The Ten People Who Run This Place

Five of them are Doctors of Physical Therapy and they are the only five who evaluate, diagnose and hold a plan. The other five coach strength, do massage and run the front desk, and we keep that line straight on purpose.

01 How we hire 01 / 07

The standard we hire to.

Five of the ten people here are Doctors of Physical Therapy. They are the only five who evaluate, diagnose and write a plan of care, and the doctorate is the entry fee rather than the interview. Before an offer goes out we watch a candidate run an actual evaluation, because the real test is whether they can say what is wrong and why in language a person who has never heard the word biomechanics can follow. If that does not happen across a table from us, it will not happen at 7am on a Tuesday with somebody’s shoulder.

If you read a staff page before booking, that is not fussiness. Hands-on care means an actual person’s hands, and wanting to know whose they are before you show up is a reasonable thing to want.

The other five are not clinicians and we do not describe them as any. They coach strength, they do massage, they run the front desk. Each of those is real work that sits alongside a plan of care rather than standing in for one, and the second grid on this page is separate for exactly that reason.

02 The doctors 02 / 07

Five Doctors of Physical Therapy.

Dr. Nick Hadinger, PT, DPT, owner of Streamline Performance Physical Therapy in Phoenix, AZ
Dr. Nick Hadinger · Sports and orthopedics

Dr. Nick Hadinger ⟶

Sports and orthopedics · PT, DPT, USAW-1

Owner. He treats shoulders, backs, hips and knees, before surgery and after it, and he holds a USA Weightlifting coaching credential, which shows up in how he loads a rehab rather than in what he says about it. Arizona native, physiology at the University of Arizona, Division I swimmer there, then a doctorate from Northern Arizona University. He still races triathlons, so he is usually managing his own training week alongside yours.

Dr. Lauren Mueller, PT, DPT, Clinical Director at Streamline Performance Physical Therapy in Phoenix, AZ
Dr. Lauren Mueller · Golf performance

Dr. Lauren Mueller ⟶

Golf performance · PT, DPT, CDN, TPI Cert. M2

Clinical Director. Orthopedics and sports medicine, with golf performance as the specialty she gets asked for by name. A golf evaluation with her starts with how your hips, thoracic spine and shoulders actually move, then works back toward why the swing does what it does. She has been a clinical instructor since 2018, which is a reasonable test of whether a clinician can explain their reasoning out loud.

Dr. Ryan Spencer, PT, DPT, OCS, board-certified Orthopedic Specialist at Streamline Performance Physical Therapy in Phoenix, AZ
Dr. Ryan Spencer · Orthopedics

Dr. Ryan Spencer ⟶

Orthopedics · PT, DPT, OCS, CSCS

Director of Leadership and Clinical Mentorship, and a board-certified Orthopedic Specialist, a credential earned after the doctorate rather than inside it. He is also a purple belt in Brazilian jiu jitsu, so he has a working relationship with the joints that grappling tends to find first. Midwestern University named him its Most Outstanding Clinical Instructor in 2019.

Dr. Krista Zelizney, PT, DPT, pelvic floor and women’s health at Streamline Performance Physical Therapy in Phoenix, AZ
Dr. Krista Zelizney · Pelvic floor

Dr. Krista Zelizney ⟶

Pelvic floor · PT, DPT, Female Pelvic Floor L1/2a/2b

Pelvic floor and women’s health, sitting on top of an orthopedic background, which is why an evaluation with her rarely stops at the pelvis. Leaking on a run, pressure that gets worse by evening, a midsection that never came back after a birth: those are the cases that fill her day. Her pelvic floor training runs through Levels 1, 2a and 2b.

Dr. Jake Lape, PT, DPT, male pelvic floor therapist at Streamline Performance Physical Therapy in Phoenix, AZ
Dr. Jake Lape · Men’s pelvic health

Dr. Jake Lape ⟶

Men’s pelvic health · PT, DPT, CSCS, UDN-C

Male Pelvic Floor Therapist, which is a thing most men in Phoenix did not know they could book. He also carries a strength and conditioning credential and a dry needling certification, so the rest of his schedule is sports and orthopedic work. Men’s pelvic symptoms usually get treated as a plumbing problem for a year or two before anyone checks the muscles involved.

