Our Approach

Crossroads’ goal is to provide supportive medical and psychiatric care to those in recovery. Our downtown Stuart office provides continuation of medical, psychiatric and psychological care, medication management and counseling in an outpatient basis to individuals no longer enrolled in a treatment program.

Crossroads understands the complexities of addiction. Clients are cared by a staff of concerned medical personnel with years of experience in addiction. Our treatment plans are fluid, assessed continually, and modified as needed to be a crucial part of the long term recovery process.

Our Story

Crossroads was founded when Theresa realized that people starting their new sober life could not find any clinics that were trained or specialized in addiction recovery treatments.

People in recovery often struggle to stay in recovery, and having zero medical support is a giant hurdle.  We strive to overcome that hurdle.

Valerie has been a nurse since Prince was singing about the end of 1999.  She started out in 2000 in cardiac care and then transferred to the emergency department where she became a charge nurse shortly thereafter; spent a total of 10 years there. In 2009 she graduated with a Master’s Degree in Nursing, and went to run a Primary Care Practice for 4 ½ years.

In 2012 she expanded her role to help those in need of addiction medicine, specifically in Detox, Recovery and Primary Care Medicine.

I was born in Titusville, Florida and grew up in a very small town of 1200 people just north of there called Oak Hill. I grew up fishing with my family every chance I got. I have four brothers and one sister. When I got to high school I played softball and raised animals for the fair.

In my spare time, I am a pilot and have a wood working shop. I have three dogs, small, medium and extra extra large. My son Kenny is going to high school this year and I am so excited that he is thriving and doing well. He is such a funny and good kid.

As far as my career choice, I wanted to be a nurse since elementary school.  I graduated nursing school at 20 years old and got my bachelor’s degree three years later.  I started nursing back when Prince was singing about the end of 1999.  I worked as a nurse in the hospital, started out in 2000 in cardiac care and then transferred to the emergency department; spent a total of 10 years there, mostly in the ER.  By the time I was 24, I was a charge nurse in the ER.  I thought I wanted to be in management so I went back to school for that.  Then I discovered that I loved taking care of patients more than I liked telling people what to do all the time!  So I became a nurse practitioner in 2009 and have loved every minute of it.

In 2012 I expanded my role to help those in need of addiction medicine, specifically in Detox, Recovery and Primary Care Medicine. I find this career very rewarding and hope to make a difference in the lives of my patients in any way I can.

My focus on health care started when I was a very young Floridian.  I knew I wanted to get an advanced degree of some sort, and with my aunt being a doctor, I had some really great interactions with patients, even as a child.

When I was only 5 years old, she used to take me on hospital rounds (I was not a shy kid).  So, when I turned 15, I went to high school during the day and night school to become a CNA.  Since I was only 16, and still in high school when I earned my certification, no one would hire me, but I finally was able to start working as a nurse’s aide at age 17.  Even though I didn’t love taking orders and giving showers to people, I did love my patients, and it made me want to keep advancing in health care.

I then became a phlebotomist (aka vampire) and worked in a lab drawing blood, processing specimens, and teaching phlebotomy (teaching others how to vampire).  I worked in the lab all throughout nursing school, then attended Indian River State College to earn my Associates Degree in Nursing (2009), and went straight to working as an RN.  Meanwhile, continuing right along with my education path.

While attending Florida Atlantic University, I worked as a mother/baby and NICU nurse, and it was amazing to witness tiny miracles every day.  I graduated from FAU in 2013 with a Dual Degree: Bachelors and Masters in Nursing, and I became a Board Certified FNP (NP-C) through the American Academy of Nurse Practitioners.

Since 2014, I have been working mostly in the mobile setting as a primary care provider and also providing medical services to psychiatric and addiction facilities. I joined the Crossroads team in 2017, and I am so glad that I can continue to provide high level care to patients in recovery in our community.

