Mark Dixon, President

Father of Tori (6th) and Thomas (7th), living in Morrisville for 10 years.  Grew up in Michigan and worked in the automotive industry before moving in 2010.  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 newly formed Morrisville Public Education Advisory Committee.

Tammy Petschke, Vice President

My name is Tammy Petschke and I am your PTSA Vice President for 2020-2021. I have 3 boys: Jack (6th), Kyle (9th) and Josh (11th). 


I am originally from Buffalo, NY and my husband and I moved to California in 2001 where we started our family and lived for 10 years before settling in  Morrisville in Fall 2011. 


I became active with the PTA when Kyle started 1st grade at Carpenter Elementary and continued until Jack graduated from 5th grade in 2020.

It's been a great experience being part of the ARMS PTSA board. I love being involved with this group and have enjoyed forming new friendships and being reunited with old ones. 


When I'm not volunteering I enjoy reading, spending time at the gym, walking, playing tennis and serving as a member of my HOA Board.

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!

Michalene Lee, Advocacy Chair

I joined Alston Ridge Middle School in July 2020 as the 6-4 Math Teacher! I am a graduate of Elon University, where I majored in Middle Grades Math Education & History.


When I'm not teaching, you can find me running, or traveling. I joined the PTA board because I believe that family support is critical to student success, and the PTA is vital to building relationships between teachers, students' families, and the surrounding community.


Lori Potter, Membership Chair

I’m Lori Potter and I’m serving as Membership Chair for the PTSA.  We joined the ARMS community last January and are very excited to be here!  I have 2 children on Track 4, an 8th grader and a 6th grader.  I have two older kids at Panther Creek High School in 11th and 12th grade.


I am a Raleigh native and have lived in this area for 13 years.  I’ve been involved with PTA in the past at Carpenter Elementary and Cardinal Charter Academy.  


I am a travel agent with TMC Travel specializing in family vacations.  I love to travel, especially to Caribbean and Disney destinations.  


I’m looking forward to a great year at ARMS, excited to serve our school community and help make it a great year for everyone!  


Tiffany Grignon, Treasurer

Tiffany is an advocate for financial literacy. When she's not working, she is volunteering with the Junior Achievement Organization and teaching financial lessons in the schools. Tiffany loves traveling, experiencing different cultures and she loves to play video games. Tiffany has one child who is in the sixth grade.

Unless someone like you cares a whole awful lot, nothing is going to get better. No it's not.
