I was nearly 25% body fat. I had just undergone a second back surgery and I really wanted to do something to get my weight under control. Dr. Breen put me on a course of hormones and recommended a dietary plan for me. In six months I went from 241 Lbs to 215 pounds, from 24% body fat to 15% body fat, and a size 38 waist to a size 34. The weight loss was slow, but steady and consistent. When I got fitted for some new suits they had to get the trousers from the factory because they could not be taken in enough to fit correctly. I was beaming with pride. At 42 I am surfing, running, and lifting like a man half my age. It is a new lease on life and I owe it all to Dr. Breen.

I went to Dr Breen 6 months ago to treat me for menopause. I found him on the Suzanne Somers Forever Health network which has doctors who specialize in bioidentical hormones. He spent about 30 minutes on the phone with me up front and then sent me for blood work. Within a week I went for my 2 hour consult and he explained all my hormone levels. He was extremely knowledgable and spent a lot of time teaching me about how hormones work. Since starting hormones I feel amazing. I would highly recommend dr Breen if you are looking to get treatment for menopause.

 |  Testosterone Treatment: highly recommend  |  show details
by Derek on May 2nd, 2013

I found Dr Breen after 2 doctors refused to treat me with testosterone because my level was 376 which was not low enough for them despite the fact I had all the classic symptoms of low T. He was extremely thorough and explained that the medical literature shows increasing my levels reduces my risk of dying by 30%. I've been on testosterone, DHEA, armour thyroid and high dose vitamin D for 3 months and have never felt better. At 39 years old my libido is where it was at 19. Dr Breen spent 2 hours with me during my initial consult and my hormones arrived the next day in the mail. He was extremely thorough and followed up my blood levels 4 weeks after starting therapy. His staff (Carrie) is super friendly and his office is very peaceful. I highly recommend Dr Breen to any guy seeking testosterone.

I was diagnosed with cancer. Dr. Breen was very helpful not only with a medical marijuana but with my diet. I thought the visit was professional, time to wait was just as long as if you went to your primary care dr.
