McCullough is shown to be laconic and serious. She does not tolerate the boorish and often sexist antics of her male co-workers. It is implied that she is slightly racist towards black people. She seems to be one of the nicer guards, willing to help.
After the riot, McCullough develops a self-hating, masochistic attitude and begins stubbing cigarettes out on her thighs, likely due to her depression as a cause of the riot. She develops extreme PTSD and anxiety as a result of it, saying she wakes up in 'sweat puddles' 'jumps when she hears a loud noise' and is angry at herself as she keeps seeing the inmates as horrible. She believes they are human and just want to get through the day
Physical Appearance Edit
McCullough is a blonde white woman. She keeps a fringe and uses minimal makeup at work.
According to CO Stratman, "She could totally be cute if she got, like, 'Princess-Diary'ed".
In Season 6, she begins self-harming and has several burn makes on her thighs.
Before Litchfield Edit
Before she came to work at Litchfield, McCullough served in the armed forces in Afghanistan.
McCullough is one of the new guards hired by MCC in order for the corporation to receive financial incentives for hiring military veterans.
She escorts Maritza on van duty, foiling Maritza's original plan to charm one of the male guards into going into the house while Maria's cousin picked up the panties hidden by Flaca in the bottom of the vehicle. The two eventually form a bond, and Maritza agrees to give McCullough makeup tutorials.
While she can be uncaring towards many of MCC's policies and her fellow guards' activities, she shows concern when she overhears Maritza throwing up in the bathroom (after CO Humphrey's torture). Recalling that Humphrey improperly had Maritza in the guards' house alone, she wonders if he may have had something to do with her state, and she and Stratman discuss Humphrey's possibly sociopathic nature. They consider that Humphrey may have raped her, and worry over the implications for the rest of the guards. She debates reporting the incident but Stratman sways her decision. He explains that they are part of a "brotherhood", meaning they have to look out for one another. McCullough reluctantly agrees and chooses to remain passive on the situation.
When the guards begin shutting down the peaceful protest in the cafeteria, McCullough attempts to assist Baxter Bayley in apprehending Suzanne Warren, but she is unsuccessful and calls out to Piscatella for help.
When Caputo asks the guards if Poussey was violent following her accidental death at Bayley's hands, McCullough and Luschek are the only ones who do not respond in the affirmative, clearly disturbed.
At the end of Season Four, McCullough is shown being held at gunpoint along with Humphrey by inmate Daya. The scene ends on a cliffhanger.
McCullough eventually becomes one of the guard hostages after the prison takeover.
When the guards were forced to strip in front of the entire prison population, Flaca and Maritza took the job of stripping McCullough, who protested that she and Maritza had bonded. Later on, she was the first person to realize Daya no longer had the gun after overhearing her talking to Mendoza during the group photo.
For the talent show, she did a "helping hands" act with one of the other hostages, who took the opportunity to grope her, much to her annoyance.
McCullough was later escorted along with the other guards to the outhouses as part of Mendoza's plan to release them in exchange for having her sentence commuted, and was seen visibly crying at her situation. Later, Ruiz stole Mendoza's thunder and freed the hostages. When Ruiz was mistakenly told she could go home, McCullough was quick to correct the situation and point out Ruiz was actually an inmate, apparently still angry at Ruiz for forcing her and the other COs to strip.
After the events of the riots, McCullough, along with Ryder Blake and Joel Luschek returns to work at Litchfield, this time at Max. Later in the break room, McCullough asks Luschek how he can be this calm, considering what happened the last time they were inside of a prison. Rick Hopper and the other CO's then enter the room, and invite all 3 newcomers to Fantasy Inmate. Blake tells the others he does not gamble, but McCullough signs both herself and Blake up anyway. At the end of their shifts, Luschek invites both Blake and McCullough to a party. McCullough reveals she has taken up a second job as a taxi driver. While Blake seems concerned about McCullough, Luschek just wonders if she has gotten sexier. ("I'm the Talking Ass")
After the riots, McCullough seems to suffer from major PTSD, has nightmares, she burns herself with cigarettes as another way to cope with her feelings and drinks excessively to cope. She holds a grudge against Ruiz, hitting her in the face and picking her for Fantasy Inmate.
During kickball practice, Badison doesn't take the training seriously and kicks the ball so it gets stuck. No-one seems impressed by this, except Nicole, who laughs hysterically. Piper gets it while Luschek and McCullough help her hold the ladder. McCullough asks if Head of Rec gets extra money, because she can't drive for LYFT anymore. Piper sees the field, and Badison backs her up when Piper begs to be able to use the field. He agrees.
She becomes overwhelmed when a group of D-Block girls become upset about having to go back inside during their kickball practice, so she draws her baton and lashes out, screaming for everyone to get on the ground. Stefanovic comes and helps her calm down, (and also implying that they have sex), sending everyone inside. Later, Ward, who thought it was Wheatly smoking, climbs the stall and sees Artesian McCollough, with burn marks all over her legs. Artesian shouts at her and she apologises. She says it's fine. Ward tells her that she heard of the PTSD and McCollough says it was her fault not theirs, and that they were just excited to play kickball, but also shares that she has nightmares and panics. She empathises with the inmates and is angry at herself because she constantly sees the bad of the inmates. Ward hands her a paper towel. ("Double Trouble")
McCullough and Ruiz eventually end on somewhat good terms when Ruiz convinces her to make the girls mix up the kickball teams between C and D Block, making the block war more difficult and eventually resulting in it never starting at all. ("Be Free")
