"Dr. Kat was amazing to work with! She diagnosed my son with autism (he had been to a specialist in the past who said he didn’t have it, so this really helped us to understand him better and get the right treatment such as ABA therapy to help him). She also worked with us to find the right medicine and natural supplements to support his ADHD and anxiety. This also included some testing to gain some additional insights as to which medication would work best for him. It was great to have a doctor that really put my son and his needs at the center of the care circle. He is now getting great reports from his school and is a much happier teenager (which makes the whole family a whole lot happier!) Thank you Dr. “Kit Kat” as my son likes to call her."

"Yellow Brick Clinic: Integrative ADHD, Autism, Developmental-Behavioral Health is a place of hope for our family. The staff is kind, courteous, and willing to do what it takes to help any person that walks into their preview. Dr. Kat is the best! She is smart, funny, and intuitive. We truly wouldn't be where we are today as a family if it wasn't for YBC. The positive changes to our physical and emotional health has allowed us to reconnect and become closer to each other. Thank you!!!"

-Parent of three elementary, middle, and high school-aged patients

"Hi Dr. Kat,  First, HAPPY VALENTINES DAY!!   I wanted to also say, Thank you so much!!  You are one of the most pure hearted, compassionate, and determined medical professionals I have met. You told me in the beginning when, I was at my mentally weakest point that you would not give up.  You kept that promise and today was probably one the beat days we have had in a long time.  My son had a calm enough body and focus to play UNO with his daddy and brothers.  So blessed thank you so much!!" 

-Parent of young man with developmental disabilities

"Getting the right diagnosis does matter, and it's very relieving to finally have it. I have been bounced between mental health professionals for years and given the wrong medications over and over, making my health worse. With the correct diagnoses, I can get the accommodations and support I need. Knowing I have EDS helps both me and many of my family members figure out how to take care of ourselves to avoid pain and injury in the future.

My last psychiatrist said "horses not zebras" to me without ever thinking outside her box. I think doctors need awareness of EDS, and psychiatry needs awareness of autism and ADHD in their patients. Not all physical pain is from depression, and not everything they don't understand is a personality disorder. I have been this way my whole life, but I also don't want psychiatry to think it's all bad. Not all my differences have to be fixed, and with the right diagnoses, so many things finally make sense."

-College student patient

Dr. Mandie is a fantastic provider. She really cares about her patients and takes the time to fully understand their unique situations and needs. Her process is very thorough and I have found her to be patient, kind, and empathetic. I would recommend Dr. Mandie to anyone who is looking for a great psych professional to support them on their healing journey!
