    Refills are often withheld unless an appointment for a checkup is scheduled. During a six-month…read moreperiod, there were no follow-up phone calls to assess patient status and minimal outreach overall. This pattern seems to recur specifically at the time of refill requests, creating pressure to book an appointment in order to receive medication. The communication through the Healow app has also been disappointing; responses from staff have been unprofessional and unhelpful. Overall, the level of service has been very POOR. The front desk staff are awful, Stephanie in particular. Called 5 times and was hung up on all 5.. again a doctors office with no customer service is not a good one I have worked in healthcare for nearly 20 years and have never experienced patient care handled in this manner. I would encourage prospective patients to be aware of these issues before choosing this practice. And last but not least if you disagree with them, they delete you off the Healow app with MY patient records and cut access to your medications..

    Avoid this facility! You make an appointment to see the DOCTOR, pay to see the DOCTOR, call confirm…read moreyou will be seen by the DOCTOR, and end up with a nurse every single time. Never able to fully address your concerns, leave messages for the the doctor or his assistant to call you back and nothing. They treat you like a ping-pong ball. HORRIBLE service by all especially their receptionists!

    I was under the care of Dr. Rafael Rivas-Chacon, MD - Pediatric Rheumatologist, starting in 2013…read morefor autoimmune symptoms including fatigue, chronic pain, dry mouth and eyes, and hormonal irregularities. Despite having a clearly positive thyroid peroxidase antibody result (TPOAb = 109 IU/mL) -- a textbook marker for Hashimoto's thyroiditis -- Dr. Rivas-Chacon dismissed it and instead diagnosed me with SLE (lupus), Sjögren's syndrome, and rheumatoid arthritis, without confirming those diagnoses through appropriate criteria. As a result, I was prescribed Plaquenil (hydroxychloroquine) for years. That medication, which I now know I may never have needed, caused permanent retinal toxicity, tunnel vision, and cataracts. I live with irreversible vision loss that could have been avoided if Hashimoto's had been recognized and treated when the evidence was right there. It has taken me over a decade to finally uncover what was missed -- that Hashimoto's thyroiditis was likely the root cause all along. This doctor's dismissal of key lab results and mismanagement of my care has profoundly affected my life, health, and independence. I urge anyone seeking autoimmune care -- especially women -- to insist on full thyroid testing (TPOAb, TgAb, TSH, Free T4/T3) and to get a second opinion if you're being diagnosed without clear evidence. This experience has changed my life, and I want to prevent it from happening to anyone else.

    Dr. Rivas-Chacon is a lifesaver! He has been treating my daughter for her Lupus for 30 years and…read moreme for my RA for 25 years. He has kept us both healthy and in remission for all these years and has always been there when we need him. He is the only doctor I have ever known who will return your call on the same day regardless of the time. My daughter is now dealing with Chrons disease and even though this is outside his area he is following her case and working with her current doctors to make her well. I thank God we found him when she was young and would not trust anyone else. The wait to see him can be long but is so worth it, I would not trade him for the world.
