I’ve been a patient of Dr. Angel Rivera at iSquared Medical Group for years, and the quality of care here is exceptional. Dr. Rivera is consistently knowledgeable, thorough, and genuinely attentive during every visit. You can tell he takes his patients’ health seriously and puts real thought into his guidance. His staff is excellent as well—friendly, efficient, and always professional. It’s rare to find a clinic that runs this smoothly while also making you feel welcomed and supported. I strongly recommend Dr. Rivera and his team.

This should be called weight loss clinic for the bored and rich. I saw Angel Rivera, DO first, horribly belittling from the start. I told him I have exhaustion, weight gain, excessive hair fall, hives, faint when I stand too quick. He was annoyed at the last one because he had to take an extra 5min to run a heart test. He said nothing was wrong with me and literally did not run blood, sent me on my way. Wanted me to do a $100 in body scan. Denied the first visit. I went to Sejal Gehani, FNP to try a woman dr, thinking she’d be more compassionate and interested in my case. She literally told me to do squats. I’m 145lvs at 5’4” by the way which is perfectly fine but I gained 20lbs in a few months with no lifestyle changes. On this visit she convinced me to pay $100 for the in body scan- the only information I remember receiving from that scan was to see how much body fat I had. They literally just want your money and are awful drs in my opinion, they give hydration ivs and sell expensive supplements. At a different office they were able to identify that my ferritin was at 8, low b12, Mcas, and high eosinophilia.

I've been seeing Alison Brown-Ferguson for just over 6 months and she's fundamentally changed the way my body moves. I study physical therapy myself, and every treatment technique I came across failed to improve my shoulder and spine mobility. Alison was able to unlock full range of motion in my shoulder within one session, and a few sessions after that my spinal extension and rotation improved immensely. Her Fascial Counterstrain methods are unique and I hope to study it and integrate it into my own practice, but I'll always go back to Alison for my own treatment. 5 stars doesn't do her justice. I followed her to I-Squared Medical, it's an impressive clinic and her private treatment room is very comfortable.
