Meet Our Staff

Rey Rivera
Medical Staffing Agency President
Rey David Rivera is the President and CEO of TheraEx Staffing Services, a staffing company that aligns nurses and Allied Professionals with the right organization, setting and position that meets their needs in a dynamic, changing healthcare marketplace.
As an actively practicing registered licensed Occupational Therapist himself, Rey understands the important relationships and the trust that healthcare providers place in the hands of recruiters. He has a unique perspective of what it is like to be a therapist in
search of the right position; a hiring manager and representative of organization looking for that “right person” that fits organization’s culture; as well as the challenges in finding a staffing agency that actually listens and appreciates what you have to offer.
It is his passion to ensure that TheraEx knows who you are, knows your story, and what drives you so you can provide the exceptional care that your patients deserve. As part of this overall strategy, he has ensured that TheraEx Staffing is an active member of Minority Business Enterprise (MBE) and has received and maintained certification as an MBE with the National Minority Supplier Development Council (NMSDC).
Before devoting his time in creating TheraEx’s unique individualized culture in 2009, Rey served as a licensed professional and leader across numerous healthcare settings for more than 17 years. This includes Area Manager for Hallmark Rehabilitation, Vice President of Rehabilitation at JPH consulting, Inc., Regional Rehabilitation Manager at Bethel Healthcare from 2008, Director of Rehabilitation Services at RJ Therapy, Director of Rehabilitation Services at Mariner Health Care, and a treating Occupational Therapist for a staffing agency whose clients include SNFs and acute hospitals.
After completing his MBA in 2010, Rey got inspired to merge his extensive healthcare experience and unique perspective while applying his entrepreneurial passion to building TheraEx Staffing. In 2019, Rey recently graduated from Goldman Sachs 10,000 Small Businesses, as an investment to TheraEx as a small business so it can continue to create jobs and economic opportunity.
Outside of work, Rey enjoys watching movie marathons; spending dinner dates with his ex-girlfriend (a.k.a. his wife) and coaching basketball to his three sons.

Crystal White
Director of Operations
I started in the Healthcare Industry in 2006 doing risk management for Physicians in Dallas. That’s when I fell in love with healthcare staffing. I started my Recruiting career in Physician Recruitment then moved to California where I built experience with Nurse Staffing.
In 2016 I joined the TheraEx family as the Director of the Nursing Division. My favorite thing about what I do is not only the fact that every day is different, but that I get to make a difference in people’s lives by providing jobs and supplying facilities with people who provide excellent care to patients.

Vanessa Cueva
Clinical Division Director
I first started my career as a Healthcare Credentialing Specialist in 2013 for nurses at a Medical Staffing Agency. I like the day to day challenges that come with working in the credentialing field because it makes your days interesting and every day is different!
I graduated in 2011 with my BA in Criminal Justice. I think my degree played a huge part in why I love credentialing because it is very analytical and challenges me each day. I joined the TheraEx team as the Clinical Compliance Manager in 2016 for the Nursing Division. Here at TheraEx, my goal is to provide our clients with the best clinicians possible in the timeliest manner.

I started my career in healthcare staffing in 2012. I worked as a credentialing coordinator for about 3 years before I transferred into healthcare recruiting. I had prior experience recruiting for a call center and knew pretty early on that I wanted to develop my career into the recruiting field again, but within healthcare. I’ve now been in healthcare recruiting for about 5 years and counting. I enjoy what I do; helping others find their career paths and develop themselves into the healthcare professional their seeking to become.
When I am not working, I am usually with my wonderful husband and our beloved fur-child. He’s a Great Dane who is spoiled rotten and we spend a lot of our free time with him. We love going out on the trails here locally off Lake Lanier. The lake and mountain views are gorgeous! We also are gamers and spend time gaming together and with friends live.

