Meet Our Board


Mark Dixon, President

Father of Tori (7th) and Thomas (8th), living in Morrisville for 11 years.  Grew up in Michigan and worked in the automotive industry before moving in 2010.  This is my 4th year leading a PTA (2nd year at ARMS), and very proud to be an involved parent where I can have a positive influence on the next generation and help to ensure that our teachers / staff are much appreciated.  Previous board member of 5 years at Carpenter Elementary, serving as the leader in 2018-19.  In 2019-20, was reassigned to Parkside Elementary, where I formed and led the PTA in the inaugural year.  Also, the Chair for the Morrisville Public Education Advisory Committee in its first year and current member today.


Tammy Petschke, Vice President

This is my 2nd year on the ARMS PTSA board. My youngest son Jack is in 7th grade (Track 1) and my older boys are in 10th and 12th grade at PCHS.

I have been actively involved with the PTA since moving here from CA in 2011 when my boys started at Carpenter Elementary.

In my free time I enjoy walking, going to the gym, watching my boys play baseball and soccer.

Being part of the PTSA the last 10 years has been one of the most rewarding ‘jobs’ I have ever had. I recognize that the majority of parents aren’t able to commit to volunteering full time, but I can guarantee that there is something on our list that can fit into any schedule. Whether it’s assembling some teacher gift bags, sending out some emails or taking an hour to help set up a teacher lunch at the school, there is a way to be involved.

Tamara Baker Thomas, Secretary

I'm Tamara Baker Thomas, ARMS's PTSA Secretary. I've held a number of secretarial positions with other national organizations, so it was without hesitation that I volunteered for this position.  Having recently relocated from Kansas, where we lived for 6 years, I have two students (6th and 8th) attending ARMS!  Prior to Kansas I resided in Tampa, FL, where both of my children were born and raised.

Originally from Virginia Beach, VA, I am a Professor in the Psychiatry department at UNC-Chapel Hill's School of Medicine.

When I'm not busy with work, I consider myself to be a 'foodie' at heart, trying lots of new cuisines. When I'm not eating, I enjoy tending to my plants, biking, step aerobics, traveling, and learning new languages.

I'm excited to serve in this role on the Board of Directors, as ARMS is such an amazing school, with wonderful staff and students!

This is my second year volunteering at communications at ARMS PTSA. My daughter, Ava, is in 7th grade – Track 4.

I was born and raised in India during the initial part of my life. I moved to the Cary/Morrisville area in 2000.

By profession I am a Software Engineer, hence my passion to volunteer in communications. I am looking forward to a wonderful year working with staff, parents and students and help ARMS in any way I can!

Megha Jain-Tailor, Member at Large

I’m Megha Jain-Tailor and serving as member at large for the PTSA this year. I have a daughter in 6th grade (Dia).

We moved from Zambia about 8 years ago and have been in Cary ever since.

I became active in the PTA when Dia started kindergarten at Carpenter and I’m still an active member there as her brother is in 4th grade.

I love volunteering and excited to learn more about Alston Ridge Middle School. It seems like a great community of teachers and parents so far.

Unless someone like you cares a whole awful lot, nothing is going to get better. It's not.
