The Executive Team
Denis McNicholl
As a recovering workaholic, I continue to fall back into old habits, thus, I have started attending WA (Workaholics Anonymous) every Sunday morning.
I do find time to practice my knitting skills, during the late evening hours when I can't sleep, and I've recently finished my first pair of mittens; next will be a wool hat.
More importantly, I'm going to spend time with my nephew so I can better utilize my tablets, phones and Photoshop.

John S. Discerni
At MPS, I concentrate on product acquisition and general operations. Because the market for injectable drugs has become so complex, due in part to the limited number of manufacturers, we spend a considerable amount of time to make sure that MPS has the products you need now.
On the personal side, I'm a Cleveland Browns fan. Because the market for Browns fans has become so complex due to the limited number of wins I really don't know why I spend a considerable amount of time to remain a Browns fan. I know that I need help. If you’re in the same boat please feel free to call in to commiserate!

Brad Miller
Where do we start our adventure?
Word on the street is he challenged the great Ron Burgundy to an Indian leg wrestling contest and lived to tell about it. Played in the poker game of the century with his opponents Big Foot, Loch Ness Monster, and the Abominable Snowman. The stakes were high and costly, with the losers going into exile. To test his fortitude, he has walked on hot coals without burning his bare feet. Those closest to him, claimed he could hit a penny at 200 yards with an AR10. Known for being an avid Bears fan, but that’s an extremely dark, depressive, and twisted story these days.
As for myself, I lived in Southern California until 2006. I felt it was time for a change and decided to move to AZ without ever visiting the state. I have been with MPS for a little over a year now. I bring 12 years of experience in logistics, operations and management. In my spare time, I enjoy hiking, playing poker, reading, shooting firearms, and hanging out with my dog. If you have any questions or concerns, please feel free to contact me.

Contact Conner BonebrakeJeffrey Peterson
Hey there! My name is Jeffrey, and I am one of the Account Managers here at MPS. My goal is to make exceptional experiences an everyday occurence for all of my clients. When I am not at work, you will usually find me at home with my wife of 14 years and our 3 darling children. I am also an avid musician, so you may run into me playing guitar, bass or mandolin at a gig or playing on a Sunday morning at my home church. I also build guitars in my spare time, so I am no stranger to sawdust or elbow grease. I'm a long time, die hard Seahawks fan, so Sundays often consist of all 5 of us screaming at the TV, either in the elation of victory or the frsutration of defeat. Win or lose, GO HAWKS!

I have deep roots in both Ohio and Arizona, having lived half of my life in each state.
My passions include my family and the performing arts, particularly live music. My hobbies include cycling, hiking, reading, aviation, and horology. I am a lifelong musician, but the need to make a living required that I hone some diverse skills in customer service and business management.
I am proud to be part of this awesome MPS team, and I am dedicated to the successful relationships we have worked so hard to build and maintain! As with everyone here, please do not hesitate to contact me if I can help in any way!

Contact Joseph StephanyJustin Spiegel
I am one of the newest additions to the MPS team. Originally from Idaho, I’ve spent most of my life in Tucson, AZ. I moved to Scottsdale, AZ in 2013. Which was the best decision ever, anyone that has lived in Tucson knows what I’m talking about.
In my spare time I enjoy traveling as much as possible, continuing with my flight training and of course spending time at the lake. There isn’t much else to do when it is 120 degrees during the summer.
I also enjoy learning everything I can about the drug industry. Please feel free to contact me with any of your questions or concerns. And I will contact someone that knows the answer.
Contact Justin SpiegelKirya Costephens
Hi, my name is Kirya! I moved to Arizona a few years ago to watch my nieces growing up and to stay near family. Before I was a Navy brat, moving from Hawaii, California, and Illinois but settling mostly in Michigan. This move was the hardest for me to make and the heat kills me every summer!
During work hours you can find me in the warehouse running to fill orders or deal with inventory. In my spare time I’m curled up in the AC enjoying a book or a video game, normally with a cat or two curled up with me.

Contact Ryane McKinneySam Hindman
I'm a recent arrival here in the Phoenix area, moving across the country just under a year ago from Massachusetts. Living on the East Coast for my entire life, Arizona has been quite a change in scenery, but an exciting one as I am discovering new places and things to do all the time!
In my spare time I enjoy hiking, reading, playing with my 2 awesome dogs and exploring the beautiful Arizona desert.
Here at MPS you will find me in the warehouse (armed with my trusty can of Monster Energy Zero Ultra) packing up orders and shipping them out, counting inventory, or organizing stock.
I'm more than happy to help with any questions or concerns, or put you in touch with one of our amazing reps who can assist you.