Mohamad Qashamar
Sr. Clinical Recruiter
Hi my name is Mohamad, and I was born and raised in the vibrant city of Dallas, Texas.
My life is a blend of family togetherness, the excitement of watching my sports teams play, dedication to fitness, and the tranquility of nature. Whether it’s a backyard barbecue, fishing, or hitting the gym to stay fit and energized, I find joy in these simple pleasures.
Beyond my personal interests, I’ve been working as a travel nurse recruiter for several years, and I’m incredibly passionate about what I do. I’m able to help save so many people and lives. It’s very fulfilling to play a part in providing both healthcare professionals and facilities with the support they require, making a positive impact in the healthcare community.

Jessica Sam
Sr. Clinical Recruiter
Hi, my name is Jessica and I’m from Los Angeles, CA born and raised. I have 10 plus years of customer service and client success experience. I officially started my recruitment career in 2018 and since then I have been full cycle recruiting top talent throughout the US. In 2020 I made it into the healthcare recruitment industry, where my passion lies. I enjoy making both clients and candidates ecstatic about their future partnership, but perhaps even more satisfying is seeing a candidate’s growth. I’m happy to say that I’m in the business of caring.
When I’m not recruiting, I am very active with my family; basketball, football, working out, cooking, and from time to time a fun 3 marker drawing challenge or arts and crafts. However, when I’m not Jessica or mom, I am coach J and support our community youth in any way possible.

John Zavalza
Sr. Clinical Recruiter
My name is John and I have been connecting people with their next great opportunity since 2019. I graduated from Cal State University San Bernardino in 2019 and I truly had no idea which direction I wanted to go in with my Bachelors in Sociology. However, one thing I did know, is I wanted to make a difference in people’s lives, but I just didn’t know how. Then I accidentally applied for a healthcare recruiter position, and it has been Valhalla ever since. Not only do I make a difference in the lives of the patients that our nurses work with, but the nurses that I have the pleasure of serving as well. Having the opportunity to walk hand in hand with a medical professional through their career path has been the most rewarding experience I could have hoped for.
When I am not playing matchmaker between nurses and their next opportunity, you can find me frantically running after my 2-year-old daughter. I also enjoy spending time with family and friends going to the gym as well as being active with friends.

Kahlen Donatell
Sr. Clinical Recruiter
Kahlen here- but you can call me KD! Currently embracing the city life in Minneapolis with my dog Goose, weathering winters cheering for the Bucks, Packers, & whoever I started in fantasy football. Always down to get together with friends, hit up a concert, or opting for some quality Goose time.
Having worked in finance to start, I switched gears to recruiting a couple of years ago and found my niche helping healthcare professionals achieve their career goals. Getting the opportunity to interact with & meet new people is something I thoroughly enjoy.

Mackenzie Maier

I’ve been working in the healthcare recruiting space now for almost 1.5 years and previously worked in the pharma industry. In my spare time I enjoy going to the beach, traveling, and spending time with family/friends. I can’t wait to help you find your next travel gig and look forward to working with you!

Kerem Perk
Sr. Clinical Recruiter
I was born into a family of nurses in Eastern Europe and grew up hearing the craziest patient stories & hospital conditions of the late 90s. Naturally so I found my calling in recruiting during the worst days of the pandemic in 2020. As chaotic as that time was for all of us working in healthcare, this was a match made in heaven for me. I have a Marketing degree and a good understanding of its principles, allowing me to better help my team of clinicians reach their goals and continue our family tradition in some way. I’m aware of all the troubles of working on the floor, hence the least I can do is work my hardest to get you where you want to be. God knows I’d not be able to pass an Arrhythmia test..
When I’m not by my laptop working, I’m either looking up recipes from different cuisines or working out. I love to travel and was fortunate enough to live in France, Australia, and a few different regions in the U.S. before settling down in the beautiful Midwest. I’ve been residing in Minneapolis, MN for the past 7 years and yet continue to question this decision every winter. I LOVE meeting folks and exchanging stories, I’m sure we’ll have plenty to talk about!!