03 Strength, massage and front office 03 / 07

Strength, massage and the front desk.

Brittney Kelly, Office Coordinator and Client Experience Specialist at Streamline Performance Physical Therapy in Phoenix, AZ
Brittney Kelly · Front office

Brittney Kelly ⟶

Front office · Office Coordinator and Client Experience Specialist

She is the first voice on the phone and the person who gives you the rate before you book, which is not a small job at a practice that does not bill insurance directly. A healthcare administration degree and more than ten years of healthcare admin sit behind that, which mostly means very little about a schedule surprises her any more.

Monty Montgomery, Strength and Conditioning Coach at Streamline Performance Physical Therapy in Phoenix, AZ
Monty Montgomery · Strength and conditioning

Monty Montgomery ⟶

Strength and conditioning · Strength and Conditioning Coach

Powerlifting is his background, and it shows in how he coaches a barbell: slow, specific, and largely unbothered by how much weight is on it. He runs the small group fitness sessions, which is where a lot of people land once a plan of care has finished and they want somewhere to keep the strength they just spent six weeks building.

Rachel Reidy, Licensed Massage Therapist at Streamline Performance Physical Therapy in Phoenix, AZ
Rachel Reidy · Massage therapy

Rachel Reidy ⟶

Massage therapy · Licensed Massage Therapist

Fifteen years of practice and a certification in orthopedic massage, which is the version aimed at one structure rather than a general hour of quiet. She works the tissue around the joint a plan is already addressing, so that the range someone gained on the table has a better chance of still being there next week.

Gabby Foxworthy, Strength and Conditioning Coach and Receptionist at Streamline Performance Physical Therapy in Phoenix, AZ
Gabby Foxworthy · Strength and conditioning

Gabby Foxworthy ⟶

Strength and conditioning · Strength and Conditioning Coach and Receptionist

She trained under the pole vault gold medalist from the 2000 Olympic Games, which is an unusual line on a resume and a useful one, because vault coaching is mostly the art of sequencing a body through positions at speed. She also runs the front desk, so she is often both the person who checks you in and the person coaching you an hour later.

Grant House ⟶

Strength and conditioning · Strength and Conditioning Coach, CSCS

Nine years on Team USA as a swimmer, with medals from the Pan American Games and the World University Games, and an Arizona State degree behind all of it. He holds the CSCS and works the strength side of a plan a clinician has already written. Nine years of international swimming also gives him a long personal history with the shoulder, which is the joint the sport eventually asks about.

04 What they have in common 04 / 07

What all ten have in common.

Whichever doctor ends up holding your plan, the shape of it is the same. The evaluation is cause-first, which means the first appointment goes to finding why it hurts rather than confirming where. Every plan moves through the same four phases, Pain, Prime, Perform, Prevent, in that order. Every visit is 60 minutes, one-on-one, with the same doctor from the first handshake to the last rep, and no handoff to somebody else partway through.

You will also be told out loud, at the evaluation, roughly how many visits this should take and what finished is going to look like. We are a cash-pay practice and do not bill insurance directly. That is the trade that buys the full 60 minutes one-on-one, and it means you get the rate before you book rather than a statement afterward. Arizona allows direct access to physical therapy, so you can book an evaluation without seeing anyone else first.

05 In a patient’s words 05 / 07

One patient, on the whole staff.

“The staff is knowledgeable, attentive, and always takes the time to make sure you feel comfortable and supported during each visit. I’ve really enjoyed coming here and can already feel the difference in my recovery.”

06 The intake 06 / 07

Put it in writing.

Five short questions. A real person calls you back, usually within two business hours, with times that fit your week.

The people who end up filling this out are rarely in the worst pain of their life. They’re just done working around it, done picking the errand that doesn’t require the stairs. If that’s the stage you’re at, this is the part where you stop researching and start.
