“She explained how I should understand my insurance better and that I actually didn’t need a referral from her to get treatment with my insurance.”

She has your health in mind, but she reminded me of everyone’s favorite Aunt who’s coming in to check on them.

I don’t like the way provider treats me, she not even care about my symptoms, she said that is because I’m old and i don’t want to accept it. From 0 to 10 I give her 0. She even said that I have really bad depression symptoms which is not true, I don’t make my appointment because I feel depressed. I make my appointment because I going through menopause symptoms and she said that we all women’s have going through. And she right about that. But I talk to her about all my concerns and she those not care.

I felt unheard and just rushed along. I saw the doctor for all of 10 minutes which could have been a phone call as she just prescribed meds and left even after expressing my concerns with medication

Unfortunately had an interesting experience as a first time patient. She had not read my detailed patient intake form, so she misunderstood why I was there. I had just seen a doctor 4 months prior for a well check, but I could no longer see that doctor in future years because I am turning 26 and will be kicked off MDVIP. I recently got married and my husband hasn’t been to the doctor in years. I decided we should start looking for a new doctor together to find who we like.
I also wanted to ask a few questions about my health to get advice.
When she came in, she sounded very disappointed in me for being there since I had just had a well check. I felt like I had to defend myself for being there, for she kept asking me questions like “why are you really here” in an annoyed tone. I had to ask her if I could tell her about one of the things on my patient intake form. She rushed the appt, but I just wanted to get out of there as possible anyways since I was on the verge of tears.

Not only did she refuse to refill my adderall prescription during a time when the government has already been making it hard enough to get access for the past 3 years, she was condescending, dismissive, and rude towards me about my diagnosis. I understand it can be an addictive and abused substance, but she never asked me any questions about my usage, just about my past doctors. It’s okay if she doesnt refill adderall at her practice, its okay if she has personal hangups about the drug, but she couldve told me that without being unprofessionally rude. The exhasperated sighs, scoffing, and head shaking, and the rant about her disdain for telehealth made me feel like she saw me as a stupid misdiagnosed addict, and not as a patient seeking healthcare she wasnt able to provide.
Front desk and nurses/assistants were incredibly kind and hospitable. Doctor had the worst bedside manner I’ve ever experienced and I will not be returning to this practice.

I have been a patient of Dr. Maressa Alejandro-Reyes for several years now. I trust her completely, which is why I’ve followed her -over the past 16 years-wherever she’s moved in her practice. She is incredibly caring, a genuinely good listener, and always takes the time to understand my concerns without ever making me feel rushed.
I’m truly grateful to be under her care.

Dr. Alejandro was so kind and nonjudgmental. I trusted her immediately, and am actually looking forward to my physical next week. I have found “my doctor!”
June 11, 2025Petra J.Verified patient
I would not recommend this provider at all. They were more concerned with insurance than patient care. I left crying and annoyed.

She doesn’t know this yet, but I’ve adopted Dr. Maressa as one of my aunties. No one gives hugs and kisses on the cheek the right way, except your auntie and I’m claiming her for mine. I know I’m in good hands because she was completely anxiety reducing and I can tell she TRULY cares about my health and wellbeing, with only ONE visit. Looking forward to my follow up. Thank you!

I was extremely comfortable with my visit!!!
January 21, 2025Cortez D.Verified patient
The Doctor has a Holier-Than-Thou attitude. How dare you take 1 look at a patient who has a Fatal Congenital Disorder that just because you never heard of it dismissed said patient and instead of helping them with what they were in need of instead you recommend mental health services. Never looked at the years of medical records, tests, and x-rays that were all with me during the short appointment . Did not try to learn anything about me or my condition nor cared to. They assumed because of the request that was made, I was something other than what I am and would not even listen as I tried to explain the situation that brought me to them. Horrible Doctor, horrible person.
