While I enjoyed the Low-T Center and team, which I thought couldn't get any better. Well it did. In my opinion the ownership of SynergenX made many great and strategic business decisions from the change from Low-T to SynergenX that ultimately benefits their customer. First, they started with hiring the right people. The ownership and leaders of SynergenX truly have a wonderful team. The SynergenX team is always happy to see me each week and make sure all my needs are taken care of before I leave. They just make me feel good to visit SynergenX each week. Toni and Daisy are awesome PA's and they have the best strategic care plan in mind for me. They tailor care plans to the individuals needs by truly listening to the customers and completing a thorough assessment. The balance of the team is awesome and I can tell they all work together as a team to best serve the customer. Also, SynergenX added a ton of new services over what I was able to receive from the prior Low-T Center. To maintain a strong overall sense of well being and positive health as we all grow older, I would highly recommend visiting SynergenX Health for both men and women.

She put me on Synthroid, and when I told her I was having significant side effects, she totally ignored me, did not change my dose.. it got so bad that I was suicidal because of the medication.

She is the worst doctor I have EVER dealt with, abusive, hateful, doesn't listen to her patients, and should NOT be able to practice. STAY AWAY!! Also, the office itself is a hot mess. Constant reschedules, waiting an hour to see her so that she won't listen to you anyway.. just the absolute worst in every way possible.

I received a text message to ask me how my last appointment was. I complained because it wasn't very good. It was with Dr. Sheas Nurse practitioner Jennifer. My wife was with me and experienced the unprofessional manor of the appointment. So because I complained they deleted my patient portal and sent me a letter stating they would no longer see me. They just didn't even look into the problem, they just dumped me. As of now they will not give me the results of my bloodwork I had done, they will not respond to the pharmacies request because Jennifer wrote the prescription wrong, so I can't get my medication. I am just amazed at the unprofessional manor in which this was handled. I don't have my medication because of them. That's a big problem. It's sad I have to take this to the next level because I have been a loyal patient for years despite all the problems with wait time and staff.

I did appreciate that she called me almost immediately. However, rather than smoothing things over as you would expect a practice manager to do, I felt she was defensive, cold, and unfriendly. She completely turned me off from wanting to continue with the practice. She said it was not a good fit and I agreed. Even if the doctor is good, these are not administrators I want to be regularly dealing with. Extremely disappointed in my experience.

I saw Castaneda years ago when my insurance changed and I was no longer able to see my regular…read moreendocrinologist and ended up seeing her for about a year or so, it's hard to remember. Her receptionist was always pretty rude but not why I'm here. Dr.Castaneda is very "old fashioned" as in extremely blunt and flat out rude. She'll tell you what you may not want to hear, and I thought that's what I needed at the time. I was obese for my age (15) and have been seeing endocrinologists since I was 9 due to my thyroid being removed at that age, I was dealing with multiple mental illnesses from childhood trauma, including pretty bad body dysmorphia that led me to develop an eating disorder. I hated myself and my body and Dr.Castaneda was the "harsh truth" I thought I needed to get my life on track, but that was not the case at all. When I first visited her, she had me remove some clothes to examine me (not out of the ordinary for any endocrinologist I've seen), and began commenting on the shape of my body and how I'm ruining it with my diet. She pointed out every flaw I despised about myself including my body hair, acne, stretch marks and hyperpigmentation, depression/anxiety and blamed it all on my weight. Though her intentions were to help, this sent me spiraling for months after, hating my body even more than before. Looking at my body in the mirror and seeing "what I'd done to myself" impacted my mental health in the worst way, after every visit I'd go days without eating, spending an excessive amount of time sleeping (12-18 hours a day) then would end up binge eating until I made myself sick, all to punish myself. I even ended up taking my medication less and less because I couldn't bring myself to care anymore. I dreaded every visit with her because I knew I'd "be in trouble", she'd yell at me (yes, actually yell) for not changing my diet or exercising more. I gradually became more and more depressed until I began having suicidal thoughts, luckily my family changed insurance again and I was able to return to my normal doctor. For the record, I see my doctors for my thyroid issues, never for my weight. I never faced any issues with blood sugar, blood pressure, cholesterol or any of that besides from some vitamin deficiencies, and I understand that my diet and physical activity needed major change if I wanted to continue to be healthy, but that being said, during my time with her, I was never actually "unhealthy", I was fat. Her concern was with my health if my weight went up and my bad eating habits continued and I understand that, but making my appearance the motivation for losing weight is not the impactful genius tactic you might think it is. My mental illness is not her fault by any means, as I said I'd dealt with childhood trauma that left me with many self esteem and body image issues, but the approach she took when addressing my weight was not only super unprofessional, but extremely harmful and dangerous to my mental health. I expressed my issues and concerns around this and she never once recommended I see a therapist or psychiatrist, she resorted to scolding and shaming me for doing this to myself, I would break down in tears in front of her literally every visit and she never once thought that maybe my weight wasn't the only issue here. Her blaming me for the mental illness I had absolutely no control over was one of the darkest points of my life. Now as an adult, almost ten years later, I've been able to address my weight, my mental health and relationship with food and my body. People like Dr.Castaneda will say things like "I don't sugarcoat", they claim they refuse to enable such unhealthy behavior but don't seem to understand that taking care of your body starts with the mind. It starts with very basic things like brushing your teeth, washing your face, things that may seem like a no brainer to most people, but the reality that a lot of people don't see is that some people are not capable of even those simple tasks, a lot of us hit points in our lives where we don't even want to be alive and people blame it on laziness and think that we've been babied or spoiled. The fact that anyone could ever think that I CHOOSE to be like this is beyond idiotic, no one CHOOSES to hate themselves and lose all drive and motivation to take care of themselves, it's literal chemical imbalances in the brain caused by extreme trauma. A big lesson I've learned through therapy is "my trauma is not my fault, but my healing is my responsibility". I'd like to reiterate AGAIN that I'm not blaming Dr.Castaneda for my mental health issues, they were there with or without her, what I'm saying is she approached a whole house that was on fire, and only watered the lawn. TL;DR If you have mental health or self esteem issues, don't waste your time here.
