    Not good. Disorganized and bad preparation. I went in for a screening and they accepted me for a study. There was two weeks until it started, so I organized to be away from my home for the 16 days it was taking place. I received nothing in writing to say I was accepted. I received two phone calls, one to say I was accepted and to arrive at 6:30m and another saying they had me sign the wrong study and do I could arrive 7am to sign the right paperwork. I called them once to ask a few questions being that i have never done a study before, that was also a topic we covered. They had me confirm a few times that I would in fact be willing to do the study. Come to day of, arrive at 7am, fill out forms, the staff give me these obscure directions as to where to go next, "cross the street, next to the roundabout, look for the glass building." anyways, I park my car and try to walk over and get another call from someone there who also wasn't able to tell me exactly where I had to go. When I asked is it such and such building they couldn't tell me ( they go there every day). Anyways, I get there and get into the research facility. It does not feel good. It is lab rat conditions. Yes, it's clean but they have saddled three beds into one room with 2ft between them. The bathroom is sink, toilet, shower. They give me the urine test cup and I use the restroom and give it back. By around 9am they scan my barcode wristbands and ask me if I ate anything to which I respond Yes, a banana at around 5am. Now I find out this is an issue. they tell me then that I'm supposed ot arrive fasting. Since I received ZERO paperwork confirming the study, no one called me the day before, I had no way of knowing this. So they tell me I cannot participate in the 2 week study. This was not good news given it took 3 hours to drive there. I offer to wait until the time has passed and they say no. I ask to be compensated for my time. It should be $450 for the day. They asked if I could be phone backup for tomorrow I say yes, that should be $450 as well, $900 total. Both disappointed and frustrated knowing I'd be driving back 3 hours, I'm already tired. So I get my luggage and leave. I've called them to discuss this further and got the voice mail. At around 3pm i get a call back from the person who let me go. I asked if they are still wanting to have me as a phone back up and they say yes. When I ask about compensation they say... "your urine test showed positive for ECSTACY, so we cannot have you for a phone back up and you cannot be compensated." Now I know I haven't taken any ecstacy. I know you all reading have to take my word for it but there you have it. So I say that's completely wrong and I will go get a drug test myself and show them. I do that and there's nothing indicating any drugs in my system. It seems this is a tactic used to avoid compensating. It was extremely rude and time wasting, it is clear they see their "subjects" as simply that: a test body to poke, prod, when they need to. Overall I am very relieved I didn't 'subject' myself to such conditions. People say they have repeat visitors but i couldn't see why people would want that. The paperwork I had signed stated $11,000 compensation for 3 weeks and the one I'm supposed to go for is 2 weeks $7k. That's a good bit of money but I dont think it's worth putting your body through all the disorganization and mistakes. While I was researching I searched Parexel in Reddit and a lot of clinical staff from other companies said of Parexal that they spend more time fixing their mistakes. I truly feel like I dodged a bullet and I hope I can not be in this situation where I have to choose money over my safety and wellbeing. I wouldn't trust they would take care of me.

    I'm very happy here at Parexel. They treat me like a King. Thank you Sona(my charge Coordinator/Nurse)for being so good to me.

Yes, he has a great location, lots of parking ($5) and an office with impressive abstract paintings. What really sets him apart is THAT HE TRULY CARES AND CONSULTS WITH THE CLIENT 100%. Unlike my previous psychiatrists who would meet me for 15 minutes to glance at my chart and give me medication to try, Dr. Yang looked at everything, and I mean everything. He requested all past medical records to make a decision on which medications to suggest. He took into consideration my body's reactions to previous treatments and external factors. Had it not been for him I probably would not be alive. He met with me every two weeks for an hour, we would converse for 30 minutes, and go over medication and literature for the other half hour. He has completely honest about the pros and cons of each prescription, and if I was willing to try it. He never sugar coated anything, and I think that helped a lot. He also had a good idea on how my body would react, and he was always right. I am glad my friends helped me pay my initial consultation, and for Dr.Yang who did not turn me away but provided a payment plan for me after evaluation. Now I am enjoying my 30's and planning for the future. I did not think I would make it to see my 30th birthday before coming to Clarity Mental Health. This place goes beyond the call of duty for their patients. I always felt understood and respected on all levels. His office has a different entrance and exit for privacy and he never runs late, they answer all phone calls and I never had any problems with my pharmacy or paperwork. Extremely professional and trustworthy. Thanks to Dr.Yang, I am thriving and enjoying life today.

    Dr Mizani is a miracle. When my therapist insisted I change…read morepsychiatrists from my last one to Mizani, I was reluctant because I thought "all psychiatrists kinda suck, I might as well deal with the one I have because it doesn't get much better." I have dealt with quite a few psychiatrists in my time, including at treatment centers; and all but her have supported this idea I had that psychiatrists have no emotional intelligence, but just a purely clinical view of the human brain and don't view patients as people to listen to but subjects to examine and push drugs on, always thinking they know better and saying insensitive things to invalidate my real struggles. But not her. She LISTENS. God, I have never met a psychiatrist who listens and really LISTENS like her. She cares what you have to say and takes everything you say seriously and into account before all of her carefully thought out decisions. She makes me feel seen, respected, taken seriously, cared for, and listened to. That's a rare find. And she really knows what she's talking about; her knowledge of psych and medication is very impressive beyond expectations. As soon as I started seeing her, she was able to immediately help what was wrong with my meds and change things around to the right mix. She always lays out multiple options (some containing adding meds, but always presenting alternatives and respecting any apprehension to meds), and takes the time to listen and weigh things out to whatever you feel is best for yourself. She helped refer me to mental health treatment in August when my depression was at its worst, and though the treatment was incredible, the psychiatrist there just couldn't compare. It reminded me of how lucky I am to have Dr Mizani, the best of the best. I have depression, anxiety, and a past of an eating disorder and she has been nothing but helpful and wise. These problems are big in my life but she has kept them under control like no other, and when they get less manageable, she finds the right solutions (like when she strongly encouraged me to go to treatment and provided those resources). Finding mental health professionals who know how to handle eating disorders and don't say totally triggering and incorrect things about them is surprisingly difficult, but she is one of the few who knows what she's doing and doesn't say triggering things. If you're struggling with your mental health and like me have fear around psychiatrists and their lack of emotional intelligence, please give Dr Mizani a try. She's different. She's gold.

    I was referred Dr. Mizani when I was pregnant, dealing with anxiety and let's face it, I exhausted…read moretalking to my girlfriends about my issues and marriage. I would say I am a type A personality and I like things under my control. Pregnancy, however, turned my emotions on its head. Thanks to a surge of hormones, everything made me highly irritable and aggravated. I knew, or hoped, that it was just the pregnancy. I decided to seek help because I wanted my pregnancy to go smoothly. Dr. Mizani was the perfect person to hear me out. She heard me out and used her expertise to see patterns in my actions and offered me ways to approach concerns I had differently. She got mad with me, when I was mad, and she validated me just enough that it opened the gates to tell her more of what I was dealing with. She was able to discuss sensitive issues about my marriage that didn't make me feel embarrassed. She is highly professional and very experienced with working with personal matters and intimate matters of the heart and soul. I am so glad I was able to have her be my doctor . She is so well read, researched and up to date in her therapeutic approach. I have since referred two other friends to her who are also equally satisfied and comfortable with Dr. Mizani.