I have always had a passion for the medical field and come from a family with a long line of nurses!
After graduating high school and receiving my medical assistant certificate, I worked for a primary care physician. Though it was great to take care of patients and being the first person they saw at appointments, I wanted the ability to provide more help. I returned to school and obtained my nursing degree in hopes of becoming an ICU nurse.
But while in nursing school, I had to find a night job my nursing classes were during the day. Stumbling on a job as a mental health technician at a local community mental health agency. I fell in love with the job and haven't looked back since!
After completing nursing school I took a job as a float nurse at the community mental health hospital. Receiving experience working on the geriatric psychiatric unit, adult psychiatric unit, children crisis stabilization unit and the detox/rehabilitation unit, I finally settled as the charge nurse of a 52 bed inpatient acute care unit where I remained for 9 years. After that, more school to get a master's degree as a psychiatric mental health nurse practitioner (PMHNP-BC) from Eastern Kentucky University.
In addition, I have worked at 2 community mental health hospitals and held an outpatient case load. I have extensive experience running an inpatient detox unit and outpatient Vivitrol programs. I am certified through the American Nurses Credentialing Center. I am looking forward to working with you in Crossroads!

Hi my name is Michelle!

I aspire to one day become an accountant, for which I am currently going to school at Indian River State College for my Associates Degree.  I hope to continue my studies and get a Bachelors in the future.  I moved to Florida in 2010 with my mom and step dad from Iowa, living here in Florida has definitely been a different experience and I do miss the cold season.

I started out working at Crossroads Addiction Services as a receptionist and biller, I recently moved up to my position as the Bookkeeper back in December, so now I am the money woman.  I do anything and everything from making sure payments are made on time, to processing bills and invoices, to ensuring payroll and taxes are done on time and are entered into the accounting programs.

I also try to make sure that all our business costumers are up to date with any new financial and customer services features we obtain.  I set up meetings to discuss any problems they may be having or with any confusions on their accounts.

I was born in Illinois, but moved to Florida with my parents at age 5 (lived on both coasts, but settled on the East coast) so, I guess you can call me a Floridian!  My Dad got a job in the West Palm Beach area and we were one of the first families to move into brand new town of Palm Beach Gardens in the 1960's.  I graduated from the new high school and decided to attend Palm Beach Jr. College to become a medical assistant -- which my parents couldn't believe since I could faint at the sight of blood!

I enjoyed the work so much, I went back to college and earned my RN nursing degree in 1976.  I was hired by St. Mary's Hospital after school and after getting experience working on the general floors, moved into intensive care and coronary care units.  I had always, deep down, wanted to be a surgical nurse.  Opportunity rang!  There was an ad in the newspaper (how you got a job in the pre-internet days) for an office/surgical nurse for an Ear, Nose and Throat group.  I ended up working there for almost 37 years. I also obtained my RN First Assistant Certificate in 1990 to assist in surgery.

I love to travel, read, go to the beach and spend time with friends.  Also, during the time I worked with the ENTs, one of them went on medical mission trips to Bolivia to provide surgical services for the indigent and Bolivian Indians.  I went four times with the team and there are really no words to describe the rewards we received from the people we were helping, very humbling experience -- I recommend it to everyone!

My long nursing history and love of helping people will hopefully be an asset to my new career with Crossroads.  Please come see me.

Hi there! I’m Daniel, but friends and family call me Danny.

I was a Navy brat (child of a military family) so the family moved all over the east coast. I grew up in south Florida, and joined the Navy April 2010. Originally as an Electrician specializing in nuclear power distribution. Then I deployed for Operation Inherent Resolve for ten months, escorting the aircraft carrier Harry S. Truman, conducting multiple vessel boardings, gathering intelligence, searching for weapons and drugs. All in an effort to reduce funding for terror groups in the Middle East.

Later, I was selected to forward deploy out of Sasebo, Japan for 2 years. I began working with Naval hovercrafts and deployed in the west Pacific for multiple reasons ranging from typhoon relief efforts to international naval exercises.

While in japan I attended college, working towards a degree in electrical engineering and business management. I am currently enrolled in University of Maryland University College (UMUC). Now as the Information Technology Coordinator (aka computer weenie jr.) I assist the team by making sure all of the computers, the network, and the software all run smoothly. I also provide support for various systems around the office, and try to help where I can; from cleaning up a mess to helping a customer jump their car.

Back in 2005, Tramp forced Chip to adopt her from the pound.  Since then she has been Chip and Theresa's companion.

In her younger years, she liked to chase squirrels and anything that moved.  She then went on to herding cattle and horses -- ensuring all the farm animals knew who the barnyard boss was.

Now she is the welcoming committee for Crossroads.  When she's not hard at work supervising Crossroads, she particularly likes it receiving treats from our guests, so we have a whole bunch tucked away for her.
